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 apps without needing to move away from the hosting Control Panel. Based on the hosting package, these tools are either added by default or are available in the form of easily gettable upgrades. InnoDB and NodeJS support is offered as well.
Varnish
Varnish Cache is a web accelerator also referred to as a caching HTTP reverse proxy. You can install it in front of any server that speaks the HTTP protocol and configure it to cache the content. Varnish Cache is very, very fast and will increase the speed of your website. One of the key virtues of Varnish Cache is the flexibility of its configuration language, VCL, which allows you to choose how incoming requests should be tackled.
Memcached
Memcached is a general-purpose distributed memory object caching system for increasing the load speed of dynamic database-powered web 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 distributed memory object caching system uses a client'server architecture. The Memcached distributed memory object caching system is employed by some of the most traffic-heavy sites on the 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. Built on Chrome's JavaScript runtime, Node.js uses an event-based, non-blocking I/O model that makes it lightweight and efficient, excellent for high-performance data-intensive 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 DBMS. A database engine is the underlying software component that a DBMS uses to create, retrieve, update and delete data from a database. Its latest release offers serious improvements in performance, security and usability. InnoDB offers the standard ACID-compliant database transaction attributes, along with declarative referential integrity support. InnoDB is included as standard in most binaries distributed by MySQL AB.
