What it is
vSphere is the foundation of virtualisation at VMware: the ESXi hypervisor on every server, and vCenter, which joins the servers into clusters. When a host in a cluster fails, its virtual machines restart on the others, in the same datacentre or across two sites. Servers, desktops and containers run on it.
vSphere is part of both large Broadcom bundles, vSphere Foundation and VMware Cloud Foundation. On its own it is called vSphere Standard: the hypervisor with one vCenter instance.
Where vSphere Standard stands
The last major version of vSphere Standard is 8, from 2022. vSphere 9 shipped in 2025 with VCF 9; there was no version 9 of vSphere Standard.
In September 2026 Broadcom announced a new version of vSphere Standard, meant for environments of around 128 cores. Its name, scope and price have not been published; Broadcom has said details are likely at VMware Explore in Europe in mid-October.
Which bundle can be bought in which country is set by Broadcom per region. At the end of 2025 Broadcom withdrew vSphere Foundation from parts of EMEA and explicitly kept vSphere Standard there. Broadcom has not published which countries are affected and refers customers to its partners for availability.
Architectures
Which architecture fits depends on what the business needs. Each has advantages and drawbacks, and our engineers work out the right one with you.
- Single site. All ESXi servers in the same datacentre. The classic variant, with the fewest prerequisites; disaster recovery needs additional solutions.
- Stretched cluster. The ESXi servers stand at two sites and belong to the same cluster. More prerequisites, in return for advantages in high availability.
- Remote office. Branches with their own hardware on site, vCenter run centrally. It combines with either of the other two.
How we build it
We do not install ESXi by hand. Our own installation automation, the ESXi Deployment Appliance (EDA), installs one, ten or hundreds of ESXi servers without errors, and we have maintained it for years. It comes with every project that includes vSphere, upgrades too, so nothing old is carried over. How it came about is in Rapid ESXi Deployment Appliance.
What vCenter offers through its interfaces is usable from PowerShell with PowerCLI. Our engineers have automated countless tasks with it in large environments. Some scripts delivered a function that later arrived natively in the product, such as the correct conversion of resource pool shares; others customers have used for years, especially in stretched clusters.
Protecting the platform
A stretched cluster absorbs many failures, but not every one, and no attack. For disaster recovery we use Zerto and Veeam, and our engineers recertify on both with every new version.
