In the evolving landscape of cloud computing, serverless architecture is transforming how developers build and deploy applications. One of the most powerful tools enabling this transformation in Microsoft Azure is Azure Functions. This serverless compute service helps developers run code on-demand without worrying about infrastructure, scaling, or provisioning servers.
5 Important Q&A on Azure Functions
1. How are Azure Functions billed?
They're billed based on the number of executions and execution time, making it a cost-effective solution for unpredictable workloads.
2. Can Azure Functions connect to databases?
Yes, you can use bindings or custom code to connect to services like Azure SQL, Cosmos DB, and more.
3. Are Azure Functions suitable for large applications?
Yes, especially when split into microservices. However, orchestration might be required using Durable Functions or Azure Logic Apps.
4. How do I secure my Azure Functions?
Use authentication settings, managed identities, and API keys. Also, protect sensitive data using Azure Key Vault.
5. What is the difference between Consumption and Premium plans in Azure Functions?
Consumption Plan: Auto-scales and billed per execution.
Premium Plan: Offers better performance, VNET support, and pre-warmed instances.
