Amazon S3: SDK or REST API [closed]

Answer 1

If you already have the SDK in your language, go for it; it's a no-brainer from a project perspective. The SDK is additional engineering that they have already done and tested for you at no additional cost. In other words, the SDK is already converting the HTTP REST API into the application domain/language for you.

Think of the REST API as a the lowest common denominator that AWS must support and that the SDK (likely) as implementing the REST API below it. In some cases (eg: some Windows Azure SDKs), the SDKs are actually more efficient because they switch to a TCP based communications channel instead of REST (which is TCP plus HTTP), which eliminate some of the HTTP overhead

Unless your entire goal is to spend additional time (development + testing) just to learn the underlying REST API, I'd vote SDK.

Answer 2

In my own Opinion the API gives you room to do whatever you like.it also helps if you plan on changing a cloud service in the future but if the sdk approach is used, you will have to code again as your app will require a change and the SDK is embedded within your app. I know the response is late but it might help someone.
