Big Techday the Thirteenth - anything but ordinary
Coming soon: TNG presents the annual Big Techday. The science and technology conference, with a focus on IT, will stream live online on Friday May 8th, 2020. We are excited to present talks on subjects such as artificial intelligence, cloud computing, programming languages as well as on trends and topics far removed from the regular everyday of IT consulting, e.g. the interaction of science and philosophy. The Big Techday offers an opportunity to think outside the box and gain insights into many varied and highly interesting fields. This year our speakers include, Pawel Kmiec "The Story of Glomar Explorer in a Giant LEGO Version", Joseph Viehauser and Maximilian Bode "Creating a Data-Driven, Cloud-Native Ecosystem at the BMW Group", as well as many more. Further information including the complete timetable and abstracts of the talks can be found here. We are already looking forward to a uniquely interesting and entertaining Big Techday.
TNG goes virtual
Sometimes, we have to make a virtue of necessity. In view of the spreading SARS-CoV-2 virus TNG started an experiment last Friday, a “Virtual Techday.” This consisted of virtual workshops, presentations and even a virtual “Weekly half-hour,” an informative in-house event hosted by the TNG partners. The Weekly Half-hour had previously been streamed, in addition to the actual presentation. However this was the first time as a purely virtual video conference. Up to 230 colleagues attended simultaneously, applauded via emoticons, and posted comments in the chat.
The feedback on the virtual Techday experiment was extremely positive. However, we are all looking forward to meeting again in person.
Remedy for Performance Issues
The colleagues will talk about this topic at the Virtual Big Techday on May 8th, 2020.
Black Friday: every year this top-selling day poses a unique challenge to our rapidly growing customer in the online retail industry. The webshop must operate reliably under an unprecedented load. Despite a hardware upgrade, in 2019 there were already short service disruptions observed at peak times prior to Black Friday. Trouble was clearly imminent.
We identified and resolved multiple performance bottlenecks. The configuration of the application was then optimised in an iterative fashion. This was done using a JMeter test plan with request distribution modelled on customer behaviour. Executing it from the cloud directly against the production servers enabled us to test different load scenarios. At the same time, technical and organisational measures were taken to ensure that customer shopping remained undisturbed. Elastic Stack, Prometheus & Grafana served as the main tools to identify and analyse backend metrics.
Ultimately the improvements yielded the desired result. The throughput doubled, but the system withstood this crucial phase without any issues. The new monitoring processes allows future performance problems to be detected, understood, and rapidly solved.
