Presentation Transcript

  1. Architecture of infrastructure in cloud

  2. Presentation Structure • Why cloud? • Cloud ready architectures • Cloud services • Disaster recovery • Capacity planning

  3. WHY Cloud?

  4. Why we talk about clouds? • Основная причина – борьба с высокими нагрузками

  5. Classical application evolution Database cache User requests Database server Application server Media content Content server

  6. Key bottlenecks • CPU -> Balancer for app servers, database clustering • RAM -> Clustering or memory consuming components • Network ing-> DNS RR, object storage, CDN • Disk I/O -> database clustering • Ping -> CDN, per-region architecture

  7. Virtual/hardware vscloud

  8. Cloud ready architecture

  9. Cloud architectures - grid

  10. Cloud architectures - Transactional

  11. Cloud services

  12. Cloud services • Object Storage • Compute Instances • Load balancers • CDN • Networking

  13. Object storage • Amazon S3 • Atmos

  14. Compute instance • Amazon EC2

  15. Ephemeral • Sometimes you have no “physical “ access to VM at all

  16. Load balancers • What is it? • How it works? • How it configures?

  17. Monitoring • Cloud Watch • What is it? • How I can use it? • Monitoring + Load balancer

  18. Content Delivery Network • Amazon Cloud Front • Akamai • Etc. • What is it? • Why I should use it? • Where I can use it?

  19. Networking • Public networks • Private networks • Network configuration • Security groups

  20. Disaster recovery

  21. Automation

  22. Monitoring

  23. Disaster-ready architecture

  24. Capacity planning

  25. Dynamic scaling

  26. Pro-Active scaling

  27. Reactive scaling

  28. Why projects moving to cloud? • Cost reduction • Pay as you go • Scalability and elasticity • Ready for automation • Device and location independent • Buzzword

  29. When you cant use cloud? • When you need hardware • When you need high speed I/O (high speed storage) • 100% capacity usage • Barrier to exit (migration to cloud more expensive then classical infrastructure) • Integration with legacy systems • Security concerns
