Hi Sir, Thanks for making the things easier. I have a doubt from where you got that result.json and Helppowershell file before updating the cluster? Thanks!

[@cloudquicklabs]

Thank you for watching my videos. Please check the video at 5:23 minute you see that I am executing a powershell script which gives the output and stored in results.json.

Hi sir what is the difference between EMR Cluster vs EKS Cluster?

[@cloudquicklabs]

Thank you for watching my videos. EMR : is Elastic Map Reduce which is managed big data processing and analytics service. EKS: is Elastic Kubernetes Service which is basically managed Kubernetes (container orchestration) Service. Both are different.

@@cloudquicklabs Okay, hum yahan kah sakte hain ki EMR jo hai, wo Spark aur PySpark ke jobs run karta hai aur EKS jo hai, wo Python ke jobs run karta hai.
