An integration appliance can be regarded as a combination of hardware and software that fulfills a specific integration purpose, such as enabling the partially predefined integration of certain applications together with new ones. It is not uncommon to see packaged integration, packaged processes, and SOA governance mechanisms and technologies alongside traditional appliance technologies, such as acceleration, transformation, XML parsing and security features, such as firewalls and packet inspection. An appliance can be regarded as one type of deployment mechanism, along with the more traditional packaged software, SaaS and hosted models.
