The past decade has seen cloud and infrastructure as code move out of shadow IT and startups
and into the mainstream. Many organizations rushed to adopt new technologies as part of their
transformation into digital businesses creating a sprawl of unmaintainable infrastructure
codebases. Now there is a need to consolidate cloud-based systems into mature foundations for
sustainable growth. With this book Kief Morris describes patterns and practices for building
and evolving infrastructure as code. The third edition provides a broader context for
infrastructure explaining how to design and implement infrastructure to better support the
strategic goals and challenges of an organization such as supporting growth while better
managing costs. This book covers: Foundational concepts including an exploration of
declarative and procedural infrastructure languages where infrastructure code fits into a
comprehensive platform strategy and enterprise architecture and how to test and deliver
infrastructure code. Infrastructure architecture drawing on lessons learned from software
design and engineering to build infrastructure codebases that can be evolved and scaled to
enable growth and adapt to changing needs. Patterns for building infrastructure to support
platform services across the complicated varied landscapes of real-world IT systems from
physical hardware to virtual servers to cloud-native clusters and serverless workloads.
Workflows and operating models that combine automation and cloud with forward-thinking
approaches like Agile and DevOps for rigorous governance of compliance cost security and
operational quality.
