– Characteristics of Scalability on Performance - André B. Bondi

“Scalability is the capability of a Process, OS or Network to handle a growing amount of work, or its

potential to be enlarged in order to accommodate that growth.”

Nanomsg provides the “Lego bricks” for building scalable and distributed

systems

– Distributed Systems: Concepts and Design (5th Edition) - Addison Wesley

“A distributed system is a model in which components located on networked computers communicate and coordinate their actions by

passing messages.”

Nanomsg is all about communication and coordination
