A Cloud server is part of a clustered group of high performance servers connected using high quality telecommunication links to create one pooled server resource.
The servers may be located in different geographical locations. Cloud hosting is renowned for its High Availability (HA).
The High Availability of Cloud hosting is particularly relevant for when you need to keep business critical systems, such as an ecommerce website or emergency services system, up and running.
HA is designed into the server cluster to prevent a single point of stress or failure at either a hardware, software or communication level from disrupting your business.
Cloud servers have the intelligence to detect points of failure within the server architecture, and initiate a ‘fail-over’ to another member of the cluster thereby keeping your system up and running.
