This IDC study examines the enterprise service bus (ESB) and connectivity middleware market from 2005 to 2009. Revenue and market share of the leading vendors are provided as well as revenue by geography.
"We believe significant change in architectures and approaches to enterprise computing will increase the importance of ESBs over the next several years," according to Maureen Fleming, program director, Business Process Management and Middleware. "Technologically advanced enterprises are lightening up their applications and relying more on developing only net-new functionality and utilizing existing capabilities to compose an application. ESBs are essential in this scenario."
