Hepsia Advanced Features
The Advanced tab grants 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 web sites and applications without having to log out of the Control Panel. Depending on the hosting plan, these tools are either included 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 famous as a caching HTTP reverse proxy. You can install it in front of any server that speaks HTTP and configure it to cache the content. Varnish Cache is really, really fast and will boost your web site's loading speed. One of the major pluses of Varnish Cache is the flexibility of its domain-specific language, VCL, which enables you to specify how incoming requests should be dealt with.
Memcached is a generic distributed memory object caching system for boosting the loading speed of dynamic database-driven web sites. 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 two-tier architecture. The Memcached system is used by some of the most traffic-heavy web sites on the World Wide Web and is supported by famous Content Management Systems like Joomla and WordPress.
InnoDB is the default database engine for the MySQL open-source database management system. A storage engine is the primary software component that a DBMS uses to create, retrieve, update and delete data from a database. The latest edition of InnoDB features substantial improvements in efficiency, reliability and usability. InnoDB provides the standard ACID transaction features, along with foreign key support. InnoDB is included as standard in most binaries distributed by MySQL AB.
