Hepsia Advanced Features
The Advanced tab grants you fast access to an array of advanced features, among them the Memcached distributed memory object caching system and the Varnish Cache web accelerator, which will help you optimize your web sites and applications without the need to leave the hosting Control Panel. Based on the website hosting plan, these features are either added by default or are offered in the form of easily gettable upgrades. InnoDB and NodeJS support is offered too.
Varnish
Varnish Cache is a web accelerator also popular as a caching HTTP reverse proxy. You can install it in front of any server that speaks HTTP and configure it to cache the contents. Varnish Cache is really, really fast and will improve the speed of your web site. One of the important strengths of Varnish Cache is the flexibility of its domain-specific language, VCL, which permits you to define how incoming requests should be handled.
Memcached
Memcached is a generic memory object caching system for increasing the speed of dynamic database-powered websites. It is used to reduce the number of times an external data source (such as a DB or API) is read by caching data and objects in RAM. The Memcached distributed memory caching system uses a client'server architecture. The Memcached memory caching system is employed by some of the most traffic-hungry websites on the World Wide Web and is supported by famous web applications like Joomla and WordPress.
Node.js
Node.js is a software system for building scalable network apps. Written in JavaScript, Node.js uses an event-driven, non-blocking I/O model that makes it lightweight and efficient, ideal for real-time data-intensive network applications. Node.js uses Google's V8 JavaScript engine, libUV, and several in-built libraries.
InnoDB
InnoDB is the default storage engine for the MySQL open-source database management system. A database engine is the underlying software component that a database management system uses to create, retrieve, update and delete data from a database. The latest edition of InnoDB offers serious improvements in efficiency, dependability and functionality. InnoDB offers the standard ACID database transaction features, as well as declarative referential integrity support. It is included by default in most binary distributions from MySQL AB.
