While speeding up development processes and reducing complexity does make the lives of Kubernetes operators easier, the inherent abstraction and automation can lead to new types of errors that are difficult to find, troubleshoot, and prevent. Monitoring makes sense of observability data. What does observability mean for Kubernetes?

And when discussing the two types of data, we’re actually talking about what is called real-user monitoring , or RUM for short. For example, the data is pretty slow to update, refreshing every 28 days, meaning it is not the same as real-time monitoring. But it comes with caveats. Does Lighthouse Use RUM Data, Too?

Kubernetes (aka K8s) is an open-source platform used to run and manage containerized applications and services on clusters of physical or virtual machines across on-premises, public, private, and hybrid clouds. This virtualization makes it possible to efficiently deploy and securely run a container independently of the hosting infrastructure.
