Oracle Virtualization Server is considered a solid virtualization platform, particularly beneficial for users heavily invested in the Oracle ecosystem, but generally, VMware is considered the market leader with wider feature sets and broader community support, while Citrix XenServer offers a good balance between features and affordability, especially for smaller deployments read less

In Citrix XenApp and XenDesktop, the main difference between Citrix Machine Creation Services (MCS) and Citrix Provisioning Services (PVS) is how they provision virtual machines (VMs): MCS Uses a master image to create and manage VMs. MCS is compatible with hypervisors like Citrix XenServer, Microsoft Hyper-V, and VMware ESXi. MCS can create three types of VMs: pooled-random, pooled-static, and dedicated. MCS is used in machine catalogs in cloud environments. PVS Streams the master image to the user device. PVS is a hypervisor agnostic solution that doesn't require a hypervisor to provision VMs. PVS can be used to host physical machines. PVS is not available for cloud deployments. Here are some other differences between MCS and PVS: Resources: MCS uses storage, while PVS streams the image across the network. Performance: The performance, stability, and flexibility of MCS depends on the underlying hypervisor and storage. Image management: PVS' streaming technology makes it easier to manage more virtual desktops from a single master image. read less
