What is Serverless Computing?

Serverless computing is a cloud computing execution model where the cloud provider dynamically manages the allocation and provisioning of servers. In this model, developers can build and deploy applications without needing to manage the underlying infrastructure.

Key Features

  • Event-Driven Architecture: Serverless applications respond to events, such as user actions or system events, triggering the execution of code.
  • Automatic Scaling: Serverless platforms scale automatically based on demand, ensuring optimal performance without manual intervention.
  • Cost Efficiency: Users only pay for the compute time consumed, which can significantly reduce costs compared to traditional models where resources are provisioned continuously.
  • Focus on Development: Developers can focus more on writing code and developing features rather than managing servers or infrastructure.

Popular Serverless Providers

Many cloud providers offer serverless computing services, including:

  • AWS Lambda
  • Azure Functions
  • Google Cloud Functions
  • IBM Cloud Functions

Use Cases

Serverless computing is ideal for real-time file processing, API backends, data transformation, and microservices architectures, providing flexibility and efficiency in application development.
