Quadra: our custom-designed, fully managed clustered cloud web hosting platform
With over 20 years experience in managing our own network and web hosting for thousands of websites, invested passionately into developing and perfecting a unique platform to deliver the fastest website speeds – especially from power-hungry CMS’s like WordPress – and the highest reliability. High availability hosting at its very best…
Our goal was to create the kind of highly redundant hosting platform which large enterprises use for their sites, but without the hefty price tag usually accompanying such a service. And from just £5.25 per month, we think we’ve accomplished just that!
Only our WebMate Pro package enjoys the benefits of this super-fast, super-reliable platform. Sub-200ms first byte load time (TTFB) is the sweet spot for any website, and Quadra empowers you to achieve that with ease.
Why 4×4 Quadra hosting is better?
In order to create a platform that balances speed and security with 100% uptime, each cluster needs a minimum of four of everything (N+3 redundancy), all working perfectly together in elegant symphony…
We start with our network itself, hosted in the heart of the UK and World Internet Exchanges in Telehouse London. This means less hops to everywhere else on the internet and faster, more reliable speed. Two Edge routers with multiple connections to the internet, combined with four networks (two stacked primary networks, 2 internal). These do much of the firewall and DDoS protection… then…
- Load balancers and Caches: N+3 highly available auto-failover, these also automatically cache your sites content to ensure it’s super fast.
- Web Servers: A bank of these are ready to serve web pages as quickly as possible
- Clustered SQL engines: Multi-master SQL servers to ensure speed and uptime for your site’s databases.
- Shared filesystems: Super fast, fault tolerant SSD drives on independent sub-systems that deliver a massive 80,000+ IOPS / 430Mbps+ – with N+3 redundancy.
- ….combined with additional layers of backup and geo-redundant systems.
The result is Zero downtime, 400% performance and no more fiddling with plugins to squeeze as much performance as possible from WordPress, Joomla etc.
Load balancing for HA Reliability
One of the key features of the Quadra architecture is our bank of four Load balancers. Three of these work in unison for automatic failover protection with a 1 second switchover, and a fourth which is standalone and manual switchover in case of major issues or if we need to perform maintenance or upgrades on the load balancers cluster itself.
These load balancers distribute web requests (and ftp requests) to the best web server – usually distributing evenly to maintain load but also intelligently monitoring for high traffic to any particular site and isolating or maximising its visitors to maintain speeds for all websites in the cluster. Not only that, these also perform some security sentry duties – not to mention fast RAM caches to help speed up your site (NGINX based caching on 64GB RAM disks).
Engineered for Speed
We carefully balance speed with reliability in our entire network, but particularly with nodes within each Quadra cluster. Servers are current and high specification, built and designed for their particular role – rather than a typical shared server often doing several jobs at once and not being very resilient.
SQL servers have super-rapid local disks for caching, super-fast memory (lots allocated as cache) and extremely high clock frequency to process all the math as quickly as possible. Web Servers need multiple processing cores so are typically the latest 40-core chips and a huge amount of ram on each server. Data disks are shared (to ensure reliability) which slows them down a bit, so we make up for it by making them the fastest SSDs and 10Gbps pathways as we can.
Often, much of the “load” in a web server environment is in fetching data from databases – particularly on modern sites which heavily depend on databases like WordPress.
Clustered SQLs is the ultimate way to deliver and process that data for the web servers. A “family” of SQL servers work together in Multi Master-Master replication to share the load whilst remaining perfectly in sync – so uptime is greatly improved. Often, most downtime with other ISPs during “scheduled maintenance” which needs to happen sometimes daily – with a clustered SQL, that can be performed without any downtime at all – scheduled or not. What’s more, the SQL’s employ advanced SQL caching to further speed up the workload from your website.
Backups. Then Backups of Backups.
If there’s one thing we’ve learnt over our 20+ years of hosting websites is that you can never have enough backups. Server failure is a fact of life – and happens all the time. The key is having the backups and platform that can cope with those outages without breaking a sweat.
But to ensure that we cover all bases, and are prepared for extreme outages or security issues, we keep backups, a lot of them – and at no extra cost to you! Snap-shotting of virtual server images, duplicating those between NAS storage engines and offsite, having scheduled 90 day backups of all sites (and duplicating those to multiple locations) and 4-hourly backups of SQLs are just some of the ways we ensure we’re prepared for any eventuality. It also allows you to revert to any website state in the last 90 days effortlessly – so you won’t need those backup plugins or offsite backup services that clog up your WordPress even more.
