Automation is a key aspectDevOpsand agile development. On January 19Th,we publishedgeneral availability of the Azure Quota REST API. The Quotas API allows you to automate quota management and programmatically integrate it into your applications, tools, and existing systems. Now you can move your applications and systems to the cloud faster and have more time to focus on your core business.
In this blog post, we'll give you an overview of the recently released Quota REST API and a step-by-step tutorial with example code that shows how to use it when you hit your quota limit. In short, for the rest of this blog we will be using the Quota API.
What are quotas?
Odds, also calledservice limitationsare the maximum values for resources, actions, and items in an Azure account.
AAzure subscriptionis an agreement between the customer and Microsoft that enables the customer to obtain Azure services. Subscription prices and related terms are determined by the offer selected for the subscription. There is one for a specific subscription, region and SKUZadana quota. Each Azure service defines its own quotas and default values. Here are some things to keep in mind about prospects:
- Just like credit cards have credit limits, Azure services also have limits. A quota is a consumption limit for an Azure resource.
- The quota is distributed across all services in each subscription. When estimating your capacity needs, you should calculate the usage of all services.
- Some services have adjustable limits. The limit can be increased above the default limit, but not over the maximum limit. Default limits differ depending on the type of offer category, eg Eg. free trial, pay-as-you-go and VM series (eg Dv4, Fsv2 and Easv4). SeeLimits, quotas, and limits for Azure subscriptions and servicesDetails of standard and maximum limits can be found here.
Why Quota API?
To compete effectively, organizations must create an environment in which developers can perform at their best and in which operations teams can confidently meet the reliability, security, and compliance requirements their organizations expect. That requires advanced cloud capabilities designed to support modern constructs like containers, DevOps, APIs, and managed services—and the flexibility to work across environments and teams. The Quotas API can address this need to automate quota management and enable the integration of quota management with your existing tools and applications. For more information on the business benefits of using the Quota API, see ourzapis na bloguim Microsoft Azure blog.
Using the Quota API
The Azure Quotas API is a one-stop shop for automating the process of viewing and managing quotas and eliminating the manual process of creating and managing quotas through support tickets in the Azure portal. Using the Azure Quotas API, you can easily determine your current quota usage and request increases. The current version of the Quota API allows you to manage service limits (quotas) of Azure Virtual Machines (Cores/vCPU) and Azure Machine Learning. In future releases, you can use this feature to query current usage and quotas for additional Azure services and resources.
Automate Azure quota management
usage scenario
This use case demonstrates how to use the Quotas API to automate quota management to improve agility, developer speed, and efficiency in IT operations.
Anna is a lead developer on the Contoso Cloud Readiness team. Contoso is an A/B testing company that tests firmware for cloud hardware approval. During testing, Anna needs to create many virtual machines (VMs) to test the firmware on a large scale. One of the challenges Anna faces is that she cannot provision new virtual machines because the quota limit has been reached. This happens frequently and unexpectedly due to the inorganic growth of VM usage in their organization. To continue her workflow, Anna manually creates a support ticket to request a quota increase. To improve the efficiency of its workflow, it now uses the Azure Quota API to automate quota requests and verification operations from start to finish. It can check usage and monitor when its virtual machines reach their quota limit and automatically send quota requests to increase the limit. Anna's manual quota request process is now fully automated. This has greatly helped their operations by paving the way for continuous firmware testing.
When should a quota increase be requested?
The Quotas API allows you to determine your current quota limit and usage metrics and compare them to your quota needs. To determine when to request a quota increase, follow this workflow:
- Determine how many quotas are left:
remaining quota = quota limit - current usage
- Request a quota increase if the remaining quota is less than the quota you need. If the remaining quota is more than the quota you need, you do not need to request a quota increase.
Quota increase request
Here is an example showing how to determine if a quota increase is needed and how to request it.
Anna plans to launch a new service in the eastern region of the US (change). It requires 20 general-purpose VMs for testing and development that provide a balanced mix of vCPUs, memory, and local disk. She chose 20 D3 v2 VMs (StandardD3V2Familija) that will support most of their production workloads. It also requires 5 NDs series VMs (StandardNDSFobitelj) to support parallel computing and machine learning workloads.
After the initial deployment, Anna follows these steps to review the current usage of her NDs series VMs and determine if she should request a quota increase for the NDs series SKUs in the US East region.
- Anna checks the remaining quota limit usingQuota API GET operation. Anna makes this GET request:
and get this answer:DOWNLOAD https://management.azure.com/subscriptions/00000000-0000/providers/Microsoft.Capacity/resourceProviders/Microsoft.Compute/locations/eastus/serviceLimits/standardNDSFamily?api-version=2020-10-25{ "properties": { "limit": 10, // Kontingentlimit "unit": "Count", "currentValue": 5, // Aktuelle Verwendung "name": { "value": "standardNDSFamily", "localizedValue" : „Standardni NDS obiteljski vCPU-ovi“ } }} - It uses the GET response to determine how many quotas are left for that VM:
remaining quota = quota limit - current usage = 10 - 5 = 5 - It needs a quota of 10 for VM, so it should be requestedQuota increase by 5. So your new quota limit is:
new quota limit = old quota limit + quota increase = 10 + 5 = 15 - Anna uses the Quota API PUT operation to request a quota increase of 5 with this PUT request:
PUT https://management.azure.com/subscriptions/00000000-0000/providers/Microsoft.Capacity/resourceProviders/Microsoft.Compute/locations/eastus/serviceLimits/standardNDSFamily?api-version=2020-10-25and request text:
(Video) Quota by API Product{ "properties": { "limit": 15, // Neues Limit "unit": "Count", "name": { "value": "standardNDSFamily" } } }
If there is a quota error
If you get a quota error after an increase request, try a lower number instead of retrying a higher number. Using a higher number can still lead to errors. If you're still getting quota errors, follow the instructions atHow to create a support ticket from the Azure portalor useAzure-Supportticket-REST-APIto create it programmatically.
