Hepsia Advanced Features
The Advanced tab grants you fast access to a set of advanced tools, among them the Memcached distributed memory caching system and the Varnish Cache web accelerator, which will help you optimize your sites and apps without needing to log out of the hosting Control Panel. Based 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 offered as well.
Varnish
Varnish Cache is a web accelerator also known as an HTTP accelerator. You can install it in front of any web server that speaks the HTTP protocol and configure it to cache the content. Varnish Cache is really, really fast and will boost the loading speed of your site. One of the key advantages of Varnish Cache is the flexibility of its principal configuration mechanism, VCL, which allows you to specify how incoming requests should be tackled.
Memcached
Memcached is a generic memory caching system for boosting the loading speed of dynamic database-powered web sites. It is used to reduce 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 memory object caching system uses a client'server architecture. The Memcached distributed memory caching system is employed by some of the most traffic-heavy sites on the World Wide Web and is supported by famous Content Management Systems like Joomla and WordPress.
Node.js
Node.js is a software platform for writing highly scalable network applications. Written in JavaScript, Node.js uses an event-based, non-blocking input/output model that makes it lightweight and effective, excellent for real-time content-intensive applications. Node.js uses Google's V8 JavaScript engine, libUV, and several built-in libraries.
InnoDB
InnoDB is the default storage engine for the MySQL open-source database management system. A storage engine is the main software component that a DBMS uses to create, read, modify and delete data from a database. The latest version of InnoDB offers substantial improvements in performance, stability and usability. InnoDB offers the standard ACID transaction properties, as well as referential integrity support. InnoDB is included by default in most binary distributions from MySQL AB.
