Cloud Migration and Security Operations

I delivered cloud migration projects for large enterprise customers during an 8-month project to build a multi-account AWS environment to host 100+ applications.

I enabled a cloud environment set up using AWS Landing Zone to ensure the account and environment have a consistent set up. I then helped set up security controls and operations capabilities to ensure safe and smooth operations of the cloud.

Cloud KPIs were set up with well-architect pillars and the Cloud Adoption Framework. Once the application was moved to AWS cloud, it was measured against the KPIs for successful implementation. The cloud worked as expected, and applications were then moved to the cloud by validating against the KPIs.
