1. Many Layers of Availability how to achieve so many nines in practice 99,99% 99,999%
2. 1. Migrate to microservices 2. ??? 3. PROFIT
3. Ilya Kaznacheev, PhD Cloud-Native App Architect Ex. GDE on Google Cloud 12 years in software engineering
4. So, what about the nines?
5. Application level 1
6. Architecture • independent modules • avoid single point of failure
7. Redundancy • component replication • concurrent computing • resource scaling
8. Load Balancing • request distribution • smart balancing • dynamic scaling
9. Reducing Dependencies • interaction over APIs • eliminating implicit depd. • consolidating features
10. Sync. vs Async. • message-based • event-based
11. application
12. Platform level 2
13. Clusters • preventing outage • load distribution • network replication
14. Orchestration • lifecycle control • autoscaling • anti-af fi nity
15. Self-Healing • machine replacement • health checks (ext) • health monitoring (int)
16. application platform
17. Data level 3
18. Redundancy • database replicas • msg broker replicas • backups
19. Caching • application caching • database caching • standalone caching • content delivery network
20. application platform data
21. Infrastructure level 4
22. Compute • hot migration • instance groups
23. Networking • software de fi ned network • load balancing
24. Disk • replicated storage • network fi le system
25. application platform data infrastructure
26. Hardware level 5
27. Hardware • RAID • rack distribution • internet channel backup
28. application platform data infrastructure hardware
29. Global Availability level 0
30. Cloud and DC • multi DC disaster recovery • cloud multizone regions
31. Global Server Load Balancing • BGP Anycast • multiregion load balancing
32. application platform data infrastructure hardware global availability
33. Summing Up • availability is made up of many levels • each level must cooperate with other levels • need to consider all levels when developing HA systems
