Container is a term that describes an isolated IT hosting environment which runs its own Operating System (OS) alone, which might or might not be a different type of OS than the one of the underlying physical server (infrastructure). Unlike the other Virtual Servers (Virtual Machines), the so-called Containers are created through a virtualization technique called OS Virtualization. It is a software assisted virtualization, which allows any computer hardware to run multiple instances with separate OS concurrently.

The instances (VEs), also containers, work like a separate, real computers. Any software application running on a standard  Operating System can use all resources – CPU power, memory and other computing resources as well as files and folders – of a Container based computer.

Containers crated thought an OS Operating virtualization does not feature the same level of flexibility as the Virtual Machines created with full virtualization, for example. A Container cannot use an OS different from the one that runs on the underlying physical server, or a different guest kernel. If the underlying host runs any Linux distribution, the Containers that run on top of it cannot run Windows.

Managed Shared Web Hosting is a term that refers to Shared Hosting (Shared Web Hosting) service, which is technically administered by the web hosting provider.

Most web hosting providers that offer personal or small business Shared Hosting (Virtual Hosting) services do self-service web hosting. Although there is no term as “Self-service” in the web hosting industry the pharase can be used to explain a web hosting service, which is managed by the account owner.

A Managed Shared Web Hosting service requires the web hosting provider to support the customer’s account client-side, to fix install apps and service, to monitor the resource usage, to do backups, to resolve issues inside the Shared hosting account and to troubleshoot it when necessary.
