Varnish Cache is a web application 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 improve your site's speed. One of the chief strengths of Varnish Cache is the flexibility of its principal configuration mechanism, VCL, which enables you to determine how incoming requests should be dealt with.
Memcached is a generic distributed memory object caching system for increasing the speed of dynamic database-powered sites. It is used to decrease 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 client'server architecture. The Memcached distributed memory object caching system is used by some of the most frequently visited sites on the World Wide Web and is supported by famous web apps like Joomla and WordPress.
InnoDB is the default database engine for the MySQL open-source database management system. A database engine is the underlying software component that a DBMS uses to create, read, update and delete data from a database. The latest edition of InnoDB features substantial improvements in efficiency, reliability and usability. InnoDB provides the standard ACID transaction properties, as well as declarative referential integrity support. InnoDB is included as standard in most binary distributions from MySQL AB.
