The Service-Based Architecture Paradigm

When To Use

• Multi-team organizations with domain-aligned services
• Systems requiring independent deployment of components

When NOT To Use

• Single-team projects small enough for a monolith
• Latency-sensitive systems where inter-service calls are prohibitive

When to Employ This Paradigm

• When teams require a degree of deployment independence but are not yet prepared for the complexity of managing numerous microservices.
• When shared databases or large-scale systems (like ERPs) make full service autonomy unrealistic.
• When establishing clear service contracts for partner teams or external consumers.

Adoption Steps

1. Group Capabilities: Bundle related business functions into a small set of well-defined services, each with a designated owner.
