Immutable Infrastructure Patterns Using AWS Image Builder and Packer

In cloud environments—especially those subject to strict regulatory frameworks like HIPAA, PCI-DSS, or FedRAMP—building consistent, hardened, and auditable infrastructure is not just a best practice; it’s a necessity. One of the most effective ways to achieve this is by embracing immutable infrastructure patterns. Rather than updating servers in place and risking configuration drift or non-compliance, immutable infrastructure treats each system image as a single-use artifact. Every time an application or configuration changes, a new, verified image is created and deployed.
