SSL certificates are needed because they encrypt the data exchange between your website and the visitor’s browser, making it impossible for hackers to get access to this data. This is especially important if you store your customers’ credit card information. For a complete website hosting experience, HostPapa provides you with a Let’s Encrypt SSL Certificate completely free of charge!

A VPS runs its own copy of an operating system (OS), and customers may have superuser-level access to that operating system instance, so they can install almost any software that runs on that OS. For many purposes they are functionally equivalent to a dedicated physical server, and being software-defined, are able to be much more easily created and configured. They are priced much lower than an equivalent physical server. However, as they share the underlying physical hardware with other VPSes, performance may be lower, depending on the workload of any other executing virtual machines.[1]
