High Availability Clustering
We specialise in supplying clusters of identical servers as virtual machines running in different geographic locations on our wider area network. Unlike our competitors, these virtual machines are all run and managed by ourselves and are not shared. They are dedicated to your application. Typically, we can offer this in three locations, Dublin Ireland, Boston USA, and Manchester UK. You can have between 2 and 12 nodes in your cluster, (max 4 per geographic location in the same cluster), with 1 to 4 CPU’s per node and 4 to 16Gb of memory per node. All nodes must have the same specification for load balancing performance.
Having two or more server nodes in different geographic locations allows for total resilience should there be a link or a server node failure. An additional benefit is that a node may be taken out of service for software upgrades without your service being affected. Please note: special consideration is given to MySQL clusters with more than two nodes in a master-master loop cluster during planned outages.
Multiple Homed Nodes
We can, with the assistance of our Internet Service Providers, additionally offer as a cost optional extra multiple routes into every node in case of link or routing failure. We are able to offer advice on DNAT (double network address translation) if you need this service.
We can offer single processor high availability LAMP (Linux Apache MySQL Perl/PHP) web hosting from £49.50+VAT per node per month on our Manchester network, minimum 2 nodes. However, as complexity rises, we can tailor a quotation to meet your technical requirements. All you need to do it so call us, explain your requirements, and we will base a tailored quote to meet your exact needs.
