X axis scaling

Y axis scaling

Z axis scaling

Microservices

Easier to scale developmentIncreases faultoranceEliminate long term association with technology stack

DrawbacksComplexity of creating distributed system

Deployment complexityAdditional memory consumption

How to partition By verb or use caseBy nouns or resources
