In 2005, XML appliances (or SOA appliances, as they came to be known) became increasingly associated with service-oriented architectures and more specifically the problem of governing SOA. The governance of SOA comes down to the control of how applications delivered as "services" can be shared with or called by other applications. Appliances became a popular way of controlling or governing SOA because addressed message security, availability and translation of data so that an application can call another application irrespective of the data format and security policies. Governance of SOA became so critical that Gartner published a dedicated "Integrated SOA Governance Technology Sets" Magic Quadrant on the topic that covered both SOA management and SOA appliances in March 2007 and most recently in March 2009.
