The Advanced tab provides you with quick access to a set of advanced features, among them the Memcached memory caching system and the Varnish Cache web accelerator, which will help you optimize your websites and apps without having to leave the web hosting Control Panel. Based on the web hosting plan, these features are either included 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 known 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 content. Varnish Cache is very, very fast and will increase the speed of your website. One of the chief advantages of Varnish Cache is the flexibility of its configuration language, VCL, which permits you to determine how incoming requests should be handled.
Memcached is a general-purpose distributed memory object caching system for boosting the loading speed of dynamic database-driven websites. It is used to decrease 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 distributed memory caching system uses a two-tier architecture. The Memcached distributed memory object caching system is employed by some of the most traffic-hungry websites on the World Wide Web and is supported by popular web apps like Joomla and WordPress.
InnoDB is the default storage engine for the MySQL open-source RDBMS. A storage engine is the underlying software component that a database management system uses to create, retrieve, modify and delete data from a database. The latest release of InnoDB offers substantial improvements in performance, dependability and functionality. InnoDB provides the standard ACID transaction properties, as well as referential integrity support. InnoDB is included by default in most binary distributions from MySQL AB.
