Hepsia Advanced Features
The Advanced tab gives you quick access to a set of advanced tools, among them the Memcached memory caching system and the Varnish Cache web application accelerator, which will help you optimize your web sites and apps without the need to log out of the hosting Control Panel. Based on the web hosting package, these features are either added by default or are offered in the form of easily gettable upgrades. InnoDB and NodeJS support is offered as well.
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 the HTTP protocol and configure it to cache the contents. Varnish Cache is really, really fast and will improve the speed of your site. One of the main merits of Varnish Cache is the flexibility of its configuration language, VCL, which enables you to determine how incoming requests should be dealt with.
Memcached is a generic distributed memory caching system for boosting the loading speed of dynamic database-driven web sites. It is used to lower 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 two-tier architecture. The Memcached system is employed by some of the most traffic-heavy sites on the Internet and is supported by popular Content Management Systems like Joomla and WordPress.
InnoDB is the default database engine for the MySQL open-source relational database management system. A database engine is the main software component that a DBMS uses to create, read, update and delete data from a database. Its latest version offers substantial improvements in performance, security and usability. InnoDB provides the standard ACID-compliant transaction properties, as well as declarative referential integrity support. InnoDB is included as standard in most binaries distributed by MySQL AB.
