Build a high availability cluster with PROXMOX and CEPH

Virtualization is a cornerstone of modern IT infrastructure, and large corporations have increasingly adopted it over the past few years. Instead of managing numerous physical servers for each application, organizations now leverage fewer, more powerful servers to host multiple virtual machines. Technologies like KVM and QEMU, often utilized on VMware ESX Servers, enable this efficient approach. These enterprise-grade solutions come with a corresponding price point.

Proxmox emerges as a compelling alternative, offering virtualization alongside Linux containers and a robust suite of enterprise features. These include software-defined storage, replication, backup, thin storage provisioning, and high availability.

This course guides you through building your first High Availability (HA) and Scalable Cluster. Learn how to create a cluster that can seamlessly accommodate additional storage or compute power without any downtime. The cluster will maintain uptime even if individual servers fail.

You'll gain essential knowledge and practical skills to construct a production-ready, redundant cluster using Proxmox and Ceph, both proven technologies.

Proxmox is a powerful virtualization platform packed with features like live migration, high availability groups, and comprehensive backups. Ceph provides a highly scalable and reliable storage solution designed for optimal performance and data integrity. With Ceph storage, you can dynamically expand your storage capacity without any downtime. This course demystifies Ceph, demonstrating that it's a manageable and intelligent solution.

This introductory course is designed to equip you with the fundamental skills and knowledge needed to build your first High Availability Cluster. If you've explored OpenStack and found it overly complex for your needs, this course is an excellent fit, particularly for smaller deployments.

Note: As of the time of writing, the course focuses on Proxmox version 7.
