Can we use Openstack Identity API to Create Single Sign on for web Application. If it is possible can somebody give an idea where to start. Like how to get started with Identity API.
You can, but why bother? There are so many other standards and libraries that would do a better job.

I've started to learn backend development, focus on http server mainly.
But I'm really new to this, so it's a little out of focus for me, and I could really use some advice.
For example, if I try to implement something like this
A http server runs on linux/Windows
A private REST API which allows to POST a json object, plus a login mechanism, so only authorised user can do the POST.
Implement a public REST API which allows to GET the same json object
And here is my question:
Can I use Nodejs and express to implement all these? I also know little about them.
Do I need a Database to implement the login mechanism?
Is there any similar tutorial or best practise I can study from?
Regards
Ben
Yes, you can use NodeJS for this.
Not necessarily. You just need a way to authorise users. Most common is to use a database to store a username/email and password, but you could also look into using a third-party service for this, for example facebook or google
Yes, there is a lot of tutorials and especially best practices on this subject. Your question is too broad to link relevant material, but some terms you can use to google this yourself is "nodejs rest api" "rest api best practice". Passport.js is a good place to start for getting into authorising users. For REST-api, the closer you get to normal web standards, the better - Especially if other people than you are going to consume the api.
Node.js is a run-time environment/framework/platform for developing non-blocking I/O server side processes, services, or RESTful API's. You can start by learning what Node.js can do before you go on developing a login story and, and a restful endpoint here
Next if you intend to go all the way and learn full-stack web development start from here, This will guide you to learn Node.js , Express.js, Mongodb, and finally Angular.js for front-end. Good luck and happy coding
Yes, you can use Node.js and Express.js. I recomend you to read some articles about REST and TDD from this amazing blog, especialy this or this.
We have project developed in Silverlight/DevForce services, currently we plain to move code into HTML5. My question is it possible to reuse server side part of project, I means is it possible to reuse DevForce services or better migrate to WebAPI services? IdeaBlade has Breeze Js for HTML5, but it looks more as dataservice provider and not support DevForce services.
You might be asking whether BreezeJS offers a mechanism for handling arbitrary service calls between the client and the Web API running on the server ... in the manner of the DevForce "invokeServerMethod".
BreezeJS does not . The DevForce "invokeServerMethod" is helpful when you need to talk to the server for non-data reasons. You don't have to open and secure your own channel; instead you can share the DevForce secure data channel between client and server. It's also a convenient way to sent a package of entities. Setting up your own independent channel is not much fun.
But writing and communicating with a Web API service endpoint is much easier. Our thought is that you can manage your non-data communications quite well without the help of the BreezeJS EntityManager. So we don't see the need to implement the equivalent of "invokeServerMethod"
However, perhaps you have a scenario that would cause us to reconsider. We'd love to learn more.
Breeze doesn't integrate with DevForce today. I'd recommend adding the request to the Breeze UserVoice site. The Breeze team uses UserVoice to judge interest when incorporating new features.
A quick look shows me that there is already one DevForce related suggestion there: Support for DevForce models.
I need to create a webservice that will be used in iOS, Windows Phone and Android apps.
I've found many tutorials on the Internet but no one uses real JSON files.
I have an example of what I mean:
https://api.twitter.com/1/statuses/user_timeline.json?include_entities=true&include_rts=true&screen_name=tiste&count=2
Is it better to use a web service like Twitter or can we use only headers in PHP?
If it's the first, how can I do it?
Finally, is JSON the most suitable option for web service communication?
Most contemporary web apps are built around an api - they are called api-centric. Twitter is one of them. You are not the only one who needs to create a web frontend and apps for mobile platforms. Having an api for all those platforms is going to save you a lot of time.
This field is developing rapidly now. There are many frameworks(both client and server side) to choose from. Since you are not telling us which technology/programming language you are going to use, i can only suggest you to google an api-centric or a rest framework. If you extend your question, i'll give a more specific answer.
Meanwhile you can read the following general articles...

Does anyone know of any publicly available RESTful services that can be used for testing. I'm not talking about software or browsers extensions. Just an online service that I can CRUD json data with using javascript. I'm testing a JS library's rest api and there's only so much I can do with static json data.
I'm guessing there's no such thing due to what's involved but I thought I would ask.
if you just want to practice 'gets' you can use cloudant as you can sign up for free. however, there are restrictions on adding new documents from a cross domain ajax call. I recommend running one locally. I use couchDB very quick, very easy.
You can use the google feed api and pass in any rss url to test .
This may help you.

I want to build a WCF Server with MySQL Database which can communicate with differents Clients on differents OS. Is that Possible?
if Yes, how should i go? any tutorials which can help me?
Cheers
Is that Possible?
Yes, interoperability was one of the main concerns of the WCF designers.
how should i go?
There are so many options you need to consider, for example security, reliability...
But mainly basicHttpBinding is probably the most interoperable SOAP-based binding. Just google for samples of basicHttpBinding.
On another account, the most interoperable WCF approach is WCF REST which can allow use of JSON that any client can understand, even the browser. However, implementation of WCF REST has quite a few design problems (outside scope of this question) and I would suggest using ASP NET MVC to implement passing JSON objects over HTTP. For security, you can use HTTPS.
