– 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.”
Scalability
OS —————
In-Process Transport
Inter-Process Transport

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.”
Distributed Systems
Nanomsg is all about communication and coordination
