The Advanced tab grants you quick access to an array of advanced features, among them the Memcached distributed memory caching system and the Varnish Cache web accelerator, which will help you optimize your sites and apps without having to leave the hosting Control Panel. Depending on the hosting package, these features are either added by default or are available in the form of easy-to-get upgrades. InnoDB and NodeJS support is available as well.
Varnish Cache is a web application accelerator also referred to 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 very, very fast and will boost your site's loading speed. One of the main strengths of Varnish Cache is the flexibility of its configuration language, VCL, which permits you to specify how incoming requests should be handled.
Memcached is a general-purpose distributed memory object caching system for boosting the load speed of 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 memory caching 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 Content Management Systems like Joomla and WordPress.
InnoDB is the default storage engine for the MySQL open-source relational database management system. A database engine is the main software component that a DBMS uses to create, retrieve, modify and delete data from a database. Its latest edition offers substantial improvements in efficacy, security and functionality. InnoDB offers the standard ACID-compliant database transaction features, along with referential integrity support. InnoDB is included as standard in most binaries distributed by MySQL AB.
