Project Overview<\/h3>

The OpenNebula Virtualization Project aimed to implement a scalable and reliable virtualization infrastructure using OpenNebula, an open-source cloud management platform. The architecture design involved a single frontend server managing multiple host servers to host virtual machines (VMs). Storage was handled using a file-based storage backend, and database services were distributed across three separate servers for redundancy, managed by alived.<\/p>
