The Advanced tab gives you quick access to a set of advanced tools, among them the Memcached distributed memory object caching system and the Varnish Cache web application accelerator, which will help you optimize your sites and apps without needing to leave the hosting Control Panel. Depending on the web hosting package, these features are either included by default or are available in the form of easy-to-get upgrades. InnoDB and NodeJS support is offered too.
Varnish Cache is a web accelerator also popular 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 really, really fast and will increase your website's loading speed. One of the chief attributes of Varnish Cache is the flexibility of its domain-specific language, VCL, which enables you to choose how incoming requests should be handled.
Memcached is a generic memory caching system for increasing the loading speed of dynamic database-driven sites. It is used to reduce 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 two-tier architecture. The Memcached distributed memory caching system is employed by some of the most popular web sites on the Internet and is supported by famous web apps like Joomla and WordPress.
InnoDB is the default database engine for the MySQL open-source database management system. A database engine is the underlying software component that a database management system uses to create, retrieve, modify and delete data from a database. The latest version of InnoDB features significant improvements in efficiency, reliability and usability. InnoDB provides the standard ACID-compliant database transaction features, as well as declarative referential integrity support. It is included by default in most binaries distributed by MySQL AB.
