My application contains 25 C# projects, these projects are divided into 5 solutions.
Now I want to migrate these projects to run under Windows Azure, I realized that I should create one solution that contains all my web roles and worker roles.
Is this the correct way to do so, or still I can divide my projects into several solution.
The Projects are as shown below:
The most important question is: How many of these 25 projects are actual WebSites/Web Applications or Windows Services, and how many of them are just Class Libraries.
For the Class Libraries, you do not have to convert anything.
Now for the Cloud project(s). You have to decide how many hosted services you will create. You can read my blog post to get familiar with terms like “Hosted Service”, “Role”, “Role Instance”, if you need to.
Once you decided your cloud structure – the number of hosted services and roles per each service, you can create a new solution for each hosted service.
You can also decide that you can host multiple web sites into a single WebRole, which is totally supported and possible, since WebRoles run in full IIS environment since SDK 1.3. You read more about hosting multiple web sites in single web role here and here, and even use the Windows Azure Accelerator for Web Roles.
If you have multiple windows services, or a background worker processes, you can combine them into a single Worker Role, or define a worker role for each separate worker process should you desire separate elasticity for each process, or your worker require a lot of computing power and memory.
UPDATE with regards to question update:
So, the Web Application is clear – it goes to one Web Role. Now for the Windows Services. There are two main considerations that you have to answer in order to find whether to put them into a single or more worker roles:
lot of RAM)?
If the answer for any of the questions is “yes”, then put this Windows Service in a single Worker Role. Put all the Windows Services that the answer for both questions is “no” in a single Worker Role. That means that you will scale all of them or none of them (by manipulating the number of instances).
As for Cloud Service (or the Hosted Service), it is up to you to decide whether to use a single cloud service to deploy all the roles (Web and Workers) or use one Hosted service to deploy the Web Role and another one to deploy the Worker Roles. There is absolutelly no difference from billing prospective. You will still have your Web Role and Worker Role(s), and you will be charged based on instances count and data traffic. And you can independently scale any role (change the number of instances for a particular role) regardless of its deployment (within the same hosted service, or another hosted service).
At the end I suggest that you have single solution per Hosted Service (Cloud Project). So if you decide to have the Web Role and Worker Roles into a single Hosted Service, than you will have a single solution. If you have two Hosted Services (Cloud Projects), you will have two solutions.
Hope this helps.
