Evolutionary Serverless Architecture

A system architecture often struggles to adapt to new requirements. Serverless architectures can evolve over time because we can replace the building blocks at any time.

5. 5 ▰ Incremental change ▰ Fitness functions ▰ Appropriate coupling
6. Hi, marbot here! I’m a Slack bot supporting your DevOps team to detect and solve incidents on AWS. 6
7. Why marbot? ▰ smart escalation algorithm minimizes distraction and response time ▰ configures AWS monitoring for you ▰ fun and easy to use chatbot ▰ contextual help to resolve AWS incidents 7
9. Fitness function ƒ: X→figure of merit 9
10. Key fitness functions ▰ Never lose alerts ▰ End user latency < 200 ms ▰ Code coverage > 80 % ▰ Monitoring coverage > 90 % ▰ Managed over self-managed 10
11. Architecture 11
12. 12 Diagrams powered by:
13. Key fitness functions ▰ • Never lose alerts ▰ • End user latency < 200 ms ▰ • Code coverage > 80 % ▰ • Monitoring coverage > 90 % ▰ • Managed over self-managed 13
15. Key fitness functions ▰ • Never lose alerts ▰ • End user latency < 200 ms ▰ • Code coverage > 80 % ▰ • Monitoring coverage > 90 % ▰ • Managed over self-managed 15

18. Summary 18
19. Start as simple as possible ▰ Automate deployment ▰ Use small managed building blocks ▰ Add monitoring/tracking everywhere ▰ Don’t optimize 19
20. Evolve the architecture over time ▰ Analyze monitoring/tracking data ▰ Optimize where necessary ▰ Decouple (e.g. with Step Functions) 20
21. Other learnings ▰ Step functions are awesome timers ▰ User interaction with step functions is ugly ▰ Idempotent state transitions ▰ Remote calls need retry logic 21
