Hepsia Advanced Features
The Advanced tab gives you fast 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 websites and applications without needing to move away from the Control Panel. Based on the hosting package, these features are either added by default or are offered in the form of easy-to-get upgrades. InnoDB and NodeJS support is available too.
Varnish Cache is a web application accelerator also referred to as a caching HTTP reverse proxy. You can install it in front of any server that speaks the HTTP protocol and configure it to cache the content. Varnish Cache is really, really fast and will boost the speed of your site. One of the important attributes of Varnish Cache is the flexibility of its principal configuration mechanism, VCL, which permits you to define how incoming requests should be tackled.
Memcached is a generic distributed memory object caching system for increasing the load speed of dynamic database-driven 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 caching system uses a two-tier architecture. The Memcached memory object caching system is employed by some of the most traffic-heavy web sites on the web and is supported by popular CMSs like Joomla and WordPress.
InnoDB is the default database engine for the MySQL open-source database management system. A storage engine is the main software component that a DBMS uses to create, retrieve, modify and delete data from a database. The latest release of InnoDB offers serious improvements in performance, stability and usability. InnoDB provides the standard ACID database transaction features, as well as referential integrity support. InnoDB is included by default in most binary distributions from MySQL AB.
