Serverless Web Applications
Build scalable, cost-effective web applications without the hassle of managing servers.
Zero Infrastructure
No servers to manage, patch, or maintain. Focus on your code, not infrastructure.
Pay-Per-Use
Only pay for what you use. No idle resources or over-provisioning costs.
Auto-Scaling
Automatically scales from zero to millions of users without configuration.
Cost Comparison
Monthly Cost Comparison
Comparison of monthly costs between serverless and traditional server-based architectures across different scales.
Serverless Advantages
- No upfront infrastructure costs
- Pay only for actual usage, not idle capacity
- Automatic scaling without capacity planning
- No server maintenance or patching required

Serverless Web App Architecture
Serverless Web App Architecture
A reference architecture for serverless web applications showing the flow from client through API Gateway, Lambda, and DynamoDB.
Key Components
- S3 & CloudFront - Static content hosting and global CDN
- API Gateway - Managed API endpoints with authentication
- Lambda - Serverless compute for backend logic
- DynamoDB - Managed NoSQL database with millisecond performance
Implementation Example
// Lambda function for API endpoint
exports.handler = async (event) => {
const { id } = event.pathParameters;
// Get item from DynamoDB
const params = {
TableName: process.env.TABLE_NAME,
Key: { id }
};
try {
const result = await dynamoDB.get(params).promise();
return {
statusCode: 200,
body: JSON.stringify(result.Item)
};
} catch (error) {
return {
statusCode: 500,
body: JSON.stringify({ error: error.message })
};
}
