Hepsia Advanced Features
The Advanced tab provides you with fast access to a set of advanced features, among them the Memcached distributed memory caching system and the Varnish Cache web accelerator, which will help you optimize your websites and applications without the need to log out of the web hosting Control Panel. Based on the hosting plan, these features are either included by default or are offered in the form of easily gettable 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 improve the loading speed of your site. One of the main features of Varnish Cache is the flexibility of its configuration language, VCL, which allows you to determine how incoming requests should be handled.
Memcached
Memcached is a general-purpose memory caching system for increasing the loading speed of dynamic database-driven 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 distributed memory object caching system uses a two-tier architecture. The Memcached distributed memory caching system is used by some of the most frequently visited web sites on the World Wide Web and is supported by popular Content Management Systems like Joomla and WordPress.
Node.js
Node.js is a software system for building highly scalable Internet apps. Built on Chrome's JavaScript runtime, Node.js uses an event-driven, asynchronous I/O model that makes it lightweight and efficient, suitable for high-performance data-intensive applications. Node.js uses Google's V8 JavaScript engine, libUV, and a number of in-built libraries.
InnoDB
InnoDB is the default storage engine for the MySQL open-source database management system. A database engine is the primary software component that a DBMS uses to create, retrieve, update and delete data from a database. Its latest edition offers significant improvements in efficacy, stability and usability. InnoDB provides the standard ACID-compliant database transaction properties, as well as foreign key support. It is included as standard in most binary distributions from MySQL AB.
