News: dynaTrace acquired by Compuware???

  1. dynaTrace acquired by Compuware??? (2 messages)

    Compuware has acquired dynaTrace for $256 million, announced this morning. The primary focus seems to be on Compuware integrating dynatrace into their Gomez APM; dynaTrace has been making moves into testing performance loads across the whole stack, and Gomez focuses on the web side of things.

    The whole idea of the cloud has thrown a loop into performance testing.

    You used to be able to test with two or three machines: one for database, one for the app, one to run the tests on. Maybe less if the database didn't do a lot, so you'd run mysql on the server too, and if your client app was simple enough you could run everything on one machine, looking for application hotspots.

    But the real world doesn't work that way for long; you really have to factor in network too, so your app might not have an application hotspot but the network configuration might introduce a problem.

    Apps like dynaTrace give focus to the connection points between components, so while hotspots are still important, it's more important to know which part of your application is taking time or introducing errors. It does transaction tracking, so you can see what data caused a problem, in what part of your application architecture, and problems can be defined how you want (so if a component takes a second longer than it should, you can see that it happened and what data caused that.)

    dynaTrace also uses a queueing model itself for tracing data, so you can deploy it on production servers without negatively impacting your performance.

    Anyway, cloud has screwed up the traditional performance testing idea because companies aren't controlling every aspect of their production environments any more. If you use external clouds like GAE or Azure, then you often don't even know for sure how many machines your running on at any given moment, or what the capabilities of those machines are. You just think it's enough and move on.

    So apps like Gomez (from CompuWare) and dynaTrace are going to be working together in the compuware product line to help companies see what their cloud applications are doing and how they're performing and what they're doing.

    Hello,

    When you think about , what do you think of first? Which aspects of  are important, which are essential, and which ones can you take or leave? You be the judge.

     

    If you don't have accurate details regarding, pass4sure then you might make a bad choice on the subject. Don't let that happen: keep reading.

    Headquartered in suburban Boston, dynaTrace employs 180 people around the world. pass4sure 000-087 Substantially all of these employees, including the leadership team, are expected to remain with Compuware. pass4sure HP0-S28 dynaTrace has a 92-percent win rate and a five-year CAGR of 125 percent because its unique PurePath technology solves the multi-billion dollar problem of optimizing application performance in a different and better way.  

    There's a lot to understand about pass4sure 642-741 We were able to provide you with some of the facts above, but there is still plenty more to write about in subsequent articles.
