VPS: Virtual Private Servers employ a technology known as virtualization: a technique whereby a physical server is divided into virtual divisions often called containers or virtual machines (VM’s), which make it appear as if your site is running on a dedicated server.
VMware ESXi is an enterprise-class, type-1 hypervisor developed by VMware for deploying and serving virtual computers. As a type-1 hypervisor, ESXi is not a software application that is installed on an operating system (OS) like most of the vps providers do; instead, it includes and integrates vital OS components, such as a kernel. VMware is the world’s leading virtualisation platform and generally considered the most mature virtualization product on the market today. Also, the most expensive to maintain this enterprise level platform.
“VMware, Inc.” is a subsidiary of Dell Technologies that provides cloud computing and platform virtualization software and services. It was the first commercially successful company to virtualize the x86 architecture.
VMware vSphere: The Efficient and Secure Platform for Cloud, vSphere provides a powerful, flexible, and secure foundation for business agility that accelerates the digital transformation to hybrid cloud and success in the digital economy. It helps you run, manage, connect and secure your applications in a common operating environment across the hybrid cloud. With vSphere, you can support new workloads and use cases while keeping pace with the growing needs and complexity of your infrastructure.
When VMware is used on one Dedicated Server known as ESXi host one can get all benefits of virtualization technologies except for the Cloud part where there would be many multiple ESXi hosts running in a group forming a Cloud platform.
When one ESXi host is used, this allows to set maximum and minimum values for resources, so that you only use the resources your applications need. This is real hardware virtualization, meaning better performance from lower requirements on the hypervisor. 100% of the RAM and disk resources are dedicated to each individual VPS server. VMware provides a more isolated environment and gives the vps its own kernel and ESXi is the closest you can get to a true dedicated server in a VPS environment.
The risk of overselling: Overselling is where a host will overcommit resources to certain accounts hoping that not every account uses up all those resources. While everything can be oversold, beware of shady hosting companies overcommitting their servers and putting you on a system with too many containers. VMware vps servers cannot be oversold and one can be confident of getting what is paid for. There are very few Providers in the World who would offer hosting services on VMware virtualization and pricing is very expensive. Check this provider who could be only provider in India to offer such a service on vps servers on VMware ESXi platform and their pricing is also not high.
Most virtualization technologies will never be able to match the virtualization technology and availability numbers provided by VMware. It’s truly enterprise grade virtualization platform and is therefore trusted by most Fortune 500 companies, and for good reason: it’s reliable, fault resilient, and has a security-minded focus.
