a long list of fixes to address “vulnerabilities” within vSphere. Microsoft offers “Cluster Aware Updating,” a free feature of Windows Server 2020 that enables automated patch management with no scheduled downtime. vSphere patches are virtually ‘nonexistent,’ allowing users to eliminate scheduled downtime. Microsoft offers a prehensive set of DR and high availability features included in Windows Server 2020 R2, such as HyperV Replica and enhancements to failover clustering. Microsoft Azure Site Recovery Manager and StorSimple are game changing solutions that give customers reliable, easytoconfigure services to help back up their data and data centers in the cloud. Microsoft does not have a prehensive disaster recovery (DR) and high availability (HA) solution like VMware’s. VMware is paring its hypervisor product to an operating system, choosing to ignore the fact that HyperV (the hypervisor portion of Windows Server 2020) can be run on bare metal as a separate ponent, just like VMware’s hypervisor. VMware’s hypervisor is only 144 megabytes in size, while Windows Server 2020 is 5 gigabytes in size. With Windows Server 2020, customers get a tremendous value that includes powerful, leadingedge virtualization capabilities built into a platform that goes beyond hypervisors (storage, working, and identity, etc.). VMware has a ‘purposebuilt hypervisor,’ while Microsoft’s solution depends on a general purpose OS.
