Hepsia Advanced Features
The Advanced tab grants you fast access to an array of advanced features, among them the Memcached memory object caching system and the Varnish Cache web application accelerator, which will help you optimize your websites and applications without needing to move away from the Control Panel. Depending on the hosting package, these tools are either added by default or are offered in the form of easily gettable upgrades. InnoDB and NodeJS support is available as well.
Varnish Cache is a web application accelerator also known as a caching HTTP reverse proxy. You can install it in front of any web server that speaks HTTP and configure it to cache the content. Varnish Cache is really, really fast and will improve your website's loading speed. One of the chief advantages of Varnish Cache is the flexibility of its domain-specific language, VCL, which enables you to define how incoming requests should be tackled.
Memcached is a general-purpose distributed memory caching system for increasing the speed of dynamic database-driven sites. It is used to decrease 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 system uses a two-tier architecture. The Memcached system is employed by some of the most traffic-heavy sites on the web and is supported by famous Content Management Systems like Joomla and WordPress.
InnoDB is the default database engine for the MySQL open-source RDBMS. A database engine is the primary software component that a database management system uses to create, read, modify and delete data from a database. Its latest release features substantial improvements in efficacy, security and functionality. InnoDB provides the standard ACID database transaction attributes, as well as foreign key support. It is included as standard in most binaries distributed by MySQL AB.
