How Ibm Has Expanded Websphere

摘要

IBM is the 500lb gorilla in the middleware room. The firm's sheer size, along with its experience in applications, operational systems and legacy application integration, makes it a formidable force in the middleware market. Big Blue has considerable experience, having developed a range of legacy products that originated in the mainframe era, so it has a heritage in managing application integration in high-volume, mission-critical environments. Its CICS transaction manager has been selling since the late 1960s. These days, everything to do with middleware at IBM revolves around its Websphere brand. Introduced in 1998 as little more than an application server, it has expanded over the past 10 years to encompass more or less all parts of the middleware stack, from application server through to business process modelling. Some legacy products have been absorbed into Websphere (MQ Series became Websphere MQ).
