Hepsia Advanced Features
The Advanced tab provides you with quick access to an array of advanced tools, among them the Memcached memory caching system and the Varnish Cache web accelerator, which will help you optimize your web sites and apps without needing to leave the Control Panel. Depending on the web hosting plan, these features are either included by default or are available in the form of easy-to-get upgrades. InnoDB and NodeJS support is available too.
Varnish
Varnish Cache is a web accelerator also called as a caching HTTP reverse proxy. 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 very, very fast and will boost the loading speed of your website. One of the main merits of Varnish Cache is the flexibility of its domain-specific language, VCL, which enables you to specify how incoming requests should be handled.
Memcached
Memcached is a generic memory object caching system for speeding up dynamic database-driven 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 distributed memory object caching system uses a client'server architecture. The Memcached distributed memory caching system is used by some of the most popular sites on the web and is supported by popular web apps like Joomla and WordPress.
Node.js
Node.js is a platform for writing highly scalable Internet applications. Built on Chrome's JavaScript runtime, Node.js uses an event-based, asynchronous input/output model that makes it lightweight and efficient, great for high-performance data-heavy applications. 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 database management system. A database engine is the main software component that a database management system uses to create, retrieve, update and delete data from a database. The latest edition of InnoDB features significant improvements in efficacy, reliability and usability. InnoDB provides the standard ACID database transaction properties, along with declarative referential integrity support. It is included as standard in most binary distributions from MySQL AB.
