Observability is rather a data analytics problem as it needs to give humans answers to DevOps, SRE and Business questions.To learn more beyond what was discussed in this podcast listen in to OpenObservability Talks, stay up to date on OpenTelemetry or follow Dotan at @horovitsShow LinksDotan Horovits on Linkedinhttps://www.linkedin.com/in/horovits/Open Observability Talkshttps://openobservability.io/Open Telemetry Projecthttps://opentelemetry.io/Dotan Horovits on Twitterhttps://twitter.com/horovits

Who said that automation and data-driven decisions is only for DevOps or SREs? Scalability challenges or quality constraints are just as important to digital marketers like Nina Tollefson, Art Director at Dynatrace.The pandemic caused many events to transform to a fully virtual. That was also true for Dynatrace’s flagship annual global user conference Perform in February 2021. To successfully transform and deliver a flawless experience for Perform attendees, Nina had to embrace automation in her field of work. Just as DevOps engineers Nina updated her tool chain. Figma was a new digital marketing platform of choice to automate, improve collaboration, become more efficient and scale her digital marketing work to support Perform. Today she can cash in on the automation investment she made last year as Perform 2022 is about to start. Thanks to data-driven digital marketing automation it looks like another amazing experience for our global Dynatrace user base. Thanks, Nina, for sharing your story and allowing us

Encore Presentation - we'll be back in early 2022, until then, here is one of our favorite recent episodes:To k8s or not – that should be the first question to answer before considering k8s. Granted – in many cases k8s is going to be the right choice but don’t just default to k8s because its hip or cool.

The rise of smart phones clearly created a new demand for “instant gratification” when it comes to interacting with online services through web sites or apps. To ensure services are available at any point in time without any interruption or delay it requires performance engineers to automate performance and scalability engineering into the development processes.In this episode we invited Mike Kobush, Performance Engineer at NAIC, to hear how he found his way in quality engineering and later on got hooked on performance. He walks us through current performance challenges as his organization is moving to the cloud. Mike also discusses why he is embracing automation as it makes him more desirable as an employee.
