PHP and Platform Independance in the Cloud
Download as PPTX, PDF3 likes1,282 views
The document discusses PHP and platform independence in the cloud. It describes different definitions of the cloud and benefits like scalability. It notes that applications should be written for the cloud using cloud services. Moving applications between cloud providers is difficult due to API differences. The PHPilosophy is presented as using abstraction to create common interfaces for cloud services like storage, documents, and queues to provide platform independence when using different cloud providers.

- 7. The Cloud is all around us.On your iPhone. Under your Facebook apps. All up in your twitter account.

- 21. Now You’re ScrewedEvery 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.
