Serverless hosting is a web-hosting model that places the management of the server onto the service provider, rather than the business. This reduces the amount of time and management needed from a company if they decided to set up their own server, where they must configure everything they need, and ensure proper software is installed to run everything smoothly. Serverless does not mean there are no servers, as servers need to exist for websites to be accessed, but the management and setup of these servers are done by third parties. In addition, the serverless hosting model doesn't require an FTP application to transmit data to and from the server when making edits, but rather uses HTTP requests instead.
There are many reasons as to why people are turning to serverless hosting, some of which include handling unexpectedly high amounts of site traffic, reduced server maintenance, increased deployment and development speeds, and lower costs.
Overall, serverless hosting is a type of web hosting that places the work of server setup and management onto a third party, rather than each company on a case-by-case basis. Not to mention, serverless hosting can provide a wealth of benefits for businesses who may not be experienced in managing a server, trying to save on development costs, and want to make frequent updates to their site.
