Hepsia Advanced Features
The Advanced tab gives you fast access to a set of advanced tools, among them the Memcached distributed memory object caching system and the Varnish Cache web accelerator, which will help you optimize your websites and apps without needing to log out of the Control Panel. Based on the website hosting package, these features are either included by default or are offered in the form of easy-to-get upgrades. InnoDB and NodeJS support is available too.
Varnish
Varnish Cache is a web application accelerator also famous 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 increase your website's loading speed. One of the main attributes of Varnish Cache is the flexibility of its principal configuration mechanism, VCL, which permits you to define how incoming requests should be tackled.
Memcached
Memcached is a general-purpose distributed memory caching system for increasing the load speed of dynamic database-driven web sites. It is used to reduce 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 client'server architecture. The Memcached distributed memory object caching system is employed by some of the most regularly visited websites on the web and is supported by popular web applications like Joomla and WordPress.
Node.js
Node.js is a platform for writing highly scalable network apps. Written in JavaScript, Node.js uses an event-based, non-blocking I/O model that makes it lightweight and efficient, suitable for real-time content-rich network apps. Node.js uses Google's V8 JavaScript engine, libUV, and a number of built-in libraries.
InnoDB
InnoDB is the default database engine for the MySQL open-source RDBMS. A storage engine is the underlying software component that a database management system uses to create, read, update and delete data from a database. Its latest release offers considerable improvements in efficiency, dependability and functionality. InnoDB offers the standard ACID-compliant database transaction properties, along with referential integrity support. It is included by default in most binary distributions from MySQL AB.
