What I know about Serverless Computing?
Serverless computing allows developers to run backend logic without managing servers. Code is executed in response to events (such as HTTP requests), scales automatically, and only runs when needed.
Common serverless platforms include AWS Lambda, Azure Functions, and Google Cloud Functions.
Typical Serverless Architechture
- Client sends HTTP request
- API Gateway receives the request
- Serverless function executes business logic
- Optional database or external API interaction
- JSON response returned to the client
Example Serverless Function (JavaScript)
export const handler = async (event) => {
return {
statusCode: 200,
body: JSON.stringify({
message: "Hello from a serverless function!",
timestamp: new Date().toISOString()
})
};
};
Frontend Integration Concept
In a real application, the frontend would call this function through a RESTful API endpoint. The response would then be used to update the UI dynamically.
fetch('/api/hello')
.then(response => response.json())
.then(data => console.log(data.message));
Why Serverless?
- No server maintenance
- Automatic scaling
- Cost-effective (pay per execution)
- Secure separation of frontend and backend logic
