Hepsia Advanced Features
The Advanced tab provides you with quick access to a set of advanced features, among them the Memcached distributed memory caching system and the Varnish Cache web accelerator, which will help you optimize your sites and apps without needing to leave the hosting Control Panel. Based on the hosting plan, these tools are either added by default or are available in the form of easily gettable upgrades. InnoDB and NodeJS support is available as well.
Varnish Cache is a web accelerator also called as a caching HTTP reverse proxy. You can install it in front of any server that speaks HTTP and configure it to cache the contents. Varnish Cache is very, very fast and will improve the speed of your web site. One of the chief pluses of Varnish Cache is the flexibility of its domain-specific language, VCL, which permits you to specify how incoming requests should be tackled.
Memcached is a generic distributed memory caching system for boosting the loading speed of dynamic database-driven websites. It is used to lower the number of times an external data source (such as a database or API) is read by caching data and objects in RAM. The Memcached memory object caching system uses a client'server architecture. The Memcached distributed memory object caching system is used by some of the most traffic-hungry sites 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 RDBMS. A database engine is the main software component that a DBMS uses to create, retrieve, modify and delete data from a database. Its latest release features considerable improvements in efficiency, stability and usability. InnoDB provides the standard ACID database transaction attributes, as well as referential integrity support. InnoDB is included by default in most binaries distributed by MySQL AB.
