Confusion regarding WCF at Azure

Question

I have few WCF services, deployed at IIS, which are consumed by some android devices. I'm have to move all my databases and services to Azure. I googled to find out how to deploy WCF at Azure, and found a concept of WebRole and Azure Cloud Service project. See THIS SO POST

But at the same time, I just tried creating a new webapp in Azure and simply published my WCF services project there, and it worked fine. (I tested with client).

My Question is,

• What is the difference between the methods mentioned in the post I linked, and the way I deployed? I'm concerned, because I'm expecting high amount of requests.

• Is it okay to deploy my already created/ready services the way I did?

• What is preferred?

Answer 1

Both (WebApp and Web role) will work for your scenario.

The main difference between this two way is that Web role allows you to connect to it through remote desktop.

You can keep using WebApp and configure Auto Scaling (based on CPU usage or at a specific time).
