Hepsia Advanced Features
The Advanced tab gives you fast access to a set of advanced features, among them the Memcached distributed 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. Based on the web hosting package, these features 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 application accelerator also famous 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 contents. Varnish Cache is really, really fast and will increase your site's loading speed. One of the main strengths of Varnish Cache is the flexibility of its domain-specific language, VCL, which allows you to determine how incoming requests should be tackled.
Memcached is a general-purpose memory caching system for increasing the speed of dynamic database-driven sites. 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 memory object caching system uses a two-tier architecture. The Memcached memory object caching system is used by some of the most traffic-hungry sites on the Internet and is supported by famous Content Management Systems like Joomla and WordPress.
InnoDB is the default storage engine for the MySQL open-source relational database management system. A storage engine is the underlying software component that a DBMS uses to create, read, update and delete data from a database. Its latest release offers substantial improvements in efficacy, reliability and usability. InnoDB offers 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.
