IT - Virtualization

Organizations today often require many servers in different physical locations, each operating at their highest capacity to drive efficiency and ROI

"This has been made possible with the use of virtualization technologies that allow a single physical server to run multiple virtual machines that each have their own guest operating system.

Virtualization technology has its origins in the 1960s, with work that was done at IBM on time-sharing of mainframe computers. VMware didn't arrive on the scene until the late 1990s. In 2001, VMware introduced ESX Server, a Type-1 hypervisor. This technology doesn't require a host operating system to run virtual machines. Instead, the hypervisor runs on the 'bare metal'..."

Preparing For Enterprise-Class Containerisation
ComputerWeekly, March 29th, 2021
As more workloads are deployed in containers, IT teams will need to assess how to manage container sprawl, reduce cloud bills and support databases

"Despite the option to move essentially ephemeral computing resources and data between public, private and hybrid clouds, there is still an all-encompassing push to deploy unmodified monolithic applications in virtual machines (VMs) running on public cloud infrastructure.

However, it is more efficient to break down an application into functional blocks, each of which runs in its own container. The Computer Weekly Developer's Network (CWDN) asked industry experts about the modern trends, dynamics and challenges facing organisations as they migrate to the micro-engineering software world of containerisation..."
