Jon mentions Observability of your applications and infrastructure.

Al mentions a Youtube channel that has interviews with DevOps/SRE professionals.

Al asks about tracing, and Stu explains why tracing and telemetry is becoming more important now that applications are being split into containers ("Microservices architecture").

Al asks about Jenkins, Stu mentions about the popularity of Jenkins. Jerry mentions how Jenkins being central to your deployments can be a problem, given how much access it often has to your estate.

Stu also mentions about the Jenkins plugin architecture, and how that there is almost always a plugin available for Jenkins to achieve a task, but it can make managing Jenkins a problem (dependencies can become an issue). He also mentions his preference on how to use Jenkins.

Stu mentions ArgoCD for managing Kubernetes deployments.

Jerry mentions the Groovy language, which is used to configure Jenkins jobs and pipelines.
