Datacenter vs Standard vs Essentials

• Datacenter — unlimited virtual machines, Storage Spaces Direct & Shielded VMs. Built for highly virtualized data centers and private cloud.
• Standard — the same core features with rights to run up to 2 VMs. Ideal for physical or lightly virtualized servers.
• Essentials — a simple single-server edition for small businesses with up to 25 users / 50 devices, with no CALs required.

Standard suits most small and mid-size deployments, Datacenter is for dense virtualization, and Essentials is the cheapest route for a small office.
