Short answer: Shared hosting puts many websites on one server with no root access and no guaranteed resources; a VPS gives you an isolated virtual server with dedicated RAM, root access and your own IP. Switch to a VPS when a site outgrows shared limits, needs custom software or must not be slowed by neighbours.
VPS vs shared hosting explained
On shared hosting the provider runs one web server for hundreds of customers and gives each an account in a control panel. It is cheap and requires no administration, but CPU, memory and I/O are shared, you cannot install system software, and one busy or compromised neighbour can affect everyone.
A VPS isolates your server in its own virtual machine with guaranteed memory and disk, a dedicated IP and root access. You can run any stack (Node.js, Python, Docker, game servers, Windows applications) and tune it, but you are also responsible for updates and security unless you pay for a managed plan.
Signs it is time to move: resource-limit warnings or 508 errors, slow admin pages, the need for software shared hosting does not allow (Redis, Node, background workers), several sites that need isolation, or email and IP reputation problems caused by neighbours.

Frequently asked questions
Is a VPS faster than shared hosting?
Usually, because memory and disk are reserved for you; a small VPS can still be slower than good shared hosting if it is under-sized or badly configured.
Is a VPS harder to manage?
An unmanaged VPS needs basic Linux administration. Managed VPS plans and control panels such as cPanel, Plesk or CloudPanel close most of that gap.
