Challenge
Legacy payment applications needed to move from FIS-hosted environments to AWS while modernizing how infrastructure was provisioned and applications were deployed.
My contribution
I worked on application migration and cloud modernization using AWS, ECS, Kubernetes, and Terraform. My contribution connected the migration effort with repeatable infrastructure provisioning and deployment practices.
System overview
The modernization brought legacy workloads into an AWS environment using container platforms and infrastructure as code. ECS and Kubernetes were part of the platform toolkit, while Terraform described infrastructure in version-controlled configuration.
Text description: legacy payment workloads transition to AWS container platforms. ECS and Kubernetes represent the platform options in the project; Terraform supports provisioning the AWS infrastructure.
Outcomes
The modernization effort delivered 60% less deployment time and 40% fewer audit-detected vulnerabilities.
Engineering considerations
Moving an application and improving its release process are related tasks. Infrastructure definitions can make environments reproducible, but a migration also needs explicit dependency mapping, application validation, and recovery planning. Those considerations should guide the sequence of changes rather than assuming that a container migration alone resolves operational risk.
