Trades of a Performance Engineer in 2020!

Last week at AWS re:Invent we heard Werner Vogels, CTO at AWS, talk about how to build the applications of 2020! Listening to Werner’s talk, it became apparent to me, that this it also means that we have to “re:Think” how we go about Performance Engineering. Because of what I heard at re:Invent I almost wanted to title this blog “Performance Engineering is Dead!“,  but that wouldn’t reflect… read more

Auto-Mitigation with Dynatrace AI – or shall we call it Self-Healing?

After our AI-Driven DevOps webinar with Anil from Verizon Enterprise I got into a debate with my colleague Dave Anderson on how to call the auto mitigation approach we discussed during the webinar: Is it “auto mitigation”, “auto remediation” or shall we be bold and call it “self-healing”? Instead of getting caught up on terminology I thought to write this blog post and explain our thoughts and let… read more

Load Testing Redefined: A Guide from KPI Reporting to AI Supported Performance Engineering

The primary goal of Performance and Load Testing hasn’t changed a lot since I started working in this industry in 2001. What has changed are the application frameworks (from plain HTML via jQuery to Angular) and a shift from page-based to single page apps consuming backend REST APIs using JSON via HTTP(S). Having these services accessible via well-defined service contracts is a blessing for load testers, as we can easily… read more

DevOps in the Real World with Atlassian and Dynatrace

Atlassian is trying to redefine work, collaboration, and flow of work. One word that seems to sum it up nicely is DevOps as it embraces a different way of how we think about how we create value for our customers and our employer and how the work we create flows through our processes. As the DevOps activist that I am, I was very interested in hearing the stories from Stephan… read more

Atlassian Connect(-ing) DevOps Tools JIRA, xMatters and Dynatrace

Atlassian Connect brings together developers from around the world to build better connected tools in the Atlassian Ecosystem. Last week’s Atlassian Connect Week in Austin, Texas was Dynatrace’s first attendance of this 5 day Hackathon-style event. While we came prepared to build new and tighter integrations between Dynatrace, JIRA Cloud, JIRA Service Desk and HipChat we left this event with additional integrations we built with our friends… read more

DevOps: Adoption Challenges from Around the World

DevOps is now a mandatory CIO initiative, and would be hard to dismiss it as a short-term trend. It is a proven competitive differentiator to help increase speed to market, increase operational efficiency, and lower costs, and a large majority of companies and industries are getting on board. To confirm my statements let’s look at the latest State of the DevOps Report which Puppet and DORA announced at… read more

Federal DevOps: Learning from Government

In June I was invited to present my view on DevOps at the ATARC – Federal DevOps Summit in Washington, DC.  Little did I know that my assumption of government agencies lagging in the adoption of the latest technologies and practices was WRONG.  And this was proven so many times throughout the day as representatives from government agencies took the stage and explained how their teams are fully… read more

What do Velocity San Jose, UFOs and hackathons have in common?

I recently attended Velocity, in San Jose, and live blogged my reactions, highlights and takeaways from the show here. However, one conversation I had while on “booth babe” duty was worth separating out from the rest. It was a conversation I had with Greg Stark, Sr. Software Engineer at Study.com. Greg tracked me down at Velocity, as he wanted to share their own Dynatrace Pipeline State… read more

Live from Velocity San Jose 2017

Velocity has transformed over the last couple of years – such as how organizations transformed their way of building, scaling and maintaining the software that powers their business. I remember the early days of Velocity where it was all about Web Performance Optimization, then it moved over to Web Scale, DevOps, Building Resilient Systems and now we arrived at this years theme which is: Building and maintaining complex… read more

Correlating JavaScript Errors with Slow CDN Performance

JavaScript Errors can happen for many different reasons: special behavior of certain browsers that weren’t tested; a real coding mistake that slipped through the delivery pipeline; poorly handled timeouts, and I am sure the list goes on. In this blog we discuss yet a different reason which was brought to my attention by Gerald Madlsperger, one of our long term Dynatrace AppMon super users: A CDN server… read more
