Benefits of Serverless

1. Cost-effective: Serverless computing only charges you for the actual usage, which can lead to cost savings compared to pre-allocated, always-on servers.
2. Scalability: Serverless platforms automatically scale based on the number of requests, allowing your application to handle traffic spikes without manual intervention.
3. Reduced operational overhead: With serverless computing, the cloud provider takes care of server management, so you can focus on developing and deploying your application.
4. Faster time to market: Serverless architectures simplify the development and deployment process, allowing you to get your applications up and running more quickly.
5. Pay-as-you-go pricing model: With serverless, you only pay for the compute resources you actually use, rather than pre-allocating resources.
6. Event-driven architecture: Serverless platforms are designed to handle events, making it easy to build applications that respond to user actions, changes in data, or other triggers. 7
