The Advanced tab grants you fast access to a set of advanced tools, among them the Memcached memory caching system and the Varnish Cache web application accelerator, which will help you optimize your web sites and apps without the need to move away from the hosting Control Panel. Based on the web hosting plan, these features are either added by default or are available in the form of easily gettable upgrades. InnoDB and NodeJS support is available too.
Varnish Cache is a web accelerator also called as an HTTP accelerator. 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 very, very fast and will boost your site's speed. One of the important virtues of Varnish Cache is the flexibility of its configuration language, VCL, which allows you to determine how incoming requests should be dealt with.
Memcached is a generic memory object caching system for boosting the loading 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 memory caching system uses a client'server architecture. The Memcached memory object caching system is employed by some of the most traffic-heavy web sites on the Internet and is supported by popular Content Management Systems like Joomla and WordPress.
InnoDB is the default database engine for the MySQL open-source RDBMS. A storage engine is the main software component that a database management system uses to create, retrieve, modify and delete data from a database. The latest version of InnoDB features serious improvements in performance, dependability and functionality. InnoDB provides the standard ACID-compliant transaction attributes, as well as referential integrity support. InnoDB is included by default in most binaries distributed by MySQL AB.
