What is Serverless Computing?
Serverless computing is a cloud computing execution model that allows developers to build and run applications without managing the underlying infrastructure. Instead of provisioning and managing servers, developers can focus solely on writing code and deploying their applications, while the cloud provider automatically handles the scaling, availability, and server management.
Key Features
- Auto-scaling: Serverless platforms automatically scale your application based on demand, ensuring efficient resource use.
- Cost Efficiency: Users pay only for the compute time used, rather than maintaining servers that might remain idle.
- Event-driven Architecture: Serverless functions can be triggered by various events, such as HTTP requests, database changes, or file uploads.
- Built-in Availability: Cloud providers ensure high availability and fault tolerance, allowing developers to focus on application logic rather than infrastructure.
Use Cases
Common applications of serverless computing include APIs, data processing, web applications, and real-time file processing. It is particularly well-suited for microservices and applications that experience varying loads.
Overall, serverless computing empowers developers to innovate faster by eliminating the complexity of infrastructure management, leading to increased productivity and quicker time-to-market for applications.
