The Advanced tab gives you swift access to a set of advanced features, among them the Memcached distributed memory caching system and the Varnish Cache web accelerator, which will help you optimize your websites and applications without the need to move away from the Control Panel. Depending on the website hosting package, these tools are either added by default or are offered in the form of easily gettable upgrades. InnoDB and NodeJS support is available as well.
Varnish Cache is a web accelerator also known as an HTTP accelerator. You can install it in front of any 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 speed. One of the important attributes of Varnish Cache is the flexibility of its principal configuration mechanism, VCL, which permits you to determine how incoming requests should be handled.
Memcached is a generic memory caching system for increasing the load speed of dynamic database-driven sites. 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 traffic-hungry sites on the World Wide Web and is supported by popular CMSs like Joomla and WordPress.
InnoDB is the default storage engine for the MySQL open-source RDBMS. A storage engine is the principal software component that a DBMS uses to create, retrieve, modify and delete data from a database. Its latest edition features significant improvements in efficiency, reliability and usability. InnoDB offers the standard ACID-compliant transaction features, as well as foreign key support. InnoDB is included as standard in most binary distributions from MySQL AB.
