I am beginner in ROR. I am working on one project. I want to know the better option between for deployment of the app.
My answer will be more conceptual, rather then technical.
This is the first time I hear about Google App Engine in case of Rails. This is mostly a crucial reason, why I would say, that you definitely better go with Heroku.
While you are a beginner, it's better to use the most widely spread solutions and tools. Heroku has a huge history and you can find any answers in the internet very easily. It's well known among rails community and everyone can make a small consultation according to it.
Even if Google App Engine would be better or cheaper (haven't checked it), you shouldn't start such experiments until you have good deploy/rails knowledge.

Which one is the most reliable and the most scalable?
ActionCable or Socket.io?
In order to avoid the opinion based answers please provide some real measured data which prove the hypothesis.
Are there any apps out there in production which were implemented using ActionCable, since ActionCable is out for a year?
Thx
If you are using Rails, ActionCable will be fine. It is currently used on Basecamp and powers their chat and notification features.
This is a large scale application with heaps of daily active users so really you shouldn't be worried about scale. However, if you are talking about millions and millions of active connections, then probably neither is your best option - with the better alternative being Elixir/Erlang (2Million Websocket connections in Phoenix) or even NodeJS.
However in your case if you are using a Rails application, then Actioncable is going to be much easier to implement as it is a feature of Rails and not an external party.

I'm currently developing a rails app, based on Redmine, using a multitenancy approach. The app it is intended to be used by lots of users (at least I hope so :)), so it is important that it can handle several requests without compromise its performance. Having this in mind, I'm wondering which rails server would suit my needs best. I'm currently using thin, for memory savings purposes, but I'm afraid it is not the best choice for me... I've used unicorn before and I liked it a lot, but it was consuming a lot of memory and I had to change it to another one, but I've noticed that my app is not as fast as it used to be. Any advises? Thanks a lot in advance!
Use Passenger with Apache.

Can Ruby on Rails be used for developing Real Time Application (similar to like Facebook, twitter, geekList ) ? What sort of database (NoSql), REST API is required ? Node.js seems to be popular for RTA. Any insight will be greatly appreciated?
You can try with Faye, but if you want development real time application, I think Node.js is the best. :)...Sorry, I'm only beginner developer :)
Ruby and Rails can definitely be used for that (twitter was originally a Rails app). What kind of db you need will depend on the specifics of your application. I am guessing from your question that you are a beginner. In that case, I would guess this is one of your first applications and you are trying to figure out which technology to you. I suggest you pick whichever one you are most interested in. You can do the kind of application you are talking about in most modern web frameworks.

I am a beginner at web development and wanted to know where to begin when developing a web application. More specifically I am using RoR and wanted to know is there a particular stack developers start with for instance would it be better to start developing models or views? Or do I have the wrong approach all together.
This will guide you through installation and 'hello world' in rails.
http://guides.rubyonrails.org/getting_started.html
And I highly recommend this book, if you are serious about rails. Finish it completely. It would give you insights which might take months to comprehend if you are searching only in web.

Rails sort of has two "default" stacks, as this blog post helpfully explains:
http://words.steveklabnik.com/rails-has-two-default-stacks
You'll see that mr. Klabnik also has some thoughts about the difficulty this creates for new developers. I'd recommend not worrying too much about all the different tools that are available to you at first. Wait until you have a problem or are experiencing some pain and then find a tool to solve that problem. Before that, just jump in and learn as you go. Or at least, that's how I'd approach it, but people learn differently!
