60. Bootstrapping and immutable infrastructure (immutable-image deployments)
Immutable-image deployments to ensure consistent scaling and reduce configuration drift.
Infrastructure as Code / AWS (Terraform & AMI/CloudFormation patterns)
Bootstrapping and immutable infrastructure (immutable-image deployments)
Deploy systems by baking configuration into machine images and replacing servers instead of mutating them in-place.
"I want each new server to be identical and never drift from the tested state."
Immutable-image deployments create a golden image (AMI) with all software/config baked in; autoscaling and updates replace instances with new images rather than changing running machines. This reduces configuration drift and makes scaling and rollbacks predictable.
