Advanced Features
The Advanced tab grants you fast access to an array of advanced tools, among them the Memcached distributed memory object caching system and the Varnish Cache web application accelerator, which will help you optimize your web sites and applications without needing to leave the Control Panel. Based on the website hosting package, these tools are either included by default or are available in the form of easily gettable upgrades. InnoDB and NodeJS support is available as well.
Varnish
Varnish Cache is a web application accelerator also known as a caching HTTP reverse proxy. You can install it in front of any web server that speaks the HTTP protocol and configure it to cache the content. Varnish Cache is really, really fast and will improve your website's speed. One of the important pluses of Varnish Cache is the flexibility of its domain-specific language, VCL, which allows you to determine how incoming requests should be tackled.
Memcached
Memcached is a general-purpose distributed memory object caching system for increasing the loading speed of dynamic database-powered sites. It is used to lower 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 memory caching system uses a client/server architecture. The Memcached distributed memory object caching system is used by some of the most popular sites on the Internet and is supported by popular Content Management Systems like Joomla and WordPress.
Node.js
Node.js is a platform for building highly scalable Internet applications. Written in JavaScript, Node.js uses an event-based, non-blocking input/output model that makes it lightweight and efficient, suitable for high-performance data-intensive Internet apps. Node.js uses Google's V8 JavaScript engine, libUV, and a number of in-built libraries.
InnoDB
InnoDB is the default storage engine for the MySQL open-source RDBMS. A storage 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 features considerable improvements in efficiency, reliability and usability. InnoDB offers the standard ACID-compliant transaction features, as well as referential integrity support. It is included by default in most binary distributions from MySQL AB.
