A high-availability (HA) cluster is an IT architecture in which several physical servers work together as a single system. If one of the servers fails, the others automatically take over its workloads, with no interruption for users. The result: minimal downtime and guaranteed business continuity.<\/p>\n
For companies that depend on critical applications \u2014 ERP, databases, file servers, email \u2014 an HA cluster is no longer a luxury but a necessity.<\/p>\n
Virtualization lets you run multiple virtual servers on a single physical server, making better use of hardware and reducing costs. The three main platforms we deploy at Gobalt Solutions are:<\/p>\n
VMware vSphere \/ vSAN<\/strong> \u2014 the reference enterprise solution, with advanced HA features, vMotion (live migration of virtual machines) and distributed storage through vSAN. Ideal for complex environments with high performance and availability requirements.<\/p>\n Microsoft Hyper-V<\/strong> \u2014 built natively into Windows Server, Hyper-V offers a solid virtualization solution at a lower cost. With Failover Clustering and Storage Spaces Direct (S2D), it can deliver availability comparable to VMware in many scenarios.<\/p>\n Proxmox VE<\/strong> \u2014 an open-source alternative that combines KVM virtualization with LXC containers. Excellent for companies that want flexibility and lower licensing costs without sacrificing essential features.<\/p>\n The choice depends on several factors: budget, environment complexity, performance requirements, team experience and growth plans. VMware remains the preferred choice for complex enterprise environments, Hyper-V fits very well in Microsoft ecosystems, and Proxmox is ideal for companies that prefer lower-cost open-source solutions.<\/p>\n At Gobalt Solutions we have deployed HA clusters on all three platforms across diverse industries \u2014 from aerospace and paper manufacturing to textiles and woodworking. Every project started from a careful analysis of the client's needs, not from a preset technology preference.<\/p>\n Lower hardware costs<\/strong> \u2014 fewer physical servers mean lower costs for power, cooling and data center space.<\/p>\n Fast disaster recovery<\/strong> \u2014 virtual machines can be replicated and restored much faster than traditional physical servers.<\/p>\n Scalability<\/strong> \u2014 additional resources (CPU, memory, storage) can be added without service interruption.<\/p>\n Snapshots and simpler backups<\/strong> \u2014 the ability to create instant restore points before any major change.<\/p>\n If your current infrastructure still relies on standalone physical servers or an outdated virtualization solution, we invite you to explore the available options together.
