Question 4

SoA vs micro-services

Answer 4

The difference is scope: SOA for enterprise-wide and micro-services for applications.

The 2 are compatible.

1- Re-use: SOA wants it for efficiency but m-s may prefer code duplication for agility for decoupling

2- Synchronous calls: SOA wants them but m-s prefer asynch (like event push) for decoupling

3- Data duplication: SOA wants all app to go update data at its primary source, m-s all have the data they need to be independent, even if duplicated
