Advanced Features
The Advanced tab provides you with quick access to an array of advanced tools, among them the Memcached memory caching system and the Varnish Cache web accelerator, which will help you optimize your web sites and applications without having to log out of the hosting Control Panel. Based on the hosting package, these tools are either included by default or are available in the form of easy-to-get upgrades. InnoDB and NodeJS support is available too.
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 HTTP and configure it to cache the content. Varnish Cache is really, really fast and will improve your site's speed. One of the chief pluses of Varnish Cache is the flexibility of its principal configuration mechanism, VCL, which permits you to determine how incoming requests should be dealt with.
Memcached
Memcached is a general-purpose memory caching system for increasing the loading speed of dynamic database-powered sites. It is used to reduce 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 client'server architecture. The Memcached distributed memory caching system is used by some of the most popular sites on the web and is supported by famous Content Management Systems like Joomla and WordPress.
Node.js
Node.js is a platform for writing highly scalable Internet applications. Built on Chrome's JavaScript runtime, Node.js uses an event-driven, asynchronous input/output model that makes it lightweight and effective, excellent for high-performance content-heavy 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 DBMS. A database engine is the principal software component that a DBMS uses to create, read, modify and delete data from a database. The latest edition of InnoDB features considerable improvements in efficacy, security and functionality. InnoDB provides the standard ACID-compliant database transaction features, as well as foreign key support. It is included as standard in most binaries distributed by MySQL AB.
