Phase 01 of 04

Distributed Systems Fundamentals

Weeks 1-2: Distributed Systems Fundamentals (CAP, Consistency, Consensus, Databases, Messaging).

Weeks 1-2: Focus on core distributed systems concepts. Review topics like CAP theorem, eventual consistency, distributed transactions, consensus algorithms (Paxos, Raft), and common architectural patterns (microservices, event-driven). Study database scaling techniques (sharding, replication) and message queueing systems (Kafka, RabbitMQ).
