Rearchitecting
Rearchitecting is the process of redesigning the fundamental structure of a system’s architecture to meet new requirements or constraints. It focuses on how components interact, how data flows, and how deployment is organized, rather than merely changing internal code. Rearchitecting can apply to software applications, information systems, networks, and enterprise architectures, and it often involves changing the technology stack, interfaces, data models, and governance to achieve goals such as scalability, reliability, security, or maintainability, while preserving external behavior where possible.
It is distinct from refactoring, which reorganizes code without altering external interfaces, and from full system
The process usually involves assessment of current architecture, definition of a target architecture, and a migration
Expected outcomes include improved scalability, resilience, and maintainability, along with increased deployment velocity and adaptability to
