Immutable infrastructure is an approach in DevOps that emphasizes replacing servers rather than patching them, leading to predictable deployments and easier rollbacks. While it has many benefits, such as reducing configuration drift and enforcing best practices, there are challenges like slower deployment times and the need for upfront complexity in automation. Organizations should consider a gradual migration strategy to embrace immutable infrastructure while managing existing legacy systems.

GitOps has become a crucial standard for managing cloud-native applications by leveraging Git as the single source of truth for system configurations, enabling faster, safer, and more consistent deployments. The article discusses the evolution of deployment methods, the advantages of GitOps over traditional practices, and the tools available in the GitOps ecosystem, highlighting the increasing adoption of both pull-based and push-based models in modern software operations.
