4. What is Middleware?
• Software that is designed to help build large scale distributed
systems.
• Software that sits between systems.
• In strict technical terms, middleware is transport software that is
used to move information from one program to one or more other
programs, shielding the developer from dependencies on
communication protocols, operating systems, and hardware
platforms.
• Middleware allows isolated systems to “talk” to one another.
• Roughly half of IT budgets are spent on enabling systems to
communicate with one another.
