FAQ about ESB Technology

1. What is ESB Technology?

ESB (Enterprise Service Bus) technology is a software architecture that facilitates interaction and communication between different applications in a service-oriented architecture (SOA). Think of it as a central nervous system for your IT infrastructure. ESB technology ensures seamless data exchange, promotes agility, and enhances scalability across diverse systems.

An ESB acts as a middleware solution, providing a standardized way for applications to communicate, regardless of their underlying technologies or protocols. It achieves this by offering services such as message transformation, routing, protocol conversion, and service orchestration. This promotes a loosely coupled architecture, where applications can interact without needing direct knowledge of each other.
