Is there any way to implement server push from GAE to c# client? I found channel-api is available only for Javascript applications & also GAE is not supporting comet solutions.
There's not currently any supported mechanism of doing client push to anything other than a Javascript client, unless you use an external service to do it.

I want to deploy a multi-service application on GAE using custom runtimes.
I've everything set, my service expects some environment variable to know when to connect to the database and other services.
But I can't see anywhere in the doc where it explains how to connect to other Google Cloud service from a custom runtime.
If it is explained, thanks for pointing me there. if not, can someone who has been successful on doing that explain to me how he/she achieved it.
The documentation for connecting from Flexible Environment apps is found in Cloud SQL > Documentation > MySQL > Connecting from App Engine. Some of the languages (for example, for python) make use of the Cloud SQL Proxy, while others (such as java) don't.
As for Pub/Sub, you can read about client libraries in the documentation.
We have an IoT project here
Facts:
We have our app running on Google App Engine, PHP runtime.
The clients are raspberry pi or similar boards.
We are using cloudmqtt (www.cloudmqtt.com) to generate a push event on our C client app, which then runs the sync process with the server
Is there a google cloud replacement for what we are doing?
We tried Google Push/Sub, but our C app needed to be polling the service.
We would love to use Google Cloud Messaging but we could not find any way to use it for push notifications for the client.
Basically, we need to send push messages to a raspberry pi, what would you recommend for that? (remember our server is on GAE)
GCM handle polling mechanisms on its own and should let you push notifications as well as messages to the client. Try debugging your application using documentation.
During I/O 2016, they also launched Firebase Cloud Messaging (FCM) which is basically a newer version of GCM, and is the recommended product to use.
But if you wanted to use your deployment rather than a service, you can use Google Compute Engine instances to deploy EMQTTD which is a highly scalable MQTT broker written in Erlang.
I want to write a desktop application that interacts with a GAE-based web service. For Android and Web clients there is the possibility to generate client libraries automatically. Is there a way to generate client libraries for C or C++? I would settle for Python as well.
Theoretically all the Google APIs Client libraries allow accessing any Discovery-based API as long as the discovery document is available (which is the case for cloud endpoints) even though the functionality isn't very well documented in most cases.
See https://developers.google.com/discovery/libraries for a list of currently available client libraries.
As example of how you can use the python client library with cloud endpoints:
service = build("your_api", "your_api_version", http=http,
discoveryServiceUrl=("https://yourapp.appspot.com/_ah/api/discovery/v1/"
"apis/{api}/{apiVersion}/rest"))
result = service.resource().method([parameters]).execute()
Currently, Google App Engine Cloud Endpoints only supports generating client libraries for Android (Java), iOS (Objective-C) and JavaScript. See https://developers.google.com/appengine/docs/java/endpoints/overview.
Of course you may still develop your application using GAE for your web service and write the web service interface libraries yourself in any language you choose.
I'm trying to develop a Windows Phone 8 app. I've created a Web Site in a Windows Azure account which is an MVC 4 project with REST endpoints. I've got an SQL database in Azure to store data from the Azure Web Site. Ocassionaly, I want my application to send PUSH notifications to mobile phones. So I've created a Mobile Service and I've linked the SQL database with the Mobile Service's database in order to have got the same data for the web page and the service.
I though that when I send an HTTP POST to the web site, the script in the database from the Azure Mobile Service would be launched but it looks not to be true. Isn't it? Because of that, I would write in the controller of an HTTP POST endpoint the code to send the data to the Mobile Service endpoint in order to launch the JavaScript code to send the Push Notification.
Is that the right approach for my goal? Is there any way for sending PUSH notifications from an Azure Web Site or it is only allowed from a Mobile Service?
My last question: Do you know any books or blogs about development in Windows Azure? On the Internet there is lots of documentation but principally those are get started tutorials. I've read some books but those are really complex, boring, and not really practical.
As your website MVC4 based and is running on Windows Azure using SQL Database as backend, I will guess that it is based on ASP.NET and i will write my suggestion based on that.
Now about your question "Is there any way for sending PUSH notifications from a Azure Web Site or it is only allowed from a Mobile Service?" I would say, Azure Mobile web services are designed for the same purpose for any service running on Windows Azure to send push notification on multiple of platforms. Application developer can choose to use Mobile Services to expedite their development as well as have multiple application using the one single service for such objective.
However as you mentioned "Is there any way for sending PUSH notifications from a Azure Web Site" this is not depend on "Azure web sites" instead it is depend on what development technology you are using with your Windows Azure Application. For example in ASP.NET your can use SignalR implementation if your application is based on Java, PHP, Python, Node,js etc then you can find some other run time specific real time implementation. If you look around for websockets you will find implementation in almost every popular language or look for comet programming on this regard. Not only that you can use some of the popular 3rd party applications for this purpose as well. i.e. pusher or any other.
While Windows Azure Mobile Services will give you the best results on Windows Azure platform as it is designed to provide such specific functionality for applications running on it.

I have a question surrounding the REST service. I have an application written in C# , i want to put this application onto the cloud. I have a small problem, My Application has a built in C# API. I want to interact with my application and Google app engine. I want to develop a JAVA PROXY on top of GAE so that it can interact with my application using REST protocol and performs CRUD operations on Cloud and returns back data to my application.
Is it possible to do this ? to what i know is that SANDBOX feature doesn't allow us to directly interact with the App Engine.
Any suggestion on this.........
Thanks Heaps

You don't need Java Proxy API in order to make http requests to another server (I guess you did not have java's Proxy class in mind?).
Yes, AppEngine can make HTTP/REST requests to other servers via URL Fetch java API.
