VPS vs Cloud Server: Architecture & High-Availability Comparison

Understand the key differences between standalone KVM VPS instances and distributed multi-node cloud clusters with Ceph storage.

Executive Architecture Summary

A VPS runs on a single physical host server, providing maximum compute per rupee. A Cloud Server runs on a distributed hyper-converged cluster with Ceph storage, offering automated hardware failover and dynamic elastic scaling.
