Mastering Chaos - A Netflix Guide to Microservices - Notes
Evolutionary response
- Separation of concern: modularity and encapsulation
- Scalability: horizontal, and partitioning
- Virtualization and Elasticity - automation, and on demand capacity
Dependancy
Use cases:
Intra-Service Requests
can handle non ideal issues
- network issues
- back off
- handling failure.
- can protect against one service failing?
Hystrix
FIT - Fault Injection Testing
Graceful degradation - testing the removal of things, some less important, some more.
Client libraries
Bare bones , or client libraries?
Data persistance
CAP theorem - In the event of a network partition the trade off between consistency and availability.
Infrastructure
Scale Use Cases
Stateless
Stateful
Hybrid
caching layer is hybrid
consider VCache, a system for managing memcache (server) and spymemcached (client)
