Hepsia Advanced Features
The Advanced tab gives you fast access to a set of advanced features, 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 log out of the hosting Control Panel. Based on the website hosting package, these features are either added by default or are available in the form of easily gettable upgrades. InnoDB and NodeJS support is offered too.
Varnish
Varnish Cache is a web application accelerator also called as an HTTP accelerator. You can install it in front of any server that speaks HTTP and configure it to cache the contents. Varnish Cache is really, really fast and will increase the loading speed of your site. One of the key features of Varnish Cache is the flexibility of its configuration language, VCL, which enables you to specify how incoming requests should be dealt with.
Memcached
Memcached is a general-purpose distributed memory object caching system for boosting the loading speed of dynamic database-powered web sites. 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 memory caching system uses a client'server architecture. The Memcached distributed memory caching system is employed by some of the most traffic-intensive web sites on the Internet and is supported by famous web apps like Joomla and WordPress.
Node.js
Node.js is a software system for building highly scalable network applications. Built on Chrome's JavaScript runtime, Node.js uses an event-based, asynchronous I/O model that makes it lightweight and effective, suitable for high-performance data-rich network apps. Node.js uses Google's V8 JavaScript engine, libUV, and several built-in libraries.
InnoDB
InnoDB is the default database engine for the MySQL open-source DBMS. A storage engine is the main software component that a DBMS uses to create, read, update and delete data from a database. Its latest release offers considerable improvements in efficiency, security and usability. InnoDB offers the standard ACID-compliant database transaction properties, as well as declarative referential integrity support. It is included as standard in most binaries distributed by MySQL AB.
