The Advanced tab gives you swift access to an array of advanced features, among them the Memcached memory object caching system and the Varnish Cache web accelerator, which will help you optimize your websites and apps without needing to move away from the Control Panel. Depending 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 accelerator also referred to 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 content. Varnish Cache is really, really fast and will speed up your web site. One of the important attributes of Varnish Cache is the flexibility of its principal configuration mechanism, VCL, which enables you to define how incoming requests should be handled.
Memcached is a general-purpose distributed memory caching system for increasing the load speed of dynamic database-powered 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 used by some of the most frequently visited sites on the web and is supported by popular CMSs like Joomla and WordPress.
InnoDB is the default database engine for the MySQL open-source RDBMS. A database engine is the primary software component that a DBMS uses to create, read, modify and delete data from a database. The latest release of InnoDB features serious improvements in performance, reliability and functionality. InnoDB provides the standard ACID database transaction features, along with foreign key support. InnoDB is included as standard in most binary distributions from MySQL AB.
