Advanced Features
The Advanced tab grants you quick access to a set of advanced features, among them the Memcached distributed memory object caching system and the Varnish Cache web accelerator, which will help you optimize your websites and applications without having to leave the hosting Control Panel. Depending on the website hosting package, these features are either added by default or are offered in the form of easily gettable upgrades. InnoDB and NodeJS support is available too.
Varnish
Varnish Cache is a web application accelerator also referred to as an HTTP accelerator. 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 boost your site's loading speed. One of the chief strengths of Varnish Cache is the flexibility of its principal configuration mechanism, VCL, which allows you to determine how incoming requests should be dealt with.
Memcached
Memcached is a general-purpose memory object caching system for increasing the speed of dynamic database-powered web sites. It is used to decrease 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 system is employed by some of the most traffic-heavy websites on the World Wide Web and is supported by popular Content Management Systems like Joomla and WordPress.
Node.js
Node.js is a software platform for writing scalable network apps. Built on Chrome's JavaScript runtime, Node.js uses an event-driven, asynchronous I/O model that makes it lightweight and effective, suitable for high-performance data-rich applications. 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 relational database management system. A database engine is the principal software component that a DBMS uses to create, retrieve, modify and delete data from a database. The latest version of InnoDB offers significant improvements in efficacy, security and usability. InnoDB offers the standard ACID database transaction properties, as well as declarative referential integrity support. InnoDB is included as standard in most binaries distributed by MySQL AB.
