IT integration is an important but often complex aspect of IT strategy, and is essential to any organisation that require efficient sharing of information between different products sourced from many suppliers. Every major vendor has their own integration software and middleware offerings, including messaging and enterprise application integration, and making the right choice for your organisation is critical.
Middleware technologies are often employed to eliminate the pain of integration. A middleware solution is essentially a layer between two systems that makes it easy for the two to communicate. It can be considered the glue that holds together applications, making seamless connectivity possible without requiring the two applications to communicate directly.
