On one hand I'm quit surprised this didn't already exist, but on the other hand I can't see a huge market for it?

Games, I would guess would be the market. Though yes it is strange it took so long.

I love C++, so I'm excited. I can imagine non-C++ libraries (e.g. Python or Ruby) wrapping the C++ interface rather than using a custom implementation.

  May I ask why? Plenty of implementations already exist for other languages, and since the interface is just HTTP, I see little benefit to wrapping the C++ library.

    Official, full support, instead of a custom implementation where it can take weeks to add support for a new service that's already a part of the C++ lib. Also, there are some newer languages out there that don't have quality libraries for AWS, but do have C extension support. This will allow wrappers for to be created so these languages can be used with AWS as well. Just take a look at how the Java lib is used.

      In my experience, it's just easier to take their API descriptor file (JSON IIRC) and generate a client from it.

        This is what boto3 does

        Wouldn't that be WADL?
        Slippery_John 11y ago
        No, WADL is XML. You can see some of the data files in the boto3 repository: https://github.com/boto/boto3/tree/develop/boto3/data https://github.com/boto/boto3/tree/develop/boto3/data It is somewhat similar in concept

        WADL is an description language for REST services.

      Given that it is just an HTTP API, I'm not sure it would actually be that much faster to wrap a C++ API than just write a native lib. Plus unless the wrapper is written by Amazon as well, it's not really "official, full support."
    - nathankunicki 11y ago
      I'm still not sure I follow. There are plenty of first-party fully supported SDK's for various languages, eg. Ruby, Node.js, Java, .NET, etc: https://aws.amazon.com/tools/ https://aws.amazon.com/tools/ In fact from personal experience of the Node one the SDK uses the API descriptor to generate the client (Which makes unit testing it tricky incidentally, but I digress).

  I cant. C++ is a pain to wrap. Most good libraries written in C++ that are meant to be used as libraries in other languages expose a C interface. I don't see a C interface in their docs.

Could upload large binary blobs of game state to S3 instead of building your own backend. Though that means having no backend to validate data :-/

  Post it through the API gateway into a lambda function, validate it, and then store it.
