The Advanced tab gives you quick access to a set of advanced features, among them the Memcached memory object caching system and the Varnish Cache web application accelerator, which will help you optimize your web sites and applications without having to log out of the hosting Control Panel. Based on the web hosting plan, these tools 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 famous as an HTTP accelerator. You can install it in front of any server that speaks HTTP and configure it to cache the contents. Varnish Cache is really, really fast and will boost the speed of your web site. One of the essential virtues of Varnish Cache is the flexibility of its configuration language, VCL, which allows you to determine how incoming requests should be tackled.
Memcached is a general-purpose memory object caching system for boosting the loading speed of dynamic database-driven websites. It is used to lower 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 system is employed by some of the most traffic-hungry web sites on the World Wide Web and is supported by popular CMSs like Joomla and WordPress.
InnoDB is the default storage engine for the MySQL open-source DBMS. A storage engine is the underlying software component that a database management system uses to create, retrieve, modify and delete data from a database. Its latest release features serious improvements in efficiency, stability and functionality. InnoDB provides the standard ACID-compliant database transaction features, as well as declarative referential integrity support. It is included by default in most binary distributions from MySQL AB.
