The Advanced tab grants you fast access to a set of advanced features, among them the Memcached distributed memory object caching system and the Varnish Cache web application accelerator, which will help you optimize your websites and apps without the need to move away from the web hosting Control Panel. Based on the hosting plan, these features are either included 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 application accelerator also known as a caching HTTP reverse proxy. You can install it in front of any web server that speaks HTTP and configure it to cache the contents. Varnish Cache is really, really fast and will boost your site's loading speed. One of the chief advantages of Varnish Cache is the flexibility of its principal configuration mechanism, VCL, which allows you to determine how incoming requests should be dealt with.
Memcached is a general-purpose distributed memory object 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 memory caching system uses a client'server architecture. The Memcached distributed memory object caching system is employed by some of the most traffic-hungry sites on the World Wide Web and is supported by popular web applications like Joomla and WordPress.
InnoDB is the default storage engine for the MySQL open-source database management system. A database engine is the principal software component that a database management system uses to create, retrieve, update and delete data from a database. The latest version of InnoDB features considerable improvements in efficiency, stability and usability. InnoDB provides the standard ACID transaction properties, as well as declarative referential integrity support. InnoDB is included as standard in most binaries distributed by MySQL AB.
