When you create your Azure account, Azure sets default service limits on certain resources on a per-region basis. Before deploying VMs, check the limits to determine if any should be increased especially for core, networking, and storage. Plan to request limit increases in advance of the time that you need them. See Azure Documentation Center.
To request limit increases, create an Azure support request. See Azure Documentation Center. When you create a support request, select the issue type which is always Quota, your subscription, support plan, severity, deployment model which is Resource Manager, location which is your region, specify VMs that apply to this request, and complete the following in the table listed below.
| Request Type | Quota Type | Details |
|---|---|---|
| Cores | Cores | Request the number of additional cores. |
| Networking Limits | Networking: ARM | Request the number of additional public IPs and specify the region where they are needed. |
| Storage | Storage: ARM | Request the number of additional premium storage accounts and specify the region where they are needed. |
