The Advanced tab provides you with fast access to a set of advanced tools, among them the Memcached memory object caching system and the Varnish Cache web accelerator, which will help you optimize your sites and apps without the need to leave the Control Panel. Based on the 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 as well.
Varnish Cache is a web application accelerator also famous as an HTTP accelerator. 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 increase the loading speed of your web site. One of the chief advantages of Varnish Cache is the flexibility of its domain-specific language, VCL, which permits you to specify how incoming requests should be handled.
Memcached is a general-purpose memory caching system for increasing the speed of dynamic database-driven sites. It is used to decrease 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 system is used by some of the most regularly visited websites on the World Wide Web and is supported by popular web applications like Joomla and WordPress.
InnoDB is the default database engine for the MySQL open-source DBMS. A database engine is the principal software component that a DBMS uses to create, read, update and delete data from a database. Its latest version features substantial improvements in efficiency, security and functionality. InnoDB offers the standard ACID-compliant transaction features, along with foreign key support. It is included as standard in most binary distributions from MySQL AB.
