The Advanced tab grants 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 having to move away from the Control Panel. Based on the website hosting package, these tools are either included by default or are available in the form of easily gettable upgrades. InnoDB and NodeJS support is offered as well.
Varnish Cache is a web application accelerator also popular 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 improve your web site's speed. One of the major virtues of Varnish Cache is the flexibility of its principal configuration mechanism, VCL, which allows you to choose how incoming requests should be tackled.
Memcached is a generic memory caching system for boosting the speed of dynamic database-powered websites. 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 memory caching system uses a client'server architecture. The Memcached distributed memory caching system is used by some of the most traffic-intensive websites on the Internet and is supported by famous CMSs like Joomla and WordPress.
InnoDB is the default storage engine for the MySQL open-source relational database management system. A storage engine is the primary software component that a DBMS uses to create, read, update and delete data from a database. Its latest version features substantial improvements in efficiency, security and usability. InnoDB provides the standard ACID-compliant database transaction attributes, as well as foreign key support. It is included by default in most binary distributions from MySQL AB.
