Cloud interview question: In AWS, when you create a new subnet inside a VPC, is it public or private by default? and why? #cloud #aws

USA, India, and Nigeria are the top countries engaging with my posts. Looks like these countries dominate tech conversations on X. What about your analytics? 🌍

Conversation between HR and the CEO: HR: We need to increase staff salaries. If we don’t, they might leave and we’ll lose talent. CEO: But what if we don’t… and they stay? Then we win.

Cloud engineers, I need help! I have several public subnets that receive traffic from the internet. I want one subnet to stop receiving internet traffic, without converting it to a private subnet. What would you change? #AWS #CloudComputing #DevOps

Unpopular opinion If you really master Terraform, you don’t need Terragrunt or Terraform Workspaces to manage multi-environments. A well designed module structure and proper state separation are enough. #terraform #IAC

A recruiter calls you about a job. They need someone with strong Ansible and Golang experience. You tell them you’re not familiar with those tools. They ask you to update your resume and add them anyway. Would you do it, or refuse? #Devops

Kubernetes Upgrade Tip 6/10 Always prepare a recovery plan before upgrading. Kubernetes does not support downgrades. If something goes wrong, you can’t simply roll back the version. Plan your alternatives: - Restore the cluster from an etcd backup - Recreate the cluster
