So, What is VMware? VMware is a Palo Alto, California based virtualisation and cloud computing company, a subsidiary of Dell Technologies, originally acquired by EMC in 2004, and EMC was later acquired by Dell Technologies in 2016.
VMware is best known for its virtualisation and cloud solutions where virtual machines (VMs) are created and run on a hypervisor (an abstraction layer) known as ESXi that allows multiple guest instance or operating systems (OS) to run on a single hypervisor (ESXi host) simultaneously, and each instance can run single or multiple applications at the same time.
The hypervisor is a software layer that sits between hardware and OS that interacts with hardware and resources and provides an interface to share the available resources to share the available resources to VMs. Enterprise IT rapidly changed over the last few decades as virtualisation became the revolutionary component for IT customers and businesses for creating agile systems.
It reduces the pieces of hardware as many applications and services can be run on fewer hosts by creating multiple VMs on a single server instead of installing several servers, each for a single application or service.
You are either a small business or an enterprise, you may have some servers installed for processing queries, storing files, database services, mail services, etc. The installation and configuration of these physical servers is a hassle and quite expensive.
This is a place where VMware can help while managing and executing multiple apps and services on a single host using its hypervisor.
