Transcript

1. True story of re-architecting website for scale on Windows Azure
2. 1,3 billion+ web transactions / day 3 datacenters / 300+ servers
3. Lithuanian-based startup 20K+ unique visitors per month can go viral any day soon
4. HOSTING WINDOWS AZURE website, blog static content database photos Linux | Apache | MySQL | PHP Linux | Nginx | FTP
5. ~260K page views / month ~9K page views / day ~1K page views / hour ~0,2 page views / second 20K+ but spikes up-to 50 page views / second
6. Cloud gives more flexibility and scalability options Windows Azure is Microsoft’s Cloud Platform BizSpark gives Windows Azure for free for 1 year Let’s move!
7. VIRTUAL MACHINE
8. HOSTING WINDOWS AZURE website, blog static content database photos Linux | Apache | MySQL | PHP Linux | Nginx | FTP
9. WINDOWS AZURE website, blog static content database photos Linux | Apache | MySQL | PHP Linux | Nginx | FTP
10. Dedicated VM for storing content is suboptimal in the cloud Manual management & scaling No backups SCALING ISSUE #1
11. BLOB STORAGE
12. WINDOWS AZURE website, blog static content database photos Linux | Apache | MySQL | PHP Linux | Nginx | FTP
13. WINDOWS AZURE website, blog static content database photos Linux | Apache | MySQL | PHP HTTP
14. Static content on the same VM as website and blog Different scalability targets Photos are part of static content SCALING ISSUE #2
15. WINDOWS AZURE website, blog static content database photos Linux | Apache | MySQL | PHP HTTP
16. WINDOWS AZURE website, blog database static content Linux | Apache | MySQL | PHP HTTP
17. Database on the same VM as website and blog Very different scalability targets and strategies SCALING ISSUE #3
18. WINDOWS AZURE website, blog database static content Linux | Apache | MySQL | PHP HTTP
19. WINDOWS AZURE database static content Linux | MySQL HTTP website, blog Linux | Apache | PHP
20. Blog on the same VM as website Different scalability targets SCALING ISSUE #4
21. WEBSITES
22. WINDOWS AZURE database static content Linux | MySQL HTTP website, blog Linux | Apache | PHP
23. WINDOWS AZURE database static content Linux | MySQL HTTP website Linux | Apache | PHP blog IIS | PHP
24. FURTHER SCALING
25. Website gets more requests than can handle SCALING ISSUE #5
26. WINDOWS AZURE database static content Linux | MySQL HTTP website Linux | Apache | PHP blog IIS | PHP
27. WINDOWS AZURE database static content Linux | MySQL HTTP website Linux | Apache | PHP blog IIS | PHP
28. Database gets more queries than can handle SCALING ISSUE #6
29. WINDOWS AZURE database static content Linux | MySQL HTTP website Linux | Apache | PHP blog IIS | PHP
30. WINDOWS AZURE read-only database static content HTTP website Linux | Apache | PHP blog IIS | PHP write-only database Linux | MySQL Linux | MySQL
31. Read-only database gets more queries than can handle SCALING ISSUE #7
32. WINDOWS AZURE read-only database static content HTTP website Linux | Apache | PHP blog IIS | PHP write-only database Linux | MySQL Linux | MySQL
33. WINDOWS AZURE read-only database static content HTTP website Linux | Apache | PHP blog IIS | PHP write-only database Linux | MySQL Linux | MySQL
34. Write-only database gets more queries than can handle SCALING ISSUE #8
35. This is a nice issue to have Split write-only database into shards with multiple read-only slaves for each shard accessed via layer of distributed cache
