Hepsia Advanced Features
The Advanced tab provides you with quick access to a set of advanced features, among them the Memcached memory caching system and the Varnish Cache web accelerator, which will help you optimize your web sites and applications without needing to log out of the hosting Control Panel. Depending on the 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 as well.
Varnish
Varnish Cache is a web application accelerator also referred to 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 very, very fast and will boost the speed of your site. One of the essential features of Varnish Cache is the flexibility of its configuration language, VCL, which allows you to determine how incoming requests should be tackled.
Memcached
Memcached is a generic memory caching system for boosting the speed of dynamic database-powered 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 caching system uses a two-tier architecture. The Memcached distributed memory object caching system is employed by some of the most popular sites on the World Wide Web and is supported by popular web apps like Joomla and WordPress.
Node.js
Node.js is a software platform for writing scalable network applications. Built on Chrome's JavaScript runtime, Node.js uses an event-based, non-blocking I/O model that makes it lightweight and effective, perfect for real-time data-rich network apps. Node.js uses Google's V8 JavaScript engine, libUV, and a number of built-in libraries.
InnoDB
InnoDB is the default storage engine for the MySQL open-source DBMS. A database engine is the main software component that a DBMS uses to create, read, update and delete data from a database. Its latest version features substantial improvements in performance, reliability and functionality. InnoDB provides the standard ACID-compliant database transaction properties, along with referential integrity support. It is included as standard in most binaries distributed by MySQL AB.
