FAQ
1. What is the difference between composable architecture and microservices?
Composable architecture is a broader strategic framework that encompasses microservices as one potential implementation approach. While microservices focus specifically on application architecture patterns for breaking down software into small, independently deployable services, composable architecture extends beyond software to include business capabilities, organizational structures, and technology selection principles. Composable architecture emphasizes business-centric modularity and may incorporate various technical patterns, including but not limited to microservices, serverless functions, and packaged business capabilities (PBCs). The key distinction is that composable architecture provides a comprehensive framework for building modular systems aligned with business needs, while microservices represent one technical approach to service decomposition.
2. How long does it typically take to implement a composable architecture framework?
Implementing a composable architecture framework is an evolutionary journey rather than a one-time project, with timelines varying significantly based on organizational size, complexity, and existing technology landscape. Most organizations adopt an incremental approach, beginning with a specific business domain or capability and expanding over time.
