tl;dr

  • Evolution of AWS services from simple to complex systems
  • Introduction of Amazon Aurora D SQL demonstrating strong consistency in globally distributed systems
  • Time Synchronization as a new fundamental building block for distributed systems
  • Six principles for managing complexity: evolvability, decomposition, organizational alignment, cell-based architecture, predictable design, automation
  • Demonstration of complexity management through microservices and cell-based architecture
