Explain Serverless Hosting
Serverless hosting is a cloud-based development model where developers can build applications without arranging or managing servers. "Serverless" does not mean there are not any servers, but it means that a third party, the cloud provider, is taking care of those and developers don't have to worry about anything.
Why Use Serverless Hosting
When using serverless hosting, the cloud provider looks after the infrastructure which allows developers to focus completely on development. As a result, this lowers time and costs. Serverless hosting can also increase it's capacity on demand. As traffic increases, additional resources are added to assist with managing the load.
