Virtual Machine automatically creating Cloud service in azure manage portal

Question

Hi,

Whenever we create virtual machine in azure management portal, it automatically create a cloud service of same name as that of VM name. So, is it mandatory for us to have cloud service, if we want to create any VM in Azure Manage portal.

Thanks and Regards,

Answer 1

Cloud service is way to communicate with your VM in Azure. Without it you wouldn't be bale to RDP or access any resouce on VM (IIS,SQL...)

You don't have to create new service everytime, you can select option to use existing service.

But yes, you have to have service assigned to VM. You can find more here:

Yes, virtual machine must be part of a cloud service.

Let me explain more:

There are two deployment stacks on Azure :

• Azure Service Management Stack (V1) which is the default classic stack. This stack requires that each VM belongs to a cloud service.
• Azure resource Management stack: This is the new (V2) deployment stack, and will be the default on  the future. Cloud Services are not longer needed and a VM will just be part of what we call a resource group. This simplify the end to end life-cycle of resources and give access to new Features like RBAC

The classic portal (manage.windowsAzure.com) give the possibility to only create V1 resources. The new preview portal (Portal.azure.com) lets you choose between both stacks when deploying a VM.

Look here for more information

Even if the new deployment stack is way better, many features like Backup, ASR and Express Route are not yet supported. So, you have the choice to start today using the new stack or wait until its maturity.
