Hepsia Advanced Features
The Advanced tab provides you with 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 websites and applications without the need to log out of the Control Panel. Based on the web hosting plan, these tools are either added by default or are offered in the form of easy-to-get upgrades. InnoDB and NodeJS support is offered as well.
Varnish Cache is a web accelerator also popular 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 very, very fast and will make your website load much faster. One of the important features of Varnish Cache is the flexibility of its domain-specific language, VCL, which enables you to choose how incoming requests should be handled.
Memcached is a generic distributed memory object caching system for increasing the load speed of dynamic database-powered 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 caching system uses a client'server architecture. The Memcached system is employed by some of the most traffic-heavy web sites on the web and is supported by popular Content Management Systems like Joomla and WordPress.
InnoDB is the default storage engine for the MySQL open-source RDBMS. A storage engine is the underlying software component that a database management system uses to create, read, modify and delete data from a database. Its latest edition features serious improvements in efficiency, security and usability. InnoDB provides the standard ACID-compliant database transaction attributes, along with declarative referential integrity support. InnoDB is included as standard in most binary distributions from MySQL AB.
