Varnish
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 content. Varnish Cache is really, really fast and will improve the speed of your site. One of the essential pluses of Varnish Cache is the flexibility of its domain-specific language, VCL, which enables you to determine how incoming requests should be handled.
Memcached
Memcached is a general-purpose distributed memory caching system for boosting the speed of dynamic database-powered web 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 system uses a client'server architecture. The Memcached distributed memory object caching system is used by some of the most frequently visited websites on the World Wide Web and is supported by famous CMSs like Joomla and WordPress.
Node.js
Node.js is a platform for writing scalable Internet apps. Written in JavaScript, Node.js uses an event-based, asynchronous I/O model that makes it lightweight and efficient, great for real-time data-heavy Internet applications. Node.js uses Google's V8 JavaScript engine, libUV, and several built-in libraries.
InnoDB
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 database management system uses to create, read, update and delete data from a database. The latest release of InnoDB features substantial improvements in efficiency, reliability and usability. InnoDB offers the standard ACID database transaction attributes, along with declarative referential integrity support. InnoDB is included by default in most binaries distributed by MySQL AB.
