Overview

The underlying principles of reactive applications inform overall system design.

Message-driven runtime.

Reactive System Tenets according to the Reactive Manifesto

• Responsiveness refers to the capability of the system to be consistently responsive to the user and never fail; it refers to the value brought by such systems.
• Resilience is the capability of the system to self-heal, and refers to form in which reactive systems are delivered.
• Elasticity is the capability of the system to scale out and up/ in and down across physical and cloud infrastructure refers to form in which reactive systems are delivered.
• Message-driven refers to the means used to implement reactive systems. A message-driven system is powered by means of asynchronous, non-blocking communication. This enables first and foremost isolation.
