Hepsia Advanced Features
The Advanced tab provides you with quick access to an array of advanced tools, among them the Memcached memory caching system and the Varnish Cache web application accelerator, which will help you optimize your websites and apps without the need to move away from the hosting Control Panel. Depending on the hosting plan, these features are either added by default or are available in the form of easily gettable upgrades. InnoDB and NodeJS support is available too.
Varnish Cache is a web application accelerator also called 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 improve your website's loading speed. One of the main advantages of Varnish Cache is the flexibility of its domain-specific language, VCL, which allows you to define how incoming requests should be tackled.
Memcached is a general-purpose memory object caching system for boosting the load speed of dynamic database-powered sites. It is used to decrease 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 caching system uses a two-tier architecture. The Memcached system is used by some of the most regularly visited web sites on the Internet and is supported by popular web applications like Joomla and WordPress.
InnoDB is the default database engine for the MySQL open-source RDBMS. A storage engine is the principal software component that a database management system uses to create, read, update and delete data from a database. Its latest release offers significant improvements in performance, stability and usability. InnoDB offers the standard ACID-compliant transaction features, as well as declarative referential integrity support. InnoDB is included by default in most binary distributions from MySQL AB.
