The Advanced tab gives you quick access to a set of advanced features, among them the Memcached distributed memory object caching system and the Varnish Cache web accelerator, which will help you optimize your web sites and applications without having to leave the web hosting Control Panel. Depending on the website hosting package, these features are either added by default or are offered in the form of easy-to-get upgrades. InnoDB and NodeJS support is available too.
Varnish Cache is a web accelerator also famous as an HTTP accelerator. You can install it in front of any server that speaks HTTP and configure it to cache the content. Varnish Cache is really, really fast and will boost the loading speed of your web site. One of the chief advantages of Varnish Cache is the flexibility of its configuration language, VCL, which allows you to define how incoming requests should be dealt with.
Memcached is a general-purpose distributed memory caching system for boosting the loading speed of dynamic database-driven 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 memory caching system is employed by some of the most traffic-hungry websites on the Internet and is supported by famous Content Management Systems like Joomla and WordPress.
InnoDB is the default storage engine for the MySQL open-source RDBMS. A storage engine is the primary software component that a database management system uses to create, read, update and delete data from a database. The latest version of InnoDB features serious improvements in efficiency, security and functionality. InnoDB provides the standard ACID-compliant database transaction attributes, as well as declarative referential integrity support. It is included as standard in most binaries distributed by MySQL AB.
