Traffic, a good problem to have

  • Picnik stores a lot of temporary files

5. Flash Security model used to require our Client SWF to proxy through our servers 6. Store images in case user accidently closes browser 7. Store images and changes for rendering saved images 8. Picnik has Perfect Memory! 9. For Registered and Premium users, Picnik maintains a history of all edits 10. Thumbnails 11. Data Center backups 12. Started with our own storage, quickly outgrew our capacity 13. S3 to the rescue 14. Local Storage for short lived objects 15. S3 for long term storage and emergenciesS3? Picnik stores files?
16. Picniks architecture allowed easy expansion into EC2
Our DC was already virtualized with XEN
Image rendering could easily be moved to EC2
With EC2 we could easily shift the mix of servers in our DC
0-100% of our Rendering can be sent to EC2
Daily peeks are handled transparently
Auto-scaling ramps up our EC2 use when needed
EC2 == Flexibility
17. Our Local storage went down for 12 hours, almost no down time as we shifted to S3
Dev time constraints limited some optimization work with our storage, S3 gave us time (months!) to solve the problem
EC2 Capacity provided relief for unexpected events (our own bugs, partner hiccups)
