The Advanced tab provides you with swift access to an array of advanced tools, among them the Memcached distributed memory object 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 Control Panel. Depending on the hosting package, these tools are either included by default or are offered in the form of easy-to-get upgrades. InnoDB and NodeJS support is available too.
Varnish Cache is a web application accelerator also referred to as a caching HTTP reverse proxy. You can install it in front of any web server that speaks the HTTP protocol and configure it to cache the content. Varnish Cache is really, really fast and will increase your website's speed. One of the chief virtues of Varnish Cache is the flexibility of its principal configuration mechanism, VCL, which enables you to specify how incoming requests should be tackled.
Memcached is a general-purpose distributed memory object caching system for increasing the load speed of dynamic database-powered websites. It is used to lower 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 system uses a client/server architecture. The Memcached distributed memory caching system is used by some of the most frequently visited websites on the Internet and is supported by popular web applications like Joomla and WordPress.
InnoDB is the default storage engine for the MySQL open-source DBMS. A storage engine is the underlying software component that a database management system uses to create, retrieve, modify and delete data from a database. The latest release of InnoDB offers serious improvements in efficiency, stability and usability. InnoDB offers the standard ACID-compliant database transaction features, along with declarative referential integrity support. It is included as standard in most binaries distributed by MySQL AB.
