The Advanced tab provides you with swift access to a set of advanced features, among them the Memcached distributed memory caching system and the Varnish Cache web application accelerator, which will help you optimize your sites and apps without needing to log out of the Control Panel. Depending on the hosting package, these tools are either included by default or are offered in the form of easy-to-get upgrades. InnoDB and NodeJS support is available as well.
Varnish Cache is a web accelerator also called as an HTTP accelerator. You can install it in front of any server that speaks the HTTP protocol and configure it to cache the content. Varnish Cache is really, really fast and will increase your site's loading speed. One of the chief pluses 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 generic memory object caching system for boosting the loading speed of dynamic database-powered websites. 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 system uses a two-tier architecture. The Memcached system is used by some of the most frequently visited websites on the World Wide Web and is supported by popular Content Management Systems like Joomla and WordPress.
InnoDB is the default storage engine for the MySQL open-source relational database management system. A database engine is the primary software component that a DBMS uses to create, retrieve, modify and delete data from a database. The latest version of InnoDB features considerable improvements in efficacy, reliability and functionality. InnoDB offers the standard ACID transaction properties, along with referential integrity support. It is included by default in most binaries distributed by MySQL AB.
