Brittle

Scenario 2: Real-time User Interactivity

Obvious Solution: Read-after-Write

Reality

Distributed Systems 101

Decentralization

Elastic (Join)

Elastic (Leave)

Recover from Failures

Availability through Replication

Event and Message Driven Programming

Properties of Messages

Messaging Patterns

Messaging Protocols

Gossip: How Nodes Discover Each Other

Stateful Application Programming

Stateful Apps Serve Results from Memory

Fastest Response Time?

State Locality

State Makes Protocols Work

CAP Theorem

CAP Trade-offs

Highest Consistency?

Consistency vs. Availability

Fault and Resource Isolation with Microservices

WebCrawler Microservices

WebCrawler Network Topology

Try to make CPU / Memory- intensive tasks into stateless services

Stateful services should increase CPU / memory utilization slowly
