How is the management of virtualized machines and their interaction implemented in the infrastructure?

Management of virtual machines (VMs) in infrastructure is usually implemented through hypervisors (e.g., KVM, VMware ESXi) and orchestration systems.

Key points:

• Creating and configuring VMs — via hypervisor API or management tools (e.g., libvirt, vSphere).
• Automation — using scripts and Infrastructure as Code (IaC) tools (Terraform, Ansible) for scaling and updates.
• Network interaction — configuring virtual networks, VLANs, NAT so that VMs can communicate with each other and external services.
• Monitoring and resource management — tracking CPU, memory, disk load and reallocating resources as needed.

Example: using Terraform, you can describe the configuration of VMs and networks, then automatically deploy and connect them.
