Web hosting is an online service that makes your website’s content accessible on the internet. When you purchase a hosting plan, you are renting space on a physical server to store all the website’s files and data.
A virtual private server(VPS) is a machine that hosts all the software and data required to run an application or website. It is called virtual because it only consumes a portion of the server’s underlying physical resources which are managed by a third-party provider. However, you get access to your dedicated resources on that hardware.
A dedicated server is a physical server that’s assigned to a single organization. You need a server to host or run your applications and websites so that your users can access your services. The hosting provider manages and maintains the physical server resources and allocates them to different customers. Depending on the type of hosting solution you choose, you may have to share the underlying physical server resources with other organizations.
Colocation (sometimes known as “colo”) is the practice of renting space for your servers and other computing hardware at a third-party provider’s data center facility. Typically, colocation services include the building in which everything is housed, as well as networking, physical security, redundant power and redundant cooling components, which then support the servers and storage provided by the customer.
