Explains isolation, service contracts, incremental extraction, and rewrite trade-offs without detailing domain-modeling techniques.

Domain

As explained in Google Anthos in Action

A business domain is a bounded area of business knowledge, rules, data, and capabilities addressed by software.

A business domain is a focused area of business capability that can be separated from a legacy application and implemented as an independently developed service. Clear boundaries and well-known contracts limit the impact of changes on dependent services. section 16.1

Use domain boundaries to:

Build and test one business capability in isolation for faster iteration. section 16.1
Extract capabilities incrementally instead of rewriting the entire application when investment and business goals favor a gradual transition. section 16.1
Start modernization with edge capabilities such as authentication, authorization, or logging. section 16.1

Incremental extraction

Separate an authentication capability from a legacy application, expose it through a well-known contract, and operate it as a cloud-native service while other capabilities remain in the monolith. section 16.1
