Hepsia Advanced Features
The Advanced tab gives you quick access to an array of advanced tools, among them the Memcached distributed memory caching system and the Varnish Cache web application accelerator, which will help you optimize your sites and apps without the need to leave the hosting Control Panel. Depending on the web hosting plan, these tools are either added by default or are offered in the form of easily gettable upgrades. InnoDB and NodeJS support is offered as well.
Varnish
Varnish Cache is a web application 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 content. Varnish Cache is really, really fast and will increase the speed of your website. One of the important pluses of Varnish Cache is the flexibility of its principal configuration mechanism, VCL, which allows you to specify how incoming requests should be handled.
Memcached
Memcached is a general-purpose memory caching system for increasing the loading 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 memory object caching system uses a two-tier architecture. The Memcached distributed memory caching system is employed by some of the most regularly visited web sites on the Internet and is supported by popular web apps like Joomla and WordPress.
Node.js
Node.js is a software platform for building scalable Internet applications. Written in JavaScript, Node.js uses an event-driven, asynchronous input/output model that makes it lightweight and effective, suitable for real-time content-heavy apps. Node.js uses Google's V8 JavaScript engine, libUV, and a number of built-in libraries.
InnoDB
InnoDB is the default database engine for the MySQL open-source database management system. A database engine is the principal software component that a database management system uses to create, read, update and delete data from a database. Its latest release offers serious improvements in performance, reliability and functionality. InnoDB offers the standard ACID-compliant database transaction properties, along with declarative referential integrity support. InnoDB is included by default in most binaries distributed by MySQL AB.
