The Advanced tab provides you with quick access to a set of advanced features, among them the Memcached memory object caching system and the Varnish Cache web accelerator, which will help you optimize your websites and applications without needing to log out of the Control Panel. Depending on the website hosting plan, these features 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 famous as an HTTP accelerator. You can install it in front of any server that speaks HTTP and configure it to cache the contents. Varnish Cache is really, really fast and will make your website load much faster. One of the key features of Varnish Cache is the flexibility of its domain-specific language, VCL, which enables you to choose how incoming requests should be tackled.
Memcached is a generic memory caching system for boosting the load speed of dynamic database-powered websites. 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 distributed memory object caching system uses a client/server architecture. The Memcached distributed memory caching system is used by some of the most frequently visited sites on the Internet and is supported by famous CMSs like Joomla and WordPress.
InnoDB is the default storage engine for the MySQL open-source relational database management system. A storage engine is the principal software component that a DBMS uses to create, retrieve, update and delete data from a database. The latest edition of InnoDB offers serious improvements in efficacy, dependability and functionality. InnoDB offers the standard ACID transaction properties, along with declarative referential integrity support. It is included by default in most binary distributions from MySQL AB.
