The Advanced tab gives you fast access to a set of advanced features, among them the Memcached distributed memory object caching system and the Varnish Cache web application accelerator, which will help you optimize your sites and apps without the need to leave the Control Panel. Depending on the web hosting plan, these features are either included by default or are offered in the form of easily gettable upgrades. InnoDB and NodeJS support is offered as well.
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 the HTTP protocol and configure it to cache the contents. Varnish Cache is really, really fast and will increase your web site's loading speed. One of the chief virtues of Varnish Cache is the flexibility of its configuration language, VCL, which enables you to specify how incoming requests should be handled.
Memcached is a generic distributed memory caching system for increasing the loading speed of dynamic database-driven 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 object caching system uses a client/server architecture. The Memcached memory object caching system is employed by some of the most regularly visited websites on the web and is supported by popular web applications like Joomla and WordPress.
InnoDB is the default storage engine for the MySQL open-source database management system. A database engine is the main software component that a DBMS uses to create, read, modify and delete data from a database. The latest edition of InnoDB features significant improvements in efficacy, reliability and functionality. InnoDB provides the standard ACID-compliant database transaction features, along with foreign key support. InnoDB is included by default in most binaries distributed by MySQL AB.
