The Advanced tab grants you quick 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 web sites and apps without the need to leave the hosting Control Panel. Based on the web hosting plan, these tools are either added 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 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 contents. Varnish Cache is very, very fast and will increase the loading speed of your web site. One of the important pluses of Varnish Cache is the flexibility of its domain-specific language, VCL, which enables you to specify how incoming requests should be dealt with.
Memcached is a generic memory caching system for boosting the loading speed of dynamic database-powered web 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 object caching system uses a client'server architecture. The Memcached system is used by some of the most popular websites on the Internet and is supported by popular CMSs like Joomla and WordPress.
InnoDB is the default storage engine for the MySQL open-source RDBMS. A storage engine is the principal software component that a DBMS uses to create, retrieve, update and delete data from a database. Its latest edition offers significant improvements in performance, dependability and usability. InnoDB provides the standard ACID-compliant transaction properties, as well as foreign key support. InnoDB is included by default in most binaries distributed by MySQL AB.
