Platform engineering is no longer a niche function within IT. It is the cornerstone of modern digital enterprises. As businesses prioritise scalability, agility, and resilience, platform engineering is at the forefront of enabling innovation through infrastructure optimisation, automation, and AI integration. In 2025, platform teams are evolving from infrastructure providers to strategic enablers, driving business agility and innovation. This article explores key trends shaping the landscape of platform engineering, as informed by Gartner’s Top 10 Strategic Technology Trends for the upcoming year.

In this article, we take you through the hype cycle for platform engineering in 2024 by Gartner. As you can see, platform engineering has experienced a massive surge in recognition, with the discipline now appearing on over 10 different Gartner hype cycles—a nearly 5x increase from last year. Notably, there is now an entire hype cycle dedicated to platform engineering. This growth is mirrored in the platform engineering community, with job titles on LinkedIn and interactions at major conferences like PlatformCon showing a strong, upward trend.

Additionally, infrastructure platform engineering, a key subdiscipline, has been featured in 8 different hype cycles, including those for Cloud Computing, SRE, and I&O Automation. This further highlights the increasing importance of platform engineering in driving innovation and business transformation. As Chief Technology Officers (CTOs) seek to drive their organisations forward, platform engineering emerges as a critical focus area, empowering them to achieve unparalleled levels of efficiency, security, and innovation.

This overview of platform engineering trends will be concise and focused, presenting a streamlined list of key insights.

What is happening to platform engineering in 2025?

By 2026, 80% of large software engineering organisations will establish platform engineering teams as internal providers of reusable services, components, and tools for application delivery — up from 45% in 2022. This reflects the growing recognition of platform engineering's role in simplifying development processes and enhancing productivity, and this is exactly where the AI-powered platform engineering trend first starts to emerge.

As we already know, AI/ML is deeply integrated into platform operations, automating tasks like infrastructure provisioning, resource allocation, and incident response. Thus, AI in platform engineering enhances operational efficiency and reduces manual effort for platform teams. It improves resource utilisation and optimises costs through predictive analytics while enabling faster incident resolution and better application performance with proactive monitoring and anomaly detection.

For example, a platform team can use AI to predict and automatically scale resources based on anticipated demand, ensuring optimal performance and cost-effectiveness.

Platform architectures are becoming more modular and flexible, making it easier for businesses to adapt quickly to changing needs. By reusing pre-built components and services, teams can develop and launch applications faster while staying agile to respond to market shifts and customer demands. This approach also improves scalability and makes platforms easier to maintain over time.

For example, a financial services company could create a platform with reusable modules for authentication, payment processing, and data analytics, allowing it to roll out new financial products more quickly and efficiently.

Case in point, Bob Simms, director of enterprise infrastructure delivery at the US Patent and Trademark Office (USPTO), highlights how their platform engineering teams support over 200 applications by focusing on automation and observability. “We went from weeks to get a deployment done to minutes,” says Simms.

This rapid deployment capability is paired with infrastructure service-level monitoring and automated responses. “If we have a particular type of outage, our observability tool can also restart the application.” Such innovations demonstrate how composable platforms enable both scalability and resilience.

Security is now built into every stage of the software development process, with platform teams playing a key role in enforcing security policies and best practices. This integration helps reduce vulnerabilities and strengthens the overall security posture, while also speeding up the identification and fixing of security issues, by eliminating security-related obstacles, developer productivity increases.

Moving onto an example, a platform team might adopt security-as-code principles, automating security checks and ensuring that security policies are followed throughout the entire application lifecycle.

Further emphasising the role of structured pipelines, Sanjay Srivastava, chief digital strategist at Genpact, explains how platform engineering streamlines processes. “Platform engineering allows us to build a common pipeline and methodology for every product we deploy,” he says. This consistency not only simplifies security enforcement but also addresses talent gaps.

“We found this particularly helpful when it comes to skills and talent, which are hard to find and retain.”

4. Multi-Cloud and Hybrid Cloud Strategies

Platform teams are increasingly managing infrastructure across multiple cloud providers and on-premises environments as part of multi-cloud and hybrid cloud strategies. This approach provides flexibility, scalability, and resilience while optimising costs by leveraging the strengths of different providers. Organisations can mitigate vendor lock-in, enhance disaster recovery, and tailor infrastructure to business needs. For instance, a retail company might adopt a hybrid cloud strategy by using the public cloud for scalable e-commerce and a private cloud for sensitive data, ensuring both performance and security.

For CTOs, these strategies are critical to driving innovation and ensuring business continuity. Multi-cloud adoption reduces dependency on a single vendor, enabling cost-effective scaling and improved risk management. CTOs can leverage these approaches to modernise IT operations, support AI-driven applications, and enhance collaboration across teams, ultimately delivering faster and more reliable services.

Platform engineering plays a key role in enabling these strategies by abstracting infrastructure complexities and automating tasks like provisioning and scaling. Tools such as VMware vRealise, HashiCorp Terraform, and Microsoft Azure Arc help standardise operations, ensuring seamless integration and consistent performance across diverse environments. This allows CTOs to maintain operational efficiency and security while focusing on strategic growth.

A significant majority of enterprises, over 84%, have adopted multi-cloud strategies to enhance cost efficiency, and business agility, and leverage top-tier services from various providers. According to Google, it is expected that more than 85% of organisations will adopt a cloud-first approach by 2025, with over half utilising multi-cloud strategies to foster business innovation and accelerate digital transformation.

In platform engineering, success hinges on providing a great developer experience. Just like a company’s performance is often judged by customer satisfaction, a platform engineer’s impact is measured by how easy and enjoyable it is for developers to work with the platform.

If the platform feels clunky, overly complicated, or inefficient, developers won’t want to use it. And if developers don’t use it, the platform’s value drops significantly.

At PlatformCon2024, Darren Evans (EMEA Practice Solutions Lead, Application Platform) delivered a talk titled "Improving your developers' platform experience by applying Google Frameworks and Methods”, where he discussed Google's HEART Framework, which offers a comprehensive perspective on the developer experience within an organisation by using actionable data. This was a major point in creating developer experience as a trending pinpoint for 2025 in platform engineering.

In platform engineering, the HEART framework can be adapted to fit different goals and situations. For example, enhancing the onboarding experience for new developers might prioritise adoption, task success, and satisfaction. On the other hand, rolling out a new feature could focus more on adoption and happiness. To boost overall platform usage, it may be important to track metrics like engagement, retention, and task success.

Platform teams are increasingly focusing on improving the developer experience by offering self-service tools and easy-to-use interfaces. This shift leads to higher developer productivity and satisfaction, as it reduces the need for platform teams to handle routine tasks. As a result, teams can launch new applications and features more quickly. A platform team might provide a self-service portal that allows developers to provision resources, deploy applications, and monitor their infrastructure without needing constant assistance from the platform team.

Platform engineering in 2025 is evolving rapidly. By embracing these trends, platform teams can empower developers, drive innovation, and deliver exceptional business value. As technology continues to advance, platform teams will play a critical role in shaping the future of digital enterprises.

Platform engineering has become a key focus in IT and operations (I&O) as companies work to handle the growing complexity of cloud-native and distributed systems. Over the past decade, more organisations have adopted platform engineering to simplify workflows and better support their development teams. These efforts have come a long way, proving they can boost scalability and improve developer productivity.

The platform engineering community has also grown, with over 15,000 engineers now sharing ideas and best practices. Events like PlatformCon 2023, which recently held its second edition, show how much interest this field is gaining. These conferences are a great way for CTOs and tech leaders to stay updated on the latest trends, tools, and strategies shaping the future of platform engineering.

This article is based on sources such as Gartner, cio.com, and studies based on industry trends. The specific impact and relevance of these trends may vary depending on the individual organisation and its specific needs.

I hope this article provides a valuable overview of platform engineering trends for 2025!

Platform Engineering Trends in 2025: A CTO's Guide

This article is aimed at test analysts and other stakeholders who engage in software quality assurance in a managerial capacity. The article discusses some of the unique challenges and opportunities associated with testing an Internal Developer Platform product like SkyU and shares a few reasons why buying one is better than building one in-house.

The International Software Testing Qualifications Board defines testing as “a set of activities to discover defects and evaluate the quality of software artifacts” [1]. Typical software testing activities include activities such as analysing requirements, designing test cases, executing test cases, and comparing expected results with the actual results to identify defects. Based on criteria such as the product architecture, technologies, and business requirements, these testing activities' effort, complexity, and risk tolerance can vary greatly.

To understand this idea, imagine how a product team developing a food order management system for the internal use of an organization might settle for simpler less effortful solutions with higher risks related to the quality of their product compared to a mission-critical food order management system that is built to cater to an entire nation which would demand a much lower tolerance of risk at higher complexity and effort. SkyU, as a PaaS product open to organisations with product development aspirations on both ends of this spectrum, the SkyU QA team has to ensure the product meets the quality assurance expectations of both mission critical software projects as well as software projects catering to trivial business needs.

Challenges and Opportunities Testers of Platform Engineering Products Can Expect

The challenges of testing a platform engineering product like SkyU can be categorised into,

Challenges that arise from the large number of 3rd party services and technologies that need to be bundled in.

Challenges associated with conducting manual and automated end-to-end testing.

Though internal developer platforms are built specifically to meet an organisation's needs, with an OOTB platform engineering product like SkyU, you can't offer a narrow set of features and configurations. This results in the need to support a large number of third party services such as Github Actions, Docker Hub, AWS EKS, and ChatGPT, as well as technologies like Docker, Kubernetes, Helm, and Kustomize. These services and technologies need to work seamlessly across the various layers that make up the product. From a quality assurance perspective, the interconnectedness of these components increases testing activities.

When it comes time to design test cases, a tester will analyse the functionality offered by these 3rd party services and identify how it relates to the functionality offered to the end user. The tester will then employ test design techniques such as 

pairwise testing, decision tables, state transfer diagrams,

 to design the optimal number of test cases to cover the feature. A pain point unique to IDP products to this end is the identification of all the expected results for a given test case.

For example, if a new Cloud CI service is being introduced as a feature (say BitBucket), when creating test cases, a tester may need to identify the expected results to look for in the GUI under the ‘Developer Control Plan’, ‘Integration’, and ‘Delivery Plane’ and the ‘Monitoring Plane sections’. The tester will then need to identify any expected results related to the database that is only accessible through the API layer. Finally, the tester will need to look at the expected results that need to be accessed in the 3rd party service, such as the commit history or pipeline information.

Another pain point associated with testing IDP products is the complexity involved in creating end-to-end test automation scripts. The automation scripts require adaptation to interface across multiple services, architectures, and interface types while maintaining synchronisation between the scripts and the system under test. This is to ensure a reliable test execution.

However, it's not all pain for the tester, as Churchill is known to have once said “A pessimist sees the difficulty in every opportunity; an optimist sees the opportunity in every difficulty”, the very challenges associated with testing an IDP can be the strengths that can propel the careers of testers of an IDP product past that of their peers in this day and age of AI prompt based software engineering. As testers work their way into the innards of the product, they will get opportunities to up their DevOps skills and knowledge which is still highly sought after. Coupled with their experience in quality assurance, they will be able to uniquely position themselves in the job market.

The benefit of going with platform engineering products on an organisation's software quality assurance function

One of the main selling points of going with a platform engineering product like SkyU, as opposed to building a platform in-house, is the lowered cost of ownership. One reason why this is a valid point is the quality assurance-related effort that goes into the delivery of an IDP product. Organisations can piggyback on the process of testing which the vendor has already put into the product. They can benefit from the feedback cycle from other users who’ve used it and the community as a whole.

Ideally, the IDP product vendor should ensure the quality of the three lower levels of the test pyramid. That is the component level testing through developer unit tests; integration level testing through component integration testing and API testing and system level testing through end-to-end testing. Meaning, organisations can focus on the different acceptance tests such as operational acceptance, regulatory acceptance, and user acceptance. All of this will lead to a cheaper and faster ownership of the IDP.


In summary, this post aimed to provide an overview of the challenges and opportunities that IDP product testers may encounter. It also highlighted the benefits organisations can gain by purchasing an IDP rather than building one in-house, particularly in terms of the advantages it offers to the quality assurance function and the impact on the bottom line.

Testing an Internal Developer Platform: Why Out-of-the-Box Solutions Make Sense

TLDR: We launched automated release management for SkyU.io! Share, discover, and implement the feature built to automate your experience as a release manager. Learn how, why, and what to try first, below.

Hey all, Heshan here. Here’s a little about the "Project Releases" feature the team has been working on.

If you've ever shipped software, you know the drill. Release days can be absolute nightmares. Last-minute fixes, versioning confusion, and that awful moment when something goes wrong in production... it's hectic!

But with "Project Releases," we're finally tackling this head-on.

Streamlined releases, from start to finish:

 Get a clear view of your entire release process, from code freeze all the way to deployment. No more scattered tools and endless email chains.

Automation that actually makes a difference:

 Ditch the manual work and embrace automated deployments, testing, and even rollbacks.

Ship with confidence, every single time: 

"Project Releases" helps you reduce errors, keep tabs on your progress in real-time, and release with peace of mind.

In the end, we’re building a culture where releases are smooth, reliable, and even (dare I say) enjoyable. We want to help you reclaim those release days and turn them into a celebration of your team's hard work.

So give "Project Releases" a shot and let us know what you think! We're always looking for feedback.


Solving for X: So what is “Project Releases”?

Imagine the time and effort involved when getting your application deployed out there. In most development cases, this consists of the deployment of multiple environments for the app as well. It could be development environments, staging environments, or production environments. It could be N number of environments depending on the specific deployment strategy followed by a specific team.


Now imagine having a microservices architecture. Each service is deployed across multiple environments, collectively working together to provide functionality to an application. With each new service and environment, the deployment 

 increases drastically while also introducing a lot of other challenges.

How do you track applications that are up to date?

Did each application deploy successfully?

If one fails, do you proceed with the deployment of others?

If one failed, where and why did it fail?

Moreover, these services and applications can be of many different types. Mobile apps, web apps, Kubernetes orchestrations, Lambdas, etc.


The SkyU platform offers a wide range of features when it comes to deployments, and one of its core features is “Project Releases”.

We built the Project Releases feature to simplify and streamline the deployment process for software release/delivery teams. As we discussed, as applications grow in complexity, managing multiple services and their dependencies becomes increasingly difficult. This feature enables release managers to handle all applications and their dependencies as a single “bundle”. This makes it easier to maintain consistency, reduce human error, and improve deployment efficiency. By offering the ability to promote or roll back multiple components at once, we empower teams to deploy with confidence and agility. Save time and reduce the risk of deployment-related issues.

Let’s imagine a simple coffee shop scenario. The overall project is the coffee shop itself, which we’ll call “Bean & Brew.” This project includes a website (a web application) and services for handling user authentication, orders, carts, and catalogues (containerised APIs).


Once we create these five applications in SkyU service catalogue, the setup might look something like this:

Let’s take a look at how we can overcome the above-mentioned challenges in the context of Bean & Brew.

At a glance, this can be seen via the colour variations. However, behind the scenes, SkyU compares commit SHAs. Why? So you don’t have to!

The development environment is updated each time changes are made in the application repositories, thanks to straightforward “Git” operations running in the background. If your team follows a specific branching strategy, “Staging” and “Production” environments are also updated periodically through designated branch patterns and merges. However, the SkyU project release feature is flexible and will work even if you have just a single main branch for each application.


How do you deploy EVERYTHING, EVERYWHERE ALL AT ONCE?

SkyU makes it easy to promote these applications across environments, giving complete control to the person handling the release. You can choose to deploy all applications at once or selectively pick the ones you want to deploy.

This will start the deployment process of these applications as you can see here.

Give it a few minutes and then it’s done.

Did individual applications deploy successfully?

Yes, and you can confirm this visually from the SkyU console. The platform verifies that all promoted applications were successfully deployed. Verifying updates depends on the application type: for instance, if it's a web application, you only need to check if the newly promoted environment reflects the changes from the previous environment.


If even one application fails, the deployment enters a "Ready to deploy" state. From here, you can decide whether to partially deploy the successful applications. This decision is left to the user and may depend on factors such as the interdependencies between services.

To demonstrate, let's intentionally fail a deployment. A failed deployment is marked with a red dot, which links to the pipeline's execution logs, showing where and why the issue occurred.

The specific issue can be uncovered from these logs afterwards. Along with many other SkyU features like AI-powered debugging and AI-suggested solutions to fix these issues.

Rollbacks are just as simple as releases. This is because SkyU tracks the release history of your project.

This makes it so that going back to a previous deployment is as easy as selecting the deployment you want to roll back to. That’s it.

This approach works seamlessly for a straightforward project, like our Coffee shop example. But what about a more complex scenario? We decided the ultimate test case for SkyU was… SkyU itself. Enter the concept of “SkyU on SkyU.”


SkyU is a sophisticated application, with over 25 microservices and a continuously evolving tech stack. And, currently, 100% of SkyU’s deployments are managed by SkyU itself. This automation allows our developers to focus on development rather than deployment complexities, making “SkyU on SkyU” a true showcase of the platform's potential.

In our view, deployment doesn’t get more complex than this. And if it does, it may signal inefficiencies in the process. That’s where we can help, so feel free to reach out if you're facing deployment challenges.

Experience the power of SkyU's seamless deployment management for yourself. Get access to the “Project Releases” feature in any of the pricing tiers available with the SkyU platform (Startup, Growth or Enterprise).

Introducing “Project Releases” on the SkyU Platform

In platform engineering, two common metaphors illustrate the impact of design choices: 

. Both represent an opinionated approach to platform design, but their outcomes are strikingly different. This article explores the delicate balance between structure and flexibility, the importance of avoiding traps, and how the decision between 

Golden Path: Guidance Without Restriction

 is the ideal many platform teams aspire to create—a curated experience that provides developers with a smooth, efficient, and secure route to deliver value. By using standardised workflows, approved tooling, and best practices baked into the platform, developers enjoy:

: Reduced complexity for new team members.

: Fewer distractions from operational tasks.

: Compliance and reliability are built into the workflow.

. Developers can choose to diverge from the opinionated path when their use case demands innovation or customisation, enabling them to tackle unique challenges without hindrance.

Golden Cage: Over-Optimisation Gone Wrong

, on the other hand, results when platforms are designed with too many constraints, turning guidance into restrictions. Developers might find themselves stuck in rigid workflows that don't cater to their unique needs or the evolving demands of the business. This happens due to:

: Tools and processes that cannot evolve with technology.

: Developers spend more time bypassing the system than delivering value.

The Golden Cage stifles innovation, frustrates teams, and ultimately slows down the organisation.

Flexibility is the antidote to the Golden Cage. A great platform balances opinionated guidance with the freedom to adapt. Here's why flexibility should be at the core of any platform:

: Teams can innovate without being locked into a single way of working.

: Platforms can grow with the organisation, integrating new tools and workflows as needed.

: Flexible systems adapt to change, preventing obsolescence.

Flexibility doesn't mean chaos; it means offering curated paths with the option to step off-road when necessary.

 your platform profoundly affects whether you achieve a Golden Path or fall into a Golden Cage. Each approach has its merits and trade-offs, and the right choice depends on your organisational goals, resources, and expertise.

Building your platform offers the ultimate in customisation. With tools like Spotify's Backstage, organisations can create a fully tailored experience. However, building is not without challenges:

: Building an internal platform requires a significant upfront commitment in terms of time, money, and skilled personnel.

: A dedicated platform engineering team is essential for development, iteration, and maintenance.

: Beyond the initial build, ongoing upkeep, scaling, and adapting to new technologies demand continuous effort.

While building offers complete control, the cost in resources and operational burden can be prohibitive for teams without extensive platform engineering expertise.

Buying a platform offers an immediate return on investment (ROI), especially for teams that need to hit the ground running. Solutions designed for internal developer platforms (IDPs) deliver:

: Platforms like SkyU provide workflows, integrations, and compliance out of the box, minimising the time to value.

: Prebuilt platforms reduce the need for large platform engineering teams, freeing resources to focus on business outcomes.

: Vendors often provide ongoing updates and support, ensuring the platform stays relevant as your organisation grows.

Buying a platform lets you focus on delivering software rather than building infrastructure. It strikes a balance between the Golden Path’s efficiency and the flexibility needed to avoid the Golden Cage.

In platform engineering, the difference between a Golden Path and a Golden Cage comes down to design choices that prioritise flexibility and developer empowerment. Whether you choose to build or buy, the goal should be the same: to create a platform that enables developers to deliver value efficiently while preserving the freedom to innovate.

For teams ready to invest deeply in customisation, building a platform may offer unmatched control—but it comes at a cost. For those seeking immediate productivity gains and long-term adaptability, buying a solution offers an easier path to success. Platforms like SkyU exemplify this approach, enabling teams to embrace the benefits of the Golden Path without the risk of becoming trapped in a Golden Cage.

Golden Path vs. Golden Cage in Platform Engineering: Why Flexibility Matters

In the fast-paced world of Formula 1, speed and precision are everything - every millisecond counts and a tiny misstep can mean missing out on the podium. It’s a lot like platform engineering, where the goal is to deliver software quickly and efficiently while juggling complex systems. Just as F1 teams fine-tune every detail, from engine performance to pit stops, platform engineers analyse data and make split-second decisions to stay ahead. The bottom line? In both, being “slow and steady” just doesn’t cut it. If you want to win, you’ve got to prioritise speed and adaptability.

Platform engineering, much like F1, operates in a high-pressure, high-speed environment. The demand for continuous integration, continuous deployment (CI/CD), and fast iteration cycles mean that platform teams need to design systems that are not only stable but also capable of supporting rapid changes and scaling without delay. In modern businesses, the ability to release software updates quickly and reliably is crucial to staying competitive.

Platform engineers must continuously improve infrastructure, deployment pipelines, and observability tools to keep everything running at top speed. This has gotten increasingly complex as the cloud-native computing landscape is a lot to take in!

Platform teams need to choose the right tooling and figure out how best to create toolchains that work. Source: 

Why “Slow and Steady” Fails in Platform Engineering

Platform engineers must keep up with the fast-moving technological landscape. With rapid innovations in cloud computing, DevOps practices, and container orchestration, moving slowly risks falling behind. Those who aren’t constantly improving their platforms may be overtaken by competitors with more agile, modern systems.

They need to solve problems in real-time. Quick responses are essential, whether it's handling unexpected traffic spikes, mitigating security vulnerabilities, or fixing failed deployments. Slow responses in either environment can lead to catastrophic results, whether that’s a car retiring from the race or an outage that costs a company millions in lost revenue.

Every experience offers new lessons, and teams must adjust accordingly. Platform engineering operates under the ethos of 

. Static systems that evolve slowly will eventually struggle under new demands. Continuous delivery pipelines, automated testing, and infrastructure as code help engineers maintain the pace needed to deliver value quickly and consistently.

The most effective systems are those optimised for high performance while maintaining control. Platform engineers strive to create systems that can handle high traffic, scale efficiently, and remain reliable under heavy workloads. While a cautious approach may reduce risks, it can also limit opportunities for innovation.

In all these aspects, just as in racing, the key to staying competitive lies in agility, quick decision-making, and a commitment to continuous improvement.

A well-designed technology platform can make a huge difference here - not just for the Platform team but for the entire “pit crew” of your organisation (Infra, Ops, Security, Information Systems, Site Reliability and more). The concept of an internal developer platform is not new. It emerged as a modern way to run engineering teams with elite teams self-building IDPs for around 5 years prior (for example, Spotify, Airbnb).

Build vs Buy: Internal Developer Platforms in the Race for Speed

Platform engineering teams face a critical decision now: should they build an internal developer platform (IDP) from scratch, or should they buy an off-the-shelf solution? Platform engineers must assess which will get them across the finish line faster.

For many teams, the best approach is often a 

. They may start with a bought solution that covers their core needs and then customise or extend it where necessary, combining the best of both worlds.

So, buckle up - slow and steady won’t win this race. 

F1, DevOps & Platform Engineering: Why Slow and Steady Won’t Win the Race

Blue/Green deployment strategies allow you to minimize downtime and reduce risk during application updates. In this article, I will walk you through setting up an Amazon ECS (Elastic Container Service) Service with Blue/Green deployment using AWS CodeDeploy.

This approach ensures that your service remains available while rolling out new application versions. AWS CodeDeploy enables you to deploy new versions of your application without causing downtime. It allows for a gradual shift of traffic from the old version (blue) to the new version (green).

Here is the Overview of a Blue-green deployment:

In the architecture shown above, we use several key AWS services to manage the automated blue-green deployment:

 manages the blue-green deployment process.

 to route traffic between the old and new versions.

 on the Amazon ECS compute platform assigns listeners to direct traffic to the updated ECS application and uses two target groups during the deployment. CodeDeploy also manages rollbacks by redirecting traffic from the new task set back to the original task set if needed.

The following sequence diagram illustrates the key steps in updating Amazon ECS services.

Step 1: Setting Up AWS Identity and Access Management (IAM) Service Roles

To kick off the process, it's essential to set up the required permissions using IAM roles. You will need to create roles for both the ECS task execution and the CodeDeploy service. These roles will allow AWS services to interact with each other securely.

: This role allows ECS to pull container images and publish logs to Amazon CloudWatch.

: This role gives AWS CodeDeploy the necessary permissions to manage your ECS services during a Blue/Green deployment.

, and then select the required services (ECS, CodeDeploy).

Use the AWS Managed PolicyAWSCodeDeployRoleForECS for the IAM role.

Step 2: Creating the Application Load Balancer (ALB)

An Application Load Balancer (ALB) distributes incoming traffic across multiple targets, such as Amazon ECS tasks in this case. The ALB plays a crucial role in Blue/Green deployment by directing traffic between the old (blue) and new (green) versions.

3. Configure the listener to forward HTTP (port 80) or HTTPS (port 443) requests.

4. Choose at least two Availability Zones to ensure high availability.

5. Create a new target group(Target Group 1 — Blue) or use an existing one to register your Blue Version ECS tasks.

The ALB will handle routing during deployment, gradually shifting traffic from the blue version to the green one.

Step 3: Creating the Amazon ECS Task Definition

Next, create an ECS task definition, which is a blueprint describing the containers to run as part of your ECS service. This step involves defining the Docker image, CPU, memory requirements, and networking configuration.

4. Define the container configuration, including:

Container image (e.g., from Amazon ECR or Docker Hub)

Environment variables and logging settings.

For testing purposes, you can use the Nginx Docker image with an HTML file to identify the Blue/Green version.

Let’s use the Docker image sachithram/nginx-blue:latest for the blue version. To perform the blue/green deployment, create a new revision of the task definition, updating only the image tag sachithram/nginx-green:latest for the green version.

5. Once the task definition and revision are created, this configuration will be used to launch containers during the Blue/Green deployment process.

Step 4: Creating the Amazon ECS Service with Blue/Green Deployments

With your task definition ready, the next step is to create an ECS service that uses 

. AWS CodeDeploy will manage the process, ensuring the new version is tested before routing traffic to it fully.

Steps to create the ECS service with Blue/Green deployment:

1. Open the Amazon ECS Console: Go to the 

 and choose the ECS cluster where you want to deploy your service. Let's use a Fargate Type ECS Cluster.
