Virtualisation: The Technology Behind Cloud
Server virtualisation is the technology that makes cloud hosting economically viable and technically reliable. Without it, every business would need its own dedicated physical server — far too expensive for most Indian SMEs. Virtualisation allows one powerful physical server to host multiple independent virtual servers simultaneously, with complete isolation between them.
Understanding the basics of virtualisation helps you ask the right questions about your hosting provider and understand why certain specifications (dedicated vs shared resources) matter for your business.
The Hypervisor: Software That Creates Virtual Machines
A hypervisor is software that runs directly on the physical server hardware and manages the creation and operation of virtual machines. The hypervisor intercepts all hardware requests from virtual machines and maps them to actual physical hardware resources. Major enterprise hypervisors: VMware ESXi, Microsoft Hyper-V, and KVM (Kernel-based Virtual Machine).
The hypervisor maintains the isolation boundary between virtual machines — VM 1 cannot access VM 2's memory, cannot read VM 2's storage, and cannot consume more than its allocated CPU cycles. This isolation is enforced at the hardware level through CPU virtualisation extensions (Intel VT-x, AMD-V) — not just software rules.
Your VPS: A Virtual Machine With Dedicated Resources
Your VPS (Virtual Private Server) is a virtual machine running on a physical server in M A Global Network's data centre. It has:
- Dedicated vCPU cores: Real CPU core time allocated exclusively to your VM — not drawn from a shared pool
- Dedicated RAM: Memory reserved for your VM — other VMs cannot use it regardless of their activity
- Dedicated NVMe storage: Storage allocated from the NVMe SSD array for your VM's exclusive use
- Independent OS: Windows Server 2022 running in your VM — other VMs cannot affect your OS or its configuration
From inside your VM, it looks and feels exactly like a physical server. Windows Server 2022 sees its CPU, RAM, and storage. Applications installed in the VM — Tally, Busy, any Windows application — run as if on a physical machine. The virtualisation layer is transparent to everything running inside.
Why "Dedicated" Resources Matter
Some VPS providers offer "burstable" resources — the VM has a guaranteed minimum allocation but can burst to higher resource usage when available. This model means your VM competes with other VMs on the same physical server for excess resources. During periods when all VMs are under high load simultaneously — which tends to happen when Indian businesses are all in their busiest periods — there are no excess resources to burst into. Performance degrades for everyone.
Dedicated resources means your VM's CPU and RAM allocation is reserved exclusively, regardless of other VMs' activity. GST filing week performance is identical to a quiet Sunday morning — because dedicated resources are always there, not contested.
Live Migration: Transparency of Physical Hardware Changes
One technical benefit of virtualisation: when the physical server hardware needs maintenance or replacement, VMs can be live-migrated to other physical servers with minimal or no interruption. The VM is copied to new hardware while running, and the workload switches over at a moment when the two copies are synchronised — typically with less than 1 second of interruption. Hardware maintenance that would require hours of downtime on a bare-metal server happens transparently for virtualised workloads.
Frequently Asked Questions
Virtualisation provides hardware-level isolation between VMs. Your VM cannot read another customer's VM's memory, cannot access their storage, and cannot intercept their network traffic. The hypervisor enforces this isolation using CPU hardware virtualisation extensions. While software vulnerabilities have occasionally been found in hypervisors (VM escape vulnerabilities), these are rare, quickly patched, and primarily affect adversarial environments. For business hosting purposes, virtualisation provides robust isolation between customers.
