How do cloud-based servers work?

As explained above, each server in the cloud helps in carrying out a particular set of tasks, and in the case of failure of any of the servers in the cloud, another server (or servers) temporarily kick-in as a back-up to render the required resources.

Something similar happens in the case of an overload condition too. However, usage of low-quality server hardware can significantly hamper the performance, and such implementations aren’t worthy of being tagged with the VCCLCLOUD — this is typically the case with cheap hosting providers.

Cloud Hosting vs Dedicated Servers & VPS

When you compare dedicated servers to cloud hosting, the reliability factor is a quite solid case in the latter case, since you’ve got multiple servers at your disposal as opposed to a single dedicated server that allows you to cope-up with any emergencies without breaking a sweat.
However, the pricing varies depending upon your actual usage — in the case of heavy usage; the cost factor associated with cloud architecture may be slightly higher, though, so is its resilience.

When you come to VPS and traditional shared hosting, the cost factor is extremely low in this case, quite obviously, but again so is the reliability. In the case of VPS, a single server is divided into multiple chunks, and each portion is managed by a particular user, so the capital investment is reasonably low.
