Hepsia Advanced Features
The Advanced tab grants you quick access to a set of advanced tools, among them the Memcached distributed memory caching system and the Varnish Cache web accelerator, which will help you optimize your websites and apps without having to leave the Control Panel. Depending on the web hosting package, these features are either added by default or are offered in the form of easy-to-get upgrades. InnoDB and NodeJS support is offered too.
Varnish
Varnish Cache is a web accelerator also referred to as a caching HTTP reverse proxy. You can install it in front of any server that speaks the HTTP protocol and configure it to cache the content. Varnish Cache is very, very fast and will improve your web site's loading speed. One of the main merits of Varnish Cache is the flexibility of its principal configuration mechanism, VCL, which permits you to choose how incoming requests should be tackled.
Memcached
Memcached is a generic distributed memory caching system for boosting the speed of dynamic database-powered websites. It is used to decrease the number of times an external data source (such as a database or API) is read by caching data and objects in RAM. The Memcached distributed memory object caching system uses a two-tier architecture. The Memcached system is employed by some of the most traffic-heavy websites on the web and is supported by popular web apps like Joomla and WordPress.
Node.js
Node.js is a software platform for building scalable network apps. Written in JavaScript, Node.js uses an event-based, non-blocking I/O model that makes it lightweight and effective, great for high-performance data-intensive Internet apps. Node.js uses Google's V8 JavaScript engine, libUV, and a number of built-in libraries.
InnoDB
InnoDB is the default storage engine for the MySQL open-source database management system. A storage engine is the primary software component that a database management system uses to create, retrieve, modify and delete data from a database. The latest version of InnoDB offers substantial improvements in efficacy, dependability and usability. InnoDB offers the standard ACID database transaction attributes, along with referential integrity support. InnoDB is included by default in most binaries distributed by MySQL AB.
