  • What is the role of QoS for Pods?
    There are tools CastAI (https://cast.ai/) and KubeCost (https://www.kubecost.com/) which helps you get these values. I haven't tried it personally, but they are promising.

Generally take the p95 value for requests and 1.5-2x... Source: about 3 years ago
  • Kubernetes Cost Monitoring
    Not sire if this helps but someone just showed me this free tool that looks at cost for Kube https://cast.ai/. Source: about 3 years ago
  • Is k8s Kops preferable than eks?
    Curious about what about cast.ai sets it apart for you? I went with spot because it is owned by a big company and knew it wasn't going to disappear. I think cast was still in invite only mode, as well. Source: over 3 years ago
  • Scheduled spindown/up of clusters?
    I found that cast.ai seems to have this functionality but am wondering if there is a free option. Also pursuing gMaestro but they're not available on arm64 yet. Source: over 3 years ago
  • Reducing AWS costs?
    If you're using Kubernetes, CAST AI is the fastest way to significantly reduce your compute bill and keep it there. It manages compute capacity automatically and has dedicated support to get you started even faster. The best part - Kubernetes cost monitoring and security insights are free.
