Azure Serverless

Azure Serverless:

• Azure Serverless refers to a cloud computing model offered by Microsoft Azure, where you can build and deploy applications without managing the underlying infrastructure.
• In a serverless environment, you focus solely on your code, and Azure automatically handles the provisioning, scaling, and management of servers and resources.

Key Aspects

1. Event-Driven
2. No Server Management
3. Automatic Scaling
4. Pay-as-you-go Pricing
5. Stateless
6. Focus on Business Logic
