Recently, I was experimenting with moving local TeamCity Build Server and Agents to the Azure. Every time I created a VM, I was faced with the question of creating a new cloud service or using an existing one. I simply went with creating a new one, until I needed to perform Azure Scaling. Then i came to know, it is easier to do that when VM’s are part of the same cloud service.
The question that kept bugging me was, how does the traditional cloud service (the one with worker and web role and 2 instances) relate to a cloud service that has many VM’s for the purpose of scaling and load balancing? Ultimately, aren’t cloud services and VM’s separate things?
The article by Planky at MSDN Blogs answers these two questions it in detail.
