CA is boosting its applications management portfolio by acquiring Wily Technology for $375m (£221m) in cash.
Wily's software monitors the performance of applications and allows companies to diagnose bottlenecks and other problems in systems.
CA will use Wily to provide customers with an application management platform to manage packaged and custom-made applications, said CA.
As CA has, up to now, concentrated on providing infrastructure management solutions, it will retain most of Wily’s 260-strong workforce to make sure it gets the best out of its new acquisition.
CA claimed Wily was the best applications management player in the market place and admitted that it had not previously fully focused on this market area.
Once the deal is completed, Wily will become a division of CA's Enterprise Systems Management business unit. CA said there was little overlap between CA’s limited application management solutions and Wily’s more extensive range.
Wily's chief executive officer Dick Williams is due to join CA to lead this division. Lewis Cirne, Wily's founder and chief technology officer, will also switch to CA.
