20. . . .assuming you chose the right cloud provider.

21. Now You’re Screwed Every API is different! I’m locked in! My cloud provider is bending me over! The sky is falling!

22. Or are you? After all, there’s lots of commonality across cloud application services.

23. Yes, you are. All that commonality is hidden behind uninteresting differences.

24. Porting an AWS Application to Azure Change your signature algorithm ‘buckets’ are now ‘containers’ ‘objects’ are now ‘blobs’ SQS RESTish query API needs to be changed to the RESTful Azure Queue Storage API SimpleDB to Azure Table Storage? Good luck with that.

25. Moving Your Applications is Hard And not for interesting reasons. :-/
