Content These three IAM security misconfiguration scenarios are rather common. Discover how they can be exploited, but also, how easy it is to detect and correct them. Identity and access management (IAM) misconfigurations are one of the most common concerns in cloud security.

Our Journey Into Cutting Kubernetes Costs by 40%

As companies start their Kubernetes and cloud-native journey, cloud infrastructures and services grow at a rapid pace. This happens all too often as organizations shift left without thorough controls, which can lead to overallocating and overspending on their Kubernetes environments.

Kubernetes Services: ClusterIP, Nodeport and LoadBalancer

Pods are ephemeral. And they are meant to be. They can be seamlessly destroyed and replaced if using a Deployment. Or they can be scaled at some point when using Horizontal Pod Autoscaling (HPA).

A day in the life of a Customer Support Detective

I open my laptop and look over my cases while I slurp down my first cup of coffee. Most of my backlog is waiting on customer updates, or bug fixes. Two of my cases have been marked for closure. Not a bad start for a Monday! A pod CrashLoopBackoff issue was resolved by bumping up memory requests, and the missing metrics issue was solved after applying some Prometheus annotations to the customer’s nginx pods. I notate and close both cases. No sooner do I hear the beep of the badge scanner.
