Overview of this book

Proxmox is an open source server virtualization solution that has enterprise-class features for managing virtual machines, for storage, and to virtualize both Linux and Windows application workloads. You'll begin with a refresher on the advanced installation features and the Proxmox GUI to familiarize yourself with the Proxmox VE hypervisor. Then, you'll move on to explore Proxmox under the hood, focusing on storage systems, such as Ceph, used with Proxmox. Moving on, you'll learn to manage KVM virtual machines, deploy Linux containers fast, and see how networking is handled in Proxmox. You'll also learn how to protect a cluster or a VM with a firewall and explore the new high availability features introduced in Proxmox VE 5.0. Next, you'll dive deeper into the backup/restore strategy and see how to properly update and upgrade a Proxmox node. Later, you'll learn how to monitor a Proxmox cluster and all of its components using Zabbix. Finally, you'll discover how to recover Promox from disaster strikes through some real-world examples. By the end of the book, you'll be an expert at making Proxmox work in production environments with minimal downtime.

Summary


In this chapter, we learned about one of the most powerful features of Proxmox, the built-in firewall. We learned what it is and how to implement it to protect the entire cluster, Proxmox host nodes, and virtual machines. We learned how to manage the firewall rules and configuration using both the GUI and CLI. Proxmox adds security where it is needed the most. By leveraging a flexible and granular firewall protection at the hypervisor level, we are now able to have a better-secured cluster. This is not to say that firewall policies are not needed internally in each VM, but having a firewall built into the hypervisor offers an extra layer of protection from an infrastructural point of view.

In the next chapter, we are going to learn about the Proxmox VE High Availability feature for VMs, which has been completely redesigned from the ground up. The new changes brought higher stability while making the management and configuration a much simpler task.
