Solution Lifecycle

Because DevOps and DevSecOps span the entire solution lifecycle, the establishment of a unified terminology across development, operations, and security teams is mandatory to ensure operational alignment. This chapter delivers the foundational framework required to navigate and integrate these cross-functional workflows successfully. You’ll master the facilities that prevent system failures, exploring why toolsets like CMDB, DML, and SCM are your single sources of truth. You’ll trace how a solution travels from the safety of the Lab environment, through Test and Pre-Prod, directly into Production environments. Finally, by blending core concepts from ITIL, PDCA, and Six Sigma (DMAIC), you’ll learn to structure security tiers and lifecycles from initial design to final decommissioning. This framework moves beyond mere administrative compliance, providing the comprehensive operational governance required to build resilient, stable, and production-grade architectures.
