Microservices

Microservices

Bounded Context
Subdivide monoliths
Small Teams
Independent
Clearly-Defined Interfaces

Conway’s Law

Command (Create, Add, Save, Notify)

the microservice architectural style is an approach to developing a single application as a suite of small services, each running in its own process and communicating with lightweight mechanisms, often an HTTP resource API.

Separation of concerns
Modularity, encapsulation

Scalability
Horizontally scaling
Workload partitioning

Virtualization and elasticity
Automated operations
On demand provisioning

Like the human body
Each organ has a purpose
Organs form systems
Systems form an organism

Use an ELB (elastic Load Balancing)
