Steps for a successful migration to Red Hat OpenShift Service on AWS (ROSA)

Enterprises have an abundance of options when considering their long-term modernization and container strategies. With constant innovation and associated change in this maturing space, it is important to choose a path wisely and to strive for consistency and predictability to maximize what really matters most at the end of the day, business value. As enterprises look to optimize their Kubernetes strategies, Red Hat OpenShift quickly emerges as a leading platform to build upon for a variety of reasons. Aligning containerization benefits with enterprise cloud strategies brings forth another no-brainer in leveraging the market leader, Amazon Web Services (AWS), to drive the ultimate combination of flexibility, scalability, and simplicity, which are historically uncommon attributes when referencing enterprise platform architecture.

AWS and Red Hat have been collaborating for years to drive innovative solutions in the rapidly evolving space of enterprise technology. The latest release of Red Hat OpenShift Service on AWS (ROSA) combines the best of both worlds to accelerate application modernization with native streamlined efficiencies that enterprises are seeking in today’s increasingly complex enterprise architecture space. For customers looking to embrace the business benefits that ROSA introduces, it is important to map

out a winning strategy to ensure a successful migration. Here are 5 key considerations to consider when planning your ROSA migration.

1) Infrastructure and Platform Analysis

· Ensure you have complete visibility of your legacy platform for all applications. Leave no stone unturned.

· Identify and plan for all platform gaps and application dependencies.

· Map functionalities to OpenShift early in the process.

2) Application Analysis

· Catalog all critical applications with key attributes such as internal and external dependencies, underlying language, and framework (with versions).

3) CI/CD Analysis

· Validate the accuracy of your current pipeline process from a build, dev, release, prod, and validation perspective.

· Adapt pipeline stages to leverage OpenShift standards like Helm and OpenShift Operators.

· Plan for future native pipelines including Tekton.

4) Code Automation Analysis

· Analyze code for trends to remove and replace or update code as needed.

· Consistently feed your tooling to drive measurable improvement with each application.

· Slow down to speed up, embrace automation at every possible step.

5) Plan for optimization

· Embrace OpenShift’s simplified options for automation and governance as code.

· ROSA allows for management though the familiar OpenShift interfaces, with simple integration to a growing list of cutting-edge AWS services.

· Identify and plan for the art of the possible once you have reached your destination.

Focus on accelerating simple use cases as a first step. Lean on the experts from AWS, Red Hat and their partner ecosystems to help ensure your migration is a success that clearly articulates the associated business value. It is important to include assumed benefits that ROSA also represents with greater ability to focus on innovation and business value by leaving the management and support burden up to the experts at Red Hat and AWS. ROSA introduces a low friction, streamlined platform that will uncover areas of efficiency that are unique to each customer and opens endless possibilities for ongoing focus on modernization and innovation.
