Networks

In the next module, we will begin covering type-1 hypervisors. However, before diving into that, it’s essential first to understand the networking aspects involved. When setting up a type-1 hypervisor, you may need to configure several networks to support the infrastructure effectively.

Management Network: The first network to be set up is the Management Network. This network lets you connect to, configure, and maintain the type-1 hypervisor. It should be secured with restricted access, granting entry only to those who require it.
User Network: The next network is the User Network, which allows users to interact with your VMs. Depending on the virtual machines and services involved, this network may have less stringent security, which is why the Management Network is isolated and secured.
Storage Network: The Storage Network provides access to storage solutions like a SAN or NAS. You can configure the hypervisor to store VMs, backups, or ISO files on this network. Like the Management Network, this should also be secure.
Cluster Network: The final network to configure is the Cluster Network. This network connects multiple hypervisors, allowing them to share and migrate resources efficiently. Securing this network is crucial, as it handles critical communications between hypervisors.

Why so many networks?

We need to configure these four networks to enhance security and prevent bottlenecks within our infrastructure. Imagine installing a new VM using an ISO stored on a SAN while customers actively interact with services—all on the same network! This setup could lead to significant issues such as latency, jitter, and dropped packets for your customers. The heavy data transfer between the SAN and the hypervisor would compete for bandwidth, and you’d also be accessing the management interface on a public network, which is a significant security risk. By separating these functions into distinct networks, each with its own purpose, we avoid these problems and ensure smooth, secure operations.

Setting up the necessary networks first will save you time and headaches in the long run.
