Explain Serverless hosting
Despite the name, serverless hosting does still have a server. But it is not something that has to be managed by the developer. The developer can use as much as needed, and can upgrade when more storage or CPU power is needed.
Why use Serverless hosting
Serverless hosting is a great option so that the company/their developers do not have to manage the server hardware and software. They can simply build and deploy their websites and focus on the programming aspect. There is no maintenance to worry about.
Serverless Provider 1: AWS Lambda
AWS Lambda is one option for serverless hosting. It can be used for a variety of programming purposes, but web applications is one of those. It manages calls for APIs to run code and return data. It allows you 1 million requests for free per month in their free tier, which would be a low cost asset for a smaller company.
Serverless Provider 2: Google Cloud Functions
Google Cloud Functions is a serverless host that also offers pay as you go to run applications on the web. They offer 2 million requests for free each month, plus $300 in free credits for requests over that amount as well. This also has the benefit of integrating well with other Google services.
