Based on Gartner’s definition of middleware, IBM has once again been named the overall market share leader in the software category – the 11th consecutive year it has taken the top slot.

The rankings are based on total worldwide revenue for 2011.

According to the Gartner report, IBM was the leading software vendor with 32,1% market share, extending its lead to nearly double that of its closest competitor.  According to the research organisation, IBM grew 12,4% in 2011, faster than the overall market. The worldwide application infrastructure and middleware software market grew 9,9% to $19,4-billion, says Gartner.

Besides its overall lead, according to the report, IBM holds the number one market share position in key sub-markets growing faster than the overall IT market.

For example, the Business Process Management Suite (BPMS) segment grew at 11,2% in 2011, Gartner says. IBM was named the number one vendor in BPMS software with a 27,1% share; almost triple that of its closest competitor. BPMS software enables companies to develop and implement processes that help their businesses be more agile and grow.

Gartner reports that IBM continues to be number one in other growing and key areas including the Enterprise Service Bus Suites, Message Oriented Middleware Market, the Transaction Processing Monitor market and Integration Appliances.  Gartner also reported double digit growth by IBM for the Portal Products and User Interaction segment  IBM’s continued market share leadership in middleware has been a key reason for the company’s strong growth.

“We believe the newest Gartner report reflects IBM’s continued and growing lead in business integration middleware,” says Marie Wieck, GM, IBM Application and Middleware. “We are continually integrating and accelerating the capabilities we provide clients so that they can expand into key growth areas such as BPM, business analytics, security, mobile and cloud. The growth in our marketshare illustrates the success of this strategy.”

IBM has also been named the number one share holder in the worldwide application development software market according to Gartner with 24% of the market.  Gartner reports that IBM continues to lead in key and growing segments including the Distributed Software Change & Configuration Management, Requirements Elicitation and Management, Design and Java Platform AD Tools, and realised 25% growth in the Security Testing (DAST & SAST) market.
