Building Resilient Systems with Immutable Infrastructure on Azure

In modern DevOps and cloud-native architecture, immutable infrastructure has become a best practice for ensuring consistency, security, and reliability. This pattern means that once a virtual machine (VM), container, or other infrastructure component is provisioned, it is never modified. If changes are required (such as a software update or configuration tweak), a new version is built and deployed instead of patching the old one.

In this blog, we’ll explore:

• What the Immutable Infrastructure pattern is
• Benefits of using it
• How to implement it using Azure services
• A sample deployment workflow using Azure DevOps and ARM/Bicep/Terraform
