A virtual private server (VPS) is a virtual machine sold as a service by an Internet hosting service.

A web hosting service is a type of Internet hosting service that allows individuals and organizations to make their website accessible via the World Wide Web.

Web hosts are companies that provide space on a server owned or leased for use by clients, as well as providing Internet connectivity, typically in a data center.

Web hosts can also provide data center space and connectivity to the Internet for other servers located in their data center, called colocation, also known as Housing in Latin America or France.

A dedicated hosting service, dedicated server, or managed hosting service is a type of Internet hosting in which the client leases an entire server not shared with anyone else.

This is more flexible than shared hosting, as organizations have full control over the server(s), including choice of operating system, hardware, etc.

There is also another level of dedicated or managed hosting commonly referred to as complex managed hosting.

Complex Managed Hosting applies to both physical dedicated servers, Hybrid server and virtual servers, with many companies choosing a hybrid (combination of physical and virtual) hosting solution.

There are many similarities between standard and complex managed hosting but the key difference is the level of administrative and engineering support that the customer pays for – owing to both the increased size and complexity of the infrastructure deployment.

The provider steps in to take over most of the management, including security, memory, storage and IT support.

The service is primarily proactive in nature.

Server administration can usually be provided by the hosting company as an add-on service.

In some cases a dedicated server can offer less overhead and a larger return on investment.

Dedicated servers are most often housed in data centers, similar to colocation facilities, providing redundant power sources and HVAC systems.

Shared web hosting service refers to a web hosting service where many websites reside on one web server connected to the Internet.

This is generally the most economical option for hosting, as the overall cost of server maintenance is amortized over many customers.

In cryptography, a public key certificate, also known as a digital certificate or identity certificate, is an electronic document used to prove the ownership of a public key.

The certificate includes information about the key, information about the identity of its owner (called the subject), and the digital signature of an entity that has verified the certificate's contents (called the issuer).

If the signature is valid, and the software examining the certificate trusts the issuer, then it can use that key to communicate securely with the certificate's subject.

In email encryption, code signing, and e-signature systems, a certificate's subject is typically a person or organization.

However, in Transport Layer Security (TLS) a certificate's subject is typically a computer or other device, though TLS certificates may identify organizations or individuals in addition to their core role in identifying devices.

TLS, sometimes called by its older name Secure Sockets Layer (SSL), is notable for being a part of HTTPS, a protocol for securely browsing the web.
