Epic failover: web hosting and 100% fault tolerance
Our Cluster web hosting platform is 100% fault tolerant. But what does ‘fault tolerant’ actually mean? Essentially it’s our guarantee that every element of our hosting infrastructure is resilient enough to experience issues while still keeping your website online and available. It’s an all-encompassing concept, from our servers and the software they run, to the high-speed routers that connect it all to the internet – and everything in between.
Defining faults and single points of failure
Before we can really define fault tolerance, we need to define what constitutes a fault. A fault can be anything that has an adverse impact on our infrastructure, everything from power loss and hard disk failure to natural disasters. The point is, even with disruptions like these, our platform provides uninterrupted service for your projects and end-users.
Cluster was designed from the ground up to have no single point of failure (SPOF) – in computing, a SPOF is a part of a network that, in the event of failure, has the potential to take out the whole system. Eliminating SPOFs in a web hosting infrastructure means ensuring redundancy at every level. Or in other words, having multiple paths for your data, so if one fails for any reason, another one can take over instantly.
Anticipating faults: when, not if
Obviously, the physical server that hosts your project is a point where a fault could knock you offline. It’s an inescapable reality that all hardware fails at some point. Even with top-quality components, the very best care and an optimal environment, the occasional failure is an inevitable fact in a data centre full of servers running 24/7. Even ignoring hardware problems, no individual server can offer 100% uptime, with software updates, security patches and essential maintenance regularly taking them offline for brief periods.
But the real question isn’t how to avoid faults, it’s how to plan ahead and build the system so that a single failure or period of downtime is isolated, and in the end irrelevant. With our Cluster platform, every element of the infrastructure is considered ‘failable’ to an extent. For example, your website is hosted on multiple servers, so if one of them fails, well… it doesn’t really matter. Automatic server failover ensures unbroken service, while your files are also backed up across various storage devices, all of which are accessible by other servers in the cluster.
Ultimately, 100% fault tolerance hardens our infrastructure by ensuring that parts of it can fall over without the rest tumbling like dominoes. For your websites and online projects, this means exceptionally high levels of availability and reliability, and the peace of mind that comes along with that.
