How does Cloud Hosting work?

Website needs can fluctuate drastically on a daily, weekly or
seasonal basis. Cloud hosting allows companies to scale
their computing power to match demand by hosting
the website on multiple servers.

Typically, a hardware and/or service upgrade is
necessary when a website reaches a shared or
dedicated server's capacity, or when the server
crashes due to some sort of failure. Unfortunately,
it takes a lot of time and money to implement
these upgrades and the website will most likely
experience downtime.

The result:
  1. Bulky equipment does not need to be installed
    to enhance performance, power and reliability.
    Resources are pooled from the multiple servers
    to handle any load or demand spikes. When the
    additional resources are no longer needed, it is
    then relieve back to the cloud.
  2. Hosting on multiple servers provide significant
    redundancy against downtime. In case of failure
    of a server in the cloud, failover hardware kick-in
    as a backup to render the required resources.
