Flagship Application Migration to AWS Leveraging Cloud-Native Technology and DevOps Best-Practices

“Risk Focus delivered excellent technical staff with deep knowledge of and insight into the operations and applications of Amazon Web Services, and strong governance and oversight of projects with effective use of AGILE methodologies. The Risk Focus team was able to quickly understand the complexity of our on-prem environment and apply their experience with other customers to guide our solution. Most importantly, the Risk Focus team created a strong partnership with my team to deliver the project.”

The Client: A market-leading fund administrator with global presences and over $1 Trillion in AUM.

The Challenge

The Client’s flagship application had grown unwieldy due to a deeply layered architecture, the result of multiple generations of development. The Client was also looking to exit their data centers and wanted to use this as a catalyst to re-architect the applications and implement DevOps best practices. After initially failing with two other PS firms, this leading Financial Services provider engaged Risk Focus to take-over and complete the migration of their flagship product to AWS.

The Solution

Risk Focus helped the client by:

  • Introducing good development and release processes, increasing velocity and reliability
  • Introducing build and release automation, increasing reliability and repeatability
  • Introducing on-demand environments, decreasing cost
  • Rearchitecting the Flagship app, increasing flexibility

Release frequently requires automation, as there is no time for long, error-prone manual processes. Risk Focus specializes in identifying and opening bottlenecks with a combination of technology introduction and process coaching. Prior to their migration, many of the processes for the client were time-intensive, manual, and error-prone. This led to severe contention in areas such as test environments for QA processes, where new application releases were bottlenecked by the availability of these environments. Additionally, though the implementation was technical, the base application of the firm supports back office processes for hedge funds. Strong domain knowledge derived from building similar trading and risk systems at some of the largest banks and exchanges in the world guided Risk Focus in designs of architecture and recovery processes.

For this client, Risk Focus:

  • Introduced CI/CD pipelines for both applications and the infrastructure components such as networking and VPC on which applications depended.
  • Worked with the client to design and implement customer onboarding automation using DynamoDB and Lambda.
  • Used CloudFormation templates and CodePipeline to create On-Demand environments for QA processes, automating the process of creating and destroying test environments as needed.

The solution relied on CodePipeline, CodeBuild, and CodeDeploy, with code stored in CodeCommit to create the pipelines.

Migrating to the cloud is most effective when combined with application refactor. One of the key victories of the client’s migration to AWS was an update to the architecture of their application.

Risk Focus assisted the client with:

  • Migrating their core application from a monolithic Java application in WebSphere backed by an Oracle store to a micro-services framework.
  • Designing a complete multi-region DR solution, effectively lowering their exposure to unforeseen regional events.
  • The services are run in Docker containers on ECS in AWS, with a managed-services backend running on a set of Postgres RDS databases.

The Benefits

Risk Focus’s work has substantially increased the client’s efficiency by introducing automation in numerous areas.

  • The newly introduced pipelines allowed the client to migrate from an arduous build process on a developer’s laptop to continuous integration complete with an automated test framework built into the deployment pipeline.
  • Automating onboarding has replaced a manual, error-prone system that took weeks with an automated system where the heavy lifting was complete in minutes.
  • Automating QA has not only allowed the client to remove the bottleneck in creating test environments, it has allowed for much more efficient resource management for a significant cost savings. When combined with automated tests, the weeks-long testing cycle was reduced to days. Risk Focus continues to work with the client to shrink that cycle from days to hours, as the legacy manual validation are increasingly captured in automation.

In the end, the client has achieved their key goals. Their application is onboarding customers, their team is moving forward at a greater velocity, and their lead time to release new features is starting to shrink dramatically. The client continues to move forward aggressively in their adoption of AWS. Risk Focus remains engaged with this client, continuing to provide guidance and focused technical deliverables.
