How does serverless computing impact web development?

Serverless computing is transforming web development by abstracting infrastructure management and allowing developers to focus solely on writing code. Here’s how it impacts web development:

1. No Server Management
   Developers don’t need to provision, scale, or maintain servers. Cloud providers like AWS Lambda, Azure Functions, and Google Cloud Functions handle all backend infrastructure automatically.

2. Cost Efficiency
   Serverless platforms follow a pay-as-you-go model, meaning you only pay for the actual compute time used. This eliminates costs associated with idle servers, making it ideal for startups and low-traffic apps.

3. Faster Time to Market
   With no need to set up servers or backend infrastructure, developers can quickly deploy applications, allowing for rapid prototyping and iteration.

4. Auto-Scaling
   Serverless applications automatically scale based on demand. Whether serving 10 users or 10,000, the platform adjusts resources dynamically, preventing performance issues.

5. Improved Security
   Cloud providers handle patching and security updates, reducing vulnerabilities associated with traditional server management. However, developers still need to ensure secure API endpoints and data handling.

6. Event-Driven Execution
   Serverless functions run in response to events (e.g., user actions, database updates, file uploads). This is perfect for building microservices, APIs, and real-time applications.

7. Challenges of Serverless Computing
   Despite its advantages, serverless has some drawbacks:

Cold starts: Functions may take longer to respond after periods of inactivity.
Vendor lock-in: Serverless apps often depend on a specific cloud provider's ecosystem.
Limited execution time: Some platforms restrict function runtime duration.
Use Cases in Web Development
API Backends – Easily deploy RESTful APIs with AWS Lambda or Firebase Functions.
Real-time Data Processing – Process user events, logs, or IoT data.
Scheduled Tasks – Automate cron jobs, backups, and periodic data updates.
File Processing – Process images, videos, and documents dynamically.
