Microsoft Azure AI services offer a range of powerful tools for developing and deploying artificial intelligence applications. However, with great power comes great responsibility, especially when it comes to managing costs.
One of the primary factors that drive cost in Azure AI Services is the type of resource you use. For example, the cost of using Azure Machine Learning (ML), Azure Cognitive Services, and Azure Bot Services may vary depending on the resources you utilize.
Azure Machine Learning (ML) Costs
Azure Machine Learning offers several pricing tiers: Free, Basic, and Enterprise. The Free tier provides limited access to model training and deployment capabilities. The Basic tier is pay-as-you-go and charges based on the actual compute and storage used. Enterprise, the most expensive tier, provides more advanced features and usage capabilities.
One method to manage costs in Azure ML is to use low-priority compute instances for non-critical jobs. These instances are offered at a significantly reduced cost but are subject to preemption, which makes them unreliable for time-sensitive tasks.
Azure Cognitive Services Costs
The costs of Azure Cognitive Services vary greatly depending on the service being used. For instance, Language Understanding (LUIS) is billed on a per-transaction basis, with lower rates for more transactions.
To control costs, you can consider batching transactions or using lower-cost alternative technologies where possible. For example, if you only require simple keyword extraction, you may not need the full capabilities of LUIS and could use a cheaper alternative service or library.
Azure Bot Services Costs
Azure Bot Services charges are based on the number of messages sent and received. It offers a free tier, which allows for up to 10,000 messages per month, and a Standard tier, which is billed per 1,000 messages after an initial allotment.
One of the ways to manage costs in Azure Bot Service is to build efficient bots that minimize message exchanges. Another method is to host the bots locally for testing and development, limiting usage on Azure to actual deployment.
Budget Alerts and Azure Cost Management Tools
To manage costs, Microsoft provides tools like Azure Cost Management and Azure Advisor, which help users optimize their resource utilization and reduce costs.
Azure Cost Management provides cost analysis and allows setting up cost budgets and alerts. With Azure Advisor, you can get personalized recommendations on optimizing your Azure deployments.
#Setting up budget alert
from azure.mgmt.consumption import ConsumptionManagementClient
consumption_client = ConsumptionManagementClient(credentials, subscription_id)
budget = consumption_client.budgets.create_or_update(
scope = "/subscriptions/{subscription_id}/resourceGroups/{resource_group_name}",
budget_name = "myBudget",
parameters = {
"category": "Cost",
"amount": 100,
"time_grain": "CalculatedMonthly",
"time_period": {
"startDate": "2021-01-01T00:00:00Z",
"endDate": "2025-12-31T00:00:00Z"
},
"notifications": {
"Actual_GreaterThan_90_Percent": {
"enabled": True,
"operator": "GreaterThanOrEqualTo",
"threshold": 90,
"contact_emails": ["email@example.com"],
}
}
}
)
The above example creates a budget for a resource group and sets an alert when the cost exceeds 90% of the budget.
In conclusion, although Azure AI services can rapidly accelerate the development and deployment of AI applications, managing costs is a critical factor to consider. Careful selection of resources, efficient design, and the use of Azure’s cost management tools can significantly help in managing costs.
