Data virtualization is an approach to data management that allows an application to retrieve and manipulate data without requiring technical details about the data, such as how it is formatted at source, or where it is physically located, [1] and can provide a single customer view (or single view of any other entity) of the overall data.

Virtualization: Server consolidation, service continuity, dev/test, cloud computing Up to near native [citation needed] Yes VMware ESX Server 3.0 Yes, add-on, up to 4 way Yes Yes Virtualization: Server consolidation, service continuity, dev/test Up to near native [citation needed] Yes VMware ESX Server 2.5.3 Yes, add-on, 2 way Yes Yes ...
Full virtualization employs techniques that pools physical computer resources into one or more instances; each running a virtual environment where any software or operating system capable of execution on the raw hardware can be run in the virtual machine. Two common full virtualization techniques are typically used: (a) binary translation and ...
Within a server virtualization environment, applications are interconnected by what is referred to as a virtual switch, which is very different from high-performing hardware-based network switches offered by the likes of Juniper Networks and Cisco Systems. Virtual switches are software-based switches and rely on the movement of packets up and ...
Network virtualization involves platform virtualization, often combined with resource virtualization. Network virtualization is categorized as either external virtualization , combining many networks or parts of networks into a virtual unit, or internal virtualization , providing network-like functionality to software containers on a single ...
The software tool is designed to monitor and report on server virtualization utilizations. [ 8 ] [ 9 ] It produces utilization graphs, [ 10 ] [ 11 ] reports, or alerts of physical or virtual servers on CPU , [ 12 ] memory, IOPS , and many other depending on specific virtualization platform.
OS-level virtualization is an operating system (OS) virtualization paradigm in which the kernel allows the existence of multiple isolated user space instances, including containers (LXC, Solaris Containers, AIX WPARs, HP-UX SRP Containers, Docker, Podman), zones (Solaris Containers), virtual private servers (), partitions, virtual environments (VEs), virtual kernels (DragonFly BSD), and jails ...
In software engineering, containerization is operating-system–level virtualization or application-level virtualization over multiple network resources so that software applications can run in isolated user spaces called containers in any cloud or non-cloud environment, regardless of type or vendor.
