Most websites don’t outgrow shared hosting until the moment they actually need to, and by then it’s usually obvious: pages start lagging, traffic spikes turn into outages, and nobody can figure out why. That’s the exact moment OnliveServer built its new lineup of India VPS hosting plans for, targeting startups, developers, and ecommerce sites that have hit the ceiling on shared plans. The mechanics are worth understanding if you haven’t shopped for a VPS before. A VPS carves one physical server into several isolated virtual machines, and each one runs its own operating system with resources that belong to it alone. On shared hosting, your site competes with dozens of others for the same pool of CPU and memory, which is exactly why performance gets unpredictable the moment traffic picks up.
