Hyve use a number of caching technologies to enable our clients to serve more of their customers simultaneously, whilst keeping costs down.
Varnish is an HTTP accelerator designed for content-heavy dynamic web sites. Varnish is focused purely on HTTP/S. Varnish is generally used for high-profile, high traffic websites such as Wikipedia. Hyve host a number of clients where Varnish has been set up, including Idiot Drivers UK and the RSPCA news site, which can take 1000s of concurrent connections.
Memcached is a general-purpose distributed memory caching system. It is generally used to speed up dynamic database-driven websites, by caching data and objects in RAM to reduce the number of times an external data source (such as database or API) must be read.
Nginx is a web server that is more commonly used with Linux Operating Systems, but likewise it does have some Windows capability. It can act as a reverse proxy server as well as a load balancer and an HTTP cache. Hyve specifically use it as a web server and HTTP cache. Because Nginx uses an asynchronous event-driven approach to handling requests, Nginx modular event-driven architecture can provide more predictable performance under high loads.
Hyve are 100% carbon neutral. We use carbon offsetting to balance out the release of carbon dioxide from our offices and infrastructure.
