Data backup and disaster recovery vendors expect customers to exit the VMware virtualization platform in the coming years over the virtualization titan’s switch to a subscription model. However, a mass exodus from the platform is unlikely due to the entrenchment that companies have in VMware and the complicated nature of a migration, according to industry sources. The VMware alternatives are expanding. Vendors such as HPE, Veeam and Rubrik have expanded support for open source hypervisors, including Proxmox Virtual Environment (VE), Red Hat OpenShift Virtualization, and Linux Kernel-level Virtual Machines (KVM).
