Top Stories by Andreas Grabner

Transformation to Continuous Innovation and Optimization Businesses have always had to transform to find better and more efficient ways to deliver value faster to their users, customers or consumers. The motivating factors are shorter lead times, automated and streamlined value flow, as well as reduction of overall costs and bound capital, requiring enterprises to transition to a continuous innovation and optimization model. Prominent examples can be found when studying the last decades in the automobile industry with Toyota and their way of optimizing and automating their end-to-end manufacturing process. It is also the most referenced story I hear when researching IT and Digital Transformation stories. The DevOps movement as well as literature around Continuous Integration, Delivery and Deployment all draw the analogies to the manufacturing world and explain what ... (more)

Challenges of Running Apps in “The Cloud”

Cloud Computing presents unique opportunities to companies to reduce costs, outsource non-core functions and scale costs to match demand. However, the Cloud also presents a new level of complexity that makes ensuring application performance in the Cloud a unique challenge, in particular  with the many different usage and deployment scenarios available. Perhaps the most popular present scenario uses the Cloud to perform certain tasks where  additional computational power is unavailable in a local environment, e.g.: running large scale load-tests or processing large amounts of in...

IE Compatibility View

A client of ours recently contacted me with the question: We use Keynote, WebPagetest and dynaTrace AJAX – but we get different results with these tools/services. WebPagetest tells us that our page is very slow – but dynaTrace on my local machine does not. What can be the problem here? What’s the difference? I took a look at their page on my own laptop – running WinXP and IE8. I saw a small JavaScript performance hotspot but nothing major. Then it occurred to me that WebPagetest is probably using a different browser which made me notice a feature of IE that I haven’t yet explore... (more)

Application Performance & Architectural Problems You Can Find in an Hour

When we get engaged with prospects that are interested in our performance management solution we walk them through a Proof of Concept. We let them install dynaTrace on their own prior to the actual POC. During the POC we ask them to exercise typical use cases on their application that show performance problems. We walk them through the different analysis options and add the findings to a final POC Presentation. In this blog I want to share some screenshots and findings of a typical Proof of Concept recently done in a heterogeneous .NET/Java Environment. Out-of-the-Box Result Pre... (more)
