Redundancy
“How can built-in redundancy give me a better night’s sleep?”
Hybrid Web Cluster gives you full control over redundancy levels
In order to achieve military-grade fault tolerance, Hybrid Web Cluster allows you to specify exactly how many redundant copies of each website are kept – starting at 2 for basic business redundancy, this means that each website will be stored on two servers at any one time, so if either one of them fails you will not experience any downtime. However, the redundancy level (or ‘redundancy invariant’) is fully configurable and limited only by the number of available cluster nodes – you could elect to have each website continuously backed-up to every single node in the cluster. It’s even possible to specify that each website must be stored at more than one separate data-centre, providing you with military-grade fault tolerance – your website is atom bomb-proof.
Hybrid Web Cluster has no single point of failure. The ‘redundancy invariant’ guarantees that data is sufficiently replicated at all times to cope with the failure of many nodes, and upon failure the nodes act quickly to re-establish the redundancy. In other words, your data is always safe, and failures are dealt with quickly and automatically.
Hybrid Web Cluster can scale linearly according to how many servers you add to the cluster. More servers = more storage capacity, and because the storage for each website is stored locally on the node which it is currently live on (and backed up to some, but not all of the other nodes) it is fast and does not suffer the performance and bandwidth-use penalties of needing to access your storage over the network.
