Recommendations for connecting dynamic virtual machines to Kaspersky Security Center

Dynamic virtual machines (also referred to as dynamic VMs) consume more resources than static virtual machines.

For more information on dynamic virtual machines, see Support of dynamic virtual machines.

When a new dynamic VM is connected, Kaspersky Security Center creates an icon for this dynamic VM in Administration Console and moves the dynamic VM to the administration group. After that, the dynamic VM is added to the Administration Server database. The Administration Server is fully synchronized with Network Agent installed on this dynamic VM.

In an organization's network, Network Agent creates the following network lists for each dynamic VM:

  • Hardware
  • Installed software
  • Detected vulnerabilities
  • Events and lists of executable files of the Application control component

The Network Agent transfers these network lists to the Administration Server. The size of the network lists depends on components installed on the dynamic VM, and may affect the performance of Kaspersky Security Center and database management system (DBMS). Note that the load can grow non-linearly.

After the user finishes working with the dynamic VM and turns it off, this machine is then removed from the virtual infrastructure and entries about this machine are removed from the Administration Server database.

All these actions consume a lot of Kaspersky Security Center and Administration Server database resources, and can reduce the performance of Kaspersky Security Center and DBMS. We recommend that you connect up to 20,000 dynamic VMs to Kaspersky Security Center.

You can connect more than 20,000 dynamic VMs to Kaspersky Security Center if the connected dynamic VMs perform standard operations (for example, database updates) and consume no more than 80 percent of memory and 75–80 percent of available cores.

Changing policy settings, software or operating system on the dynamic VM can reduce or increase resource consumption. The consumption of 80–95 percent of resources is considered optimal.
