If I were starting on AWS today, I would do this as a beginner using the 12 Month Free Tier to stay within AWS Free Tier limits and avoid billing shocks. 1) 𝗞𝗻𝗼𝘄 𝗪𝗵𝗮𝘁’𝘀 𝗔𝗰𝘁𝘂𝗮𝗹𝗹𝘆 𝗙𝗿𝗲𝗲 12 month Free Tier includes: - 750 hours/month of t2.micro or t3.micro - 5 GB S3 storage - 750 hours of RDS db.t2.micro so on… 2) 𝗦𝗲𝘁 𝗮 𝗕𝗶𝗹𝗹𝗶𝗻𝗴 𝗔𝗹𝗮𝗿𝗺 𝗼𝗻 𝗗𝗮𝘆 1 - Go to Billing → Budgets → Create Budget - Set an alert at $1 or $5 to stay notified early 3) 𝗠𝗼𝗻𝗶𝘁𝗼𝗿 𝘄𝗶𝘁𝗵 𝗖𝗼𝘀𝘁 𝗘𝘅𝗽𝗹𝗼𝗿𝗲𝗿 - Use filters by service or region - Spot growing usage before it crosses Free Tier limits 4) 𝗧𝗮𝗴 𝗔𝗹𝗹 𝗥𝗲𝘀𝗼𝘂𝗿𝗰𝗲𝘀 Use tags like FreeTierTest or CleanupLater, makes cleanup easier and usage visible 5) 𝗖𝗹𝗲𝗮𝗻 𝗨𝗽 𝗔𝗰𝘁𝗶𝘃𝗲𝗹𝘆 Even stopped resources can be billed: - EC2 stopped = OK - EBS volumes = Charged until deleted - RDS = Charged for storage even if paused so on., 6) 𝗥𝗲𝘀𝘁𝗿𝗶𝗰𝘁 𝗪𝗵𝗮𝘁 𝗖𝗮𝗻 𝗕𝗲 𝗟𝗮𝘂𝗻𝗰𝗵𝗲𝗱 - Use IAM to allow only Free Tier services - Block things like NAT Gateway and large EC2 types If you're starting today, save this list. An hour setup can save you from a five figure mistake. 49K read my DevOps and Cloud newsletter: techopsexamples.com/subscrib… What do we cover: DevOps, Cloud, Kubernetes, IaC, GitOps, MLOps 🔁 Consider a Repost if this is helpful

For the 100th time: Kubernetes is not an entry level job. It requires a deep understanding of container orchestration, architecture, complex system integrations, Linux, networking, security best practices, and the ability to troubleshoot and optimize distributed systems effectively. Expecting entry level engineers to run production grade clusters with 99.99% uptime is unreasonable. Hire seasoned pros and pair them with juniors, so expertise flows and learning grows. 48K read my DevOps and Cloud newsletter: techopsexamples.com/subscrib… What do we cover: DevOps, Cloud, Kubernetes, IaC, GitOps, MLOps 🔁 Consider a Repost if this is helpful

Kubernetes Port Forwarding Patterns 👇 You're inside a dev cluster, access to the network is restricted, and the service you just deployed is acting up. There’s no LoadBalancer, no ingress controller in place, and opening up a port is not an option because the network team is either slow or says no. This is where kubectl port-forward unblocks you. Here I've simplified for your easy understanding. 48K read my DevOps and Cloud newsletter: techopsexamples.com/subscrib… What do we cover: DevOps, Cloud, Containerization, IaC, GitOps, MLOps 🔁 Consider a Repost if this is helpful

Wall design for my office 👇 We Kubernetes folks get so caught up in logs and alerts that we forget the fastest fix is often a conversation. Someone’s seen it. Someone’s solved it. A 2 minute chat can save a 2 hour rabbit hole. Talk to humans. It’s underrated.

Official documentation is concise - a good guide to get you started. But actual problems in Kubernetes administration are vast 😅 This is well know. - Official paths might lead to dead ends. - Official guides won't cover every edge case. - Official commands don't always do the trick. - Official examples often don't match your setup. - Official docs might not keep up with fast changes. (Not in this particular order) - Use your creativity to find workarounds. - Use your failures as lessons for the future. - Use your team to brainstorm tricky problems. - Use your time to explore alternative solutions. - Use your experience to build your own playbook. 48K read my DevOps and Cloud newsletter: techopsexamples.com/subscrib… What do we cover: DevOps, Cloud, Kubernetes, IaC, GitOps, MLOps 🔁 Consider a Repost if this is helpful

DevOps Vs DevSecOps 👇 𝗗𝗲𝘃𝗢𝗽𝘀 focuses on collaboration and automation between development and operations. 𝗗𝗲𝘃𝗦𝗲𝗰𝗢𝗽𝘀 extends this approach to include security as a core consideration throughout the software development lifecycle. DevSecOps adds value by implementing a "𝘀𝗵𝗶𝗳𝘁-𝗹𝗲𝗳𝘁" approach, where security is integrated early in development, following a "𝗳𝗮𝗶𝗹-𝗳𝗮𝘀𝘁" philosophy to catch and address vulnerabilities quickly. 48K read my DevOps and Cloud newsletter: techopsexamples.com/subscrib… What do we cover: DevOps, Cloud, Kubernetes, IaC, GitOps, MLOps 🔁 Consider a Repost if this is helpful

Starting with Kubernetes is smooth - all the online courses live up to this. But managing multiple clusters quickly turns into a complex reality - you end up with this. 😅 That's ok, this is expected. No one is immune to this. - It takes time to deep dive. - It takes small steps when scaling up. - It takes perseverance to get it right. - It takes continuous learning to keep up. - It takes a team effort to manage complexities. (Not in this particular order) - Take advantage of your curiosity - Take advantage of LinkedIn to outreach - Take advantage of open-source resources - Take advantage of mentorship opportunities - Take advantage of industry webinars and talks 48K read my DevOps and Cloud newsletter: techopsexamples.com/subscrib… What do we cover: DevOps, Cloud, Kubernetes, IaC, GitOps, MLOps 🔁 Consider a repost if this is helpful.

You do not really learn AI Agents by reading threads or copying prompts. Production is different. Agents forget context, Tools return noisy results, Token limits get wasted, One bad retrieval changes the entire output. You learn it by debugging why an agent ignored instructions, or failed after 20 successful runs. Luckily PerfectScale Community created a hands on workshop. Learn how to handle AI Agents practically here: info.perfectscale.io/worksho… It is quite useful. 🔁 Consider a Repost if this is helpful
