When it comes to a flexible, scalable and reliable web infrastructure to operate a business, Cloud hosting becomes the most ideal solution nowadays. It is a cost effective solution as well, since the charges are limited to only those resources that users use. Hosting costs are offered in a way that it provides the most control on users hosting budget for example on usage hour, traffic volume, special pricing for sudden traffic spikes etc. Service up-gradation and expansion, as business demands, are easily possible without expenses on costly devices. Content security is ensured by distributing data across redundant servers. The cloud protects hosted information against hardware failure. Automated backups ensure up-to-date content access to the users. It is just a “One Click” solution to multiple web requirements to operate any business.
Cloud hosting is a web hosting service delivered from a group of connected servers. In general, a hosting service can be considered cloud hosting when it is delivered from a fully redundant, multi-server system, in which the resources are dynamically scalable and often virtualized. A cloud hosting service is usually delivered from a load-balanced cluster server platform, while the data is stored in a SAN (Storage Area Network). Cloud hosting providers measure compute cycles, an indicator which measures how much processing time applications require. This enables cloud hosting to be provided and billed as a part of a different service model than that used by other web hosting services.
The key advantages of cloud hosting service include:
Pay only for the resources used
Scalability; customers can easily increase or decrease resources without moving sites to other servers.
Servers can be deployed instantly.
It provides better uptime than other types of web hosting.
Traffic spikes aren't a problem; the cloud can handle them.
If the servers are in different datacenters, datacenter problems can be less of a concern.
Different technologies can be used together that can't be used together without cloud hosting. For example, .PHP and .asp files can work on the same site, even in the same folder, drawing on technologies within the cloud.
Users need not to install hardware or software. Instead, they can connect with a cloud that has the hardware or software they require.
