Finally, and I love the simplicity of the API. Can't wait to play with it; though I'd have loved to see modern C++ futures to have been used, given that it was just released. But even then, finally there is at least something!

  At least in the following file, all *Callable functions return a future: https://github.com/awslabs/aws-sdk-cpp/blob/master/aws-cpp-sdk-s3/include/aws/s3/S3Client.h https://github.com/awslabs/aws-sdk-cpp/blob/master/aws-cpp-s...

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?
- bananaoomarang 11y ago
  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.
  - nathankunicki 11y ago
    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.
    - oomkiller 11y ago
      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
        monksy 11y ago
        WADL is an description language for REST services.
      - michaelmior 11y ago
        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."
  - techdragon 11y ago
    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 :-/
  - lostcolony 11y ago
    Post it through the API gateway into a lambda function, validate it, and then store it.

Is this auto-generated ?
- wging 11y ago
  Most likely, given this quote at the end: > We also are adding support for individual services as we become more confident that the client generator can properly support each protocol.
- Slippery_John 11y ago
  Yes. I'm pretty sure most if not all of the official AWS SDKs are, with only a bit of hand-coded parts tossed in

  high-score tables, state for online turn-based games, hosting user-generated maps, auto-update system, etc
- justinhj 11y ago
  As a mobile game developer we use a lot of different aws functionality. We don't use c++ a lot though. Console games do so this will probably be used by those although most aws access is done through a server not directly from the client
eigenbom 11y ago
I can see so much potential for this. For example, if you don't want to solely distribute on Steam but want an auto-update feature then it'll be a lot easier with AWS. Not C++ specific, but I'm hopeful that we'll see some game distribution platforms built on top of this kind of tech. More competitors to Steam will be a good thing.
