Advanced Features
The Advanced tab gives you quick access to an array of advanced features, among them the Memcached memory object caching system and the Varnish Cache web application accelerator, which will help you optimize your websites and apps without having to leave the hosting Control Panel. Based on the hosting plan, these features are either added by default or are offered in the form of easy-to-get upgrades. InnoDB and NodeJS support is available 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 web server that speaks HTTP and configure it to cache the content. Varnish Cache is really, really fast and will improve the speed of your website. One of the important virtues of Varnish Cache is the flexibility of its principal configuration mechanism, VCL, which permits you to specify how incoming requests should be dealt with.
Memcached
Memcached is a general-purpose memory caching system for speeding up dynamic database-driven 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 object caching system uses a two-tier architecture. The Memcached memory caching system is used by some of the most regularly visited websites on the Internet and is supported by famous CMSs like Joomla and WordPress.
Node.js
Node.js is a software platform for writing highly scalable network apps. Built on Chrome's JavaScript runtime, Node.js uses an event-driven, asynchronous I/O model that makes it lightweight and efficient, ideal for high-performance content-rich 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 database management system. A storage engine is the underlying software component that a database management system uses to create, read, modify and delete data from a database. The latest release of InnoDB features substantial improvements in efficacy, dependability and functionality. InnoDB provides the standard ACID-compliant database transaction properties, as well as declarative referential integrity support. InnoDB is included by default in most binary distributions from MySQL AB.
