Serverless is a cloud-native development model for building and running applications and services without the need for dedicated servers. Instead of running on a physical or virtual server, a serverless application is typically built using functions, which are executed in response to specific events. This allows the application to be scalable and cost-effective, since the functions only run when needed, and the provider takes care of the underlying infrastructure.
What are the benefits of going serverless?
- Cost savings: Since functions only run when needed, you only pay for the computational resources that are actually used. This can result in significant cost savings compared to running a traditional server-based application.
- Scalability: Serverless applications can automatically scale up or down based on the demand, which makes it easy to handle sudden increases in traffic without having to manually provision additional resources.
- Simplicity: With serverless, you don't have to worry about managing and maintaining the underlying infrastructure, which can save a lot of time and effort. Instead, you can focus on building and deploying your application, and let the provider handle the rest.
- Flexibility: Since serverless applications are built using functions, you have a lot of flexibility in terms of the languages and frameworks that you can use, as well as the types of events that can trigger your functions. This makes it easy to build and deploy applications that are tailored to your specific needs.
