Hepsia Advanced Features
The Advanced tab gives you fast access to a set of advanced tools, among them the Memcached memory object caching system and the Varnish Cache web application accelerator, which will help you optimize your sites and applications without the need to move away from the Control Panel. Based on the web hosting package, these features are either included by default or are offered in the form of easily gettable upgrades. InnoDB and NodeJS support is offered too.
Varnish Cache is a web application accelerator also famous as an HTTP accelerator. You can install it in front of any web server that speaks the HTTP protocol and configure it to cache the content. Varnish Cache is really, really fast and will increase your site's speed. One of the key virtues of Varnish Cache is the flexibility of its domain-specific language, VCL, which enables you to define how incoming requests should be dealt with.
Memcached is a general-purpose distributed memory object caching system for boosting the load speed of dynamic database-driven 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 distributed memory object caching system uses a client'server architecture. The Memcached memory caching system is used by some of the most traffic-intensive web sites on the Internet and is supported by popular CMSs like Joomla and WordPress.
InnoDB is the default database engine for the MySQL open-source relational database management system. A storage engine is the underlying software component that a DBMS uses to create, retrieve, modify and delete data from a database. Its latest edition features significant improvements in efficacy, security and functionality. InnoDB provides the standard ACID-compliant transaction properties, as well as declarative referential integrity support. It is included as standard in most binaries distributed by MySQL AB.
