As we know public cloud is offering unlimited* amount of resources and as an end user of public cloud we don’t need to worry about the backend resources. But, there are few facts to consider when we talk about unlimited.
- What if someone run a script to spin up 1000 VMs !
- What if someone give wrong variable and your automation program created 10000 database instances or disks !
- What is some users purposefully created VMs with high in size ?
That’s where we need a governance in place to control the usage of computing resources and to prevent unforeseen spikes in usage. Every public cloud (Private Cloud also) provider is offering this option called Resource Quota, by which, you can control the usage of so called “unlimited” resources.
Also read Resource Quota in Google Cloud Platform (GCP), AWS Service Limits or Azure subscription and service limits, quotas, and constraints
But, what if we reach our resource or quota limit and we need more resources ? No worries, you can request for increasing the quota limit and let’s see how we can do this in Microsoft Azure. IN
From Microsoft Azure console, select Subscriptions
Choose your subscription to manage (Remember to choose the correct one if you have multiple subscriptions)
On the Subscription screen, you can see the usage, cost summary etc. Now, select Usage + Quota tab as shown below.
It will show current Usage and Limit of each resources items in all locations, as show below. Now filter out the resource type you want to see and update quota. Add more filters like Locations etc and see what is the usage and limit for your resources.
Let’s say you want to increase the quota limit for FS Series and FSV2 Series CPU’s in UK South (Europe) region, we can request the same. Find Request Increase button on upper right corner of the window as show below.
It will open a New Support request window; choose issue type as Services and subscription limits (quota), then your subscription and Quota type as Compute-VM as show below.
In the next screen, you have to provide details by cliking Provide details as show below.
Choose quota details for your multiple resources eg: FS Series, FSv2 Series in our case and mention new limit in the input box.
Preview and verify the new quota/limit request in detail screen.
On next screen, choose the severity and contact information.
Review your request and verify all values are good before you submit. A sample screen shown below.
Once created request, limit will be automatically increased based on subscription and limit value. Goto Subscription -> Usage + Quota and filter out to see the new quota limit values.
That’s all.
