Cloud hosting is a type of hosting where several servers work together as though they were one server.
There are many advantages to cloud web hosting and these include:
Flexibility: you can call on more computing power as and when you need to
Less vulnerable to hardware problems: your site is not dependent on a single server
Increased uptime: if anything goes wrong, one of the other multiple servers kick in
Costs: you pay for the resources you use
Back-ups: your site data is stored on multiple servers
Mutiple data centers: you have redundancy compared to a single server
Fast site speeds and better performance
Many cloud hosts have a user-friendly interface to help you configure your account according to your needs
Varied and scalable storage options
Cloud computing utilizes remote networks of connected computers or web servers. When you use a cloud service, the processing and power come from this remote network of computers, not your own local machine.
Virtualization is fundamental to cloud computing. It makes it possible to run multiple operating systems on the same server, which means one physical server can be used for many different purposes. Virtualization software ensures that there is no cross-contamination from one virtual server to another.
Clustering uses multiple computers to provide resilience for an application or network. For example, you can have identical clones of your operating system and database on different machines. If a problem occurs with one, another server will pick up the slack without the end user realizing anything is wrong. This makes for a smooth user experience and reduces downtime.
