Hepsia Advanced Features
The Advanced tab gives you quick 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 hosting Control Panel. Depending on the web hosting package, these tools 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 server that speaks HTTP and configure it to cache the contents. Varnish Cache is very, very fast and will boost your site's speed. One of the important strengths of Varnish Cache is the flexibility of its configuration language, VCL, which permits you to choose how incoming requests should be handled.
Memcached
Memcached is a generic memory caching system for boosting the loading speed of dynamic database-powered websites. 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 system uses a client'server architecture. The Memcached system is employed by some of the most regularly visited websites on the Internet and is supported by popular web applications like Joomla and WordPress.
Node.js
Node.js is a software platform for writing highly scalable Internet apps. Built on Chrome's JavaScript runtime, Node.js uses an event-based, non-blocking input/output model that makes it lightweight and efficient, great for real-time data-intensive 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 storage engine is the principal software component that a DBMS uses to create, retrieve, update and delete data from a database. The latest edition of InnoDB offers substantial improvements in performance, dependability and functionality. InnoDB provides the standard ACID transaction features, along with declarative referential integrity support. It is included by default in most binaries distributed by MySQL AB.
