Migration to the Cloud, DevOps Perspective
summary
Describes migrating from EC2 instances to managed services and serverless functions to cut costs and ops work — e.g., a component’s unit cost dropped from $19 to $0.07, dozens of c5.xlarge servers and Cisco gear were replaced by cloud transit and managed services to save hundreds of thousands in monthly TCO. Concrete examples: replacing bastions with AWS Systems Manager, running Jenkins on Fargate for ephemeral jobs, and a nightly “terminator” function that stops unused instances to save ~12 hours of runtime, while noting risks like vendor lock‑in, function limits, and secrets exposure.
