Virtual server

A virtual server, or virtual machine, is a server created in software on shared physical hardware. It has its own operating system, memory, and disks, but shares the hardware with other virtual machines. Virtual servers are quick to create, move, and resize.

Why it mattersNo need to buy a separate machine: capacity is carved out of hardware you already have.

Also called: Virtual machine, VM, VPS

Benefits

Why it is convenient

  • Created in minutes on existing hardware
  • Capacity can grow without replacing hardware
  • Easy to copy or move to another machine

Watch out

What matters for a contact center

Telephony is sensitive to delays: if neighboring virtual machines overload the shared hardware, audio can break up. That is why the telephony server gets guaranteed CPU cores and memory.

Comparison

Physical or virtual

Physical serverA whole dedicated machine for your system.
Virtual serverA slice of a shared machine's capacity, but faster to create and easier to move.

In CONTACT.WORK

How it works in CONTACT.WORK

You can install the platform on physical or virtual machines running Rocky Linux or another OS of your choice. For ten agents, one machine with four CPU cores, 16 GB of memory, and a 240 GB SSD is enough. For a larger team, the calculator works out how many machines you need.
