What does High-Availability refer to in Cloud server hosting ?

High-Availability basically refers to the availability of the resources at all the time. In web hosting industry the High-Availability refers to uptime, power, etc. Basically now a days every business almost is dependent on computer systems or IT infrastructure, it may quickly come to halt if the necessary components are not available to server their needs. If the site is unavailable then the competitors site is just a mouse click away. Any disruption to services is measured, not only in dollars and cents, but perhaps, more importantly in reputation.

In other words in IT world high-availability can be said as the system or component that is continuously operational for a desirably long length of time. Similarly the technology in Cloud server hosting environment makes use of a number of different servers and SAN storage’s in a cluster to ensure that there will always be at least one server available to cope up with the load on the cluster or to replace a crashed server. Basically in cloud servers redundant Enterprise Grade Server Hardware In High-Availability Cluster Arrays. In case of failure of one cloud servers or a storage, all services would automatically migrate from the failed server to other live servers, hence providing the high-availability of the resources.

While speaking about the Cloud computing hosting which has come up as the bliss for many business organizations who are looking for the redundant and reliable computing. Cloud hosting services can be said as the services which is consists of or operates in a way that the servers are clustered together, where you have no limit for the resources. In this service the cluster of servers are connected together to improve the performance and reliability.

Cloud hosting services is basically based on servers which are interconnected and serve as one core equipment while sharing the resources among them which in replicates the data on different servers at the time of downtime to provide the redundancy and high-availability of resources as a measure to get over any failure. This is the easy form of data center set up where virtualization technologies are set to use in request to make the whole hosting concept hassle free.
