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)

https://github.com/Netflix/EVCache

lessons:

separate real time from batch

Variance

Change

Dealing with incidents

Incident -> Resolution -> Review -> remediation -> Analysis -> Best practice -> Automation -> Adoption

Production Readiness Reviews

  • Alerts
  • Automated Canary Analysis
  • Auto Scaling
  • Chaos
  • Consistent Naming
  • ELB Config
  • HealthChecks
  • Immutable Machine Images
  • Squeeze Testing - uwt is this ?
  • Timeout, retries, fall back, circuit breaker
