Advanced Features
The Advanced tab grants you quick access to an array of advanced features, among them the Memcached distributed memory object caching system and the Varnish Cache web accelerator, which will help you optimize your sites and apps without the need to move away from the web hosting Control Panel. Based on the website hosting plan, these tools are either included by default or are available in the form of easy-to-get upgrades. InnoDB and NodeJS support is offered too.
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 boost your site's loading speed. One of the essential pluses of Varnish Cache is the flexibility of its domain-specific language, VCL, which permits you to specify how incoming requests should be dealt with.
Memcached
Memcached is a general-purpose memory object caching system for boosting the load speed of dynamic database-driven web sites. It is used to lower 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 caching system uses a client/server architecture. The Memcached memory caching system is used by some of the most popular websites on the Internet and is supported by popular web applications like Joomla and WordPress.
Node.js
Node.js is a software platform for building highly scalable Internet apps. Written in JavaScript, Node.js uses an event-based, non-blocking I/O model that makes it lightweight and effective, great for real-time content-rich Internet apps. Node.js uses Google's V8 JavaScript engine, libUV, and a number of in-built libraries.
InnoDB
InnoDB is the default database engine for the MySQL open-source database management system. A storage 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 efficiency, security and functionality. InnoDB provides the standard ACID-compliant transaction properties, along with foreign key support. It is included by default in most binaries distributed by MySQL AB.
