What is Serverless Architecture?
Serverless architecture is a cloud computing execution model that allows developers to build and run applications without having to manage servers. Instead of provisioning servers, developers can focus on writing code, deploying it in the cloud, and the cloud provider handles the infrastructure management.
Key Features
- Event-driven: Functions are triggered by events such as HTTP requests or database changes.
- Scalability: Automatically scales up or down based on demand, ensuring optimal resource usage.
- Pay-as-you-go: Users only pay for the compute time consumed, reducing costs significantly.
- Reduced operational burden: Minimal server maintenance allows developers to concentrate on application logic.
Benefits
Serverless architecture offers numerous advantages, including faster development cycles, easier collaboration among teams, and improved resource efficiency. It also allows organizations to innovate quickly and respond promptly to changing market demands.
Use Cases
Common use cases for serverless architecture include web APIs, data processing, real-time file processing, and IoT backends. Major cloud providers offering serverless solutions include AWS Lambda, Azure Functions, and Google Cloud Functions.
