Explain the relationship of ESB technology with EAI and SOA?

Question

Can anyone explain the relationship of ESB technology with EAI and SOA? and give me some examples.

Answer 1

EAI is an integration framework composed of a group of technologies and services which form a middleware/ESB to enable integration of systems and applications within an enterprise, and/or across enterprises.

ESB is software architecture model used for implementing communication between software applications in a service-oriented architecture (SOA).

Examples:

Oracle Services Bus (OSB)

IBM WebSphere Enterprise Service Bus:

SOA is an architectural pattern in which application components provide services to other components/clients via communication protocol (SOAP, REST).

SOA architecture is independent of any vendor, product or technology.
