The Advanced tab provides you with fast access to an array of advanced features, among them the Memcached distributed memory caching system and the Varnish Cache web application accelerator, which will help you optimize your websites and apps without needing to move away from the hosting Control Panel. Depending on the website hosting plan, these features are either added by default or are offered in the form of easily gettable upgrades. InnoDB and NodeJS support is available too.
Varnish Cache is a web accelerator also known 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 very, very fast and will improve your web site's loading speed. One of the key advantages of Varnish Cache is the flexibility of its principal configuration mechanism, VCL, which enables you to define how incoming requests should be dealt with.
Memcached is a generic memory caching system for speeding up 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 distributed memory object caching system uses a two-tier architecture. The Memcached distributed memory caching system is employed by some of the most regularly visited websites on the web and is supported by famous web applications like Joomla and WordPress.
InnoDB is the default database engine for the MySQL open-source relational database management system. A storage engine is the main software component that a DBMS uses to create, read, modify and delete data from a database. Its latest release features significant improvements in efficiency, stability and functionality. InnoDB provides the standard ACID-compliant database transaction properties, as well as declarative referential integrity support. It is included as standard in most binary distributions from MySQL AB.
