The worldwide application infrastructure and middleware (AIM) software market revenue totaled $14.1 billion in 2007, a 12.9 percent increase from 2006 revenue of $12.5 billion, according to Gartner, Inc. The market was primarily driven by strong growth in emerging market segments, such as enterprise service buses (ESBs) and business process management suites (BPMS).
The AIM market can be primarily characterized by three overall market forces. The market is demonstrating resilience with several mature segments still evolving and growing. In addition, vendors are shifting their traditional application infrastructure and middleware products mix toward ESBs and BPMS in response to the strong demand for products that support service-oriented architecture (SOA) and process-centric applications. Thirdly, the globalization and internationalization of companies are driving B2B integration requirements and sophistication.
In 2007, the top five vendors held more than 50 percent of the overall AIM market and are slowly eroding market shares from the smaller vendors primarily through acquisitions and expansion of their middleware suites offerings. IBM maintained its leading position and accounted for 28.9 percent of the total software revenue.
Integration Appliances, one of the 11 segments in which Gartner divides the AIM market was the fastest growing segment which saw an increase of 64 percent in 2007, although growing from a small installed base. ESBs held the No.2 position with a solid 39 percent growth continuing to benefit from the increasing demand for SOA.
From a regional perspective, North America and Western Europe remained the largest regions worldwide followed by Japan and Asia Pacific. Asia Pacific was the fastest-growing region with 25.4 percent growth in 2007. The performance was fostered by the rapid modernization of IT infrastructure and emerging small medium business markets in China and India.
