Serverless is a cloud computing model where developers build and run applications without managing physical or virtual servers. The cloud provider automatically handles infrastructure tasks such as server provisioning, scaling, maintenance, and resource management.
In modern backend and cloud development, serverless architecture allows developers to focus mainly on application logic while the platform dynamically allocates resources based on demand. It is commonly used for APIs, event-driven systems, and microservices.
For example:
- A backend function automatically runs when a user uploads a file.
- An e-commerce platform processes payments through serverless functions.
- A mobile app backend scales automatically during traffic spikes.
- A notification system triggers emails or alerts based on user actions.
Common technologies and concepts related to serverless computing include:
- AWS Lambda
- Google Cloud Functions
- Azure Functions
- Event-driven Architecture
- Auto Scaling
- Function as a Service (FaaS)
- Microservices
- Cloud Computing
- API Gateways
