DevOps Roadmap: Master 8 Key Pillars

The DevOps Roadmap: From Linux to CI/CD Feeling overwhelmed by the sheer number of tools in the DevOps ecosystem? You aren’t alone. The "DevOps Galaxy" is vast, but it becomes much easier to navigate when you view it as a progression of layers. Whether you are an aspiring engineer or a veteran leader, mastering these 8 pillars is the key to building resilient, scalable systems: 1. Linux Foundations: It all starts with the OS. Terminal proficiency and Bash scripting are non-negotiable. 2. Networking: Understanding how data moves (HTTP/S, SSH, TLS) is the backbone of connectivity. 3. Cloud Services: Knowing your way around AWS, Azure, or GCP is standard operating procedure. 4. Security: Shifting security "left" means focusing on encryption and authentication from day one. 5. Containers & Orchestration: Docker and Kubernetes are the engines of modern application delivery. 6. Infrastructure as Code (IaC): Treat your infra like software. Tools like Terraform and Ansible are game-changers. 7. Observability: You can’t fix what you can’t see. Monitoring and logging turn "guessing" into "knowing." 8. CI/CD: The finish line—automating the path from code to production. The takeaway? Don't try to learn every tool at once. Pick one tool from each layer, master the concept behind it, and the rest will fall into place. Which of these layers are you focusing on mastering in 2026?

🚀 DevOps Roadmap: From Linux to CI/CD Feeling overwhelmed by the endless tools in the DevOps world? You’re not alone. The ecosystem is huge, but it becomes much simpler when you break it down into layers. Whether you’re just starting out or already experienced, mastering these 8 core pillars is key to building scalable and reliable systems: 1️⃣ Linux Basics – Everything starts here. Strong command-line skills and Bash scripting are essential. 2️⃣ Networking – Know how systems communicate (HTTP/S, SSH, TLS). 3️⃣ Cloud Platforms – Get comfortable with AWS, Azure, or GCP. 4️⃣ Security – Think “shift left”—focus on security from day one. 5️⃣ Containers & Orchestration – Docker and Kubernetes power modern apps. 6️⃣ Infrastructure as Code (IaC) – Manage infra like code using tools like Terraform and Ansible. 7️⃣ Observability – Monitoring and logging help you understand and fix systems faster. 8️⃣ CI/CD – Automate everything from code to production. 💡 Key takeaway: Don’t try to learn everything at once. Focus on one tool per layer, understand the concept deeply, and build step by step. #DevOps #CloudComputing #SoftwareEngineering #TechCareer #Kubernetes #AWS #ContinuousLearning #Linux #SRE #CICD

Strengthening My Kubernetes Fundamentals 🚀 Recently, I revisited Kubernetes core concepts — specifically diving deeper into how Pods and Deployments actually function in real-world scenarios. What I love about Kubernetes is how it simplifies the entire container orchestration process — handling deployment, scaling, networking, and self-healing automatically. Creating a Pod is simple enough, but the real power lies in Deployments — they manage replicas, roll out updates smoothly, and handle failures without manual intervention. Understanding how Namespaces, Pods, and Deployments work together is truly essential for anyone stepping into Cloud-Native, DevOps, or SRE roles. Sharing this as part of my learning journey — if it helps even one person build a stronger Kubernetes foundation, that's enough for me. Let's keep learning and growing together! #Kubernetes #DevOps #CloudNative #Containers #LearningInPublic #TechLearning #CloudEngineer #SystemAdministration #OpenSource #CareerGrowth #TechJobs #AWS #Azure #GCP #90DaysOfDevOps #CloudComputing #Linux #Kubernetes #DevOps #CloudNative #Containers #LearningInPublic Aman Gupta Ashish Kumar #90DaysOfDevOps #CloudComputing #Linux #DevOpsEngineer #SRE #ContainerOrchestration #K8s #Microservices #Docker #Infrastructure #BackendDevelopment #SoftwareEngineering #TechCommunity #WomenInTech #LearningEveryday #Students #Graduates2025

🚀 Kubernetes Troubleshooting – Must-Know Commands In real-world DevOps, knowing Kubernetes concepts is good… but knowing the right commands during issues is what truly matters. Here are some essential Kubernetes commands I use for troubleshooting 👇 🔍 Pod Level Debugging ✔️ kubectl get pods -o wide ✔️ kubectl describe pod <pod-name> ✔️ kubectl logs <pod-name> ✔️ kubectl exec -it <pod-name> -- /bin/bash 🔍 Service & Networking Issues ✔️ kubectl get svc ✔️ kubectl describe svc <service-name> ✔️ kubectl get endpoints ✔️ kubectl port-forward <pod/service> 🔍 Cluster & Node Issues ✔️ kubectl get nodes ✔️ kubectl describe node <node-name> ✔️ kubectl top nodes ✔️ kubectl top pods 🔍 Namespace & Events Check ✔️ kubectl get all -n <namespace> ✔️ kubectl get events --sort-by=.metadata.creationTimestamp 🔍 Advanced Debugging ✔️ kubectl get pods -o yaml ✔️ kubectl describe deployment <name> ✔️ kubectl rollout status deployment <name> ✔️ kubectl rollout restart deployment <name> 💡 Pro Tip: When debugging, always follow this flow: 👉 Pod → Service → Network → Node → Logs 📈 These commands have helped me quickly identify issues like: - CrashLoopBackOff - ImagePullBackOff - Service not reachable - DNS failures #Kubernetes #DevOps #Troubleshooting #Cloud #AWS #SRE #Linux #TechTips

DevOps looks glamorous… until it doesn’t. At first, everything feels exciting: ✨ AWS dashboards ✨ Automation scripts ✨ CI/CD pipelines ✨ Beautiful monitoring tools You feel like you're building the future. Then reality hits… You're SSH-ing into servers at 2 AM. You're digging through `/var/log` trying to find what broke. You're writing quick Bash scripts to fix production issues. You're debugging things that worked perfectly… yesterday. That’s when you realize: DevOps isn’t just about tools. It’s about problem solving, patience, and learning Linux deeply. My biggest DevOps lesson: You might ignore Bash & Linux at first… But eventually — the terminal finds you. And when it does, that's when you truly start growing as a DevOps engineer. #DevOps #Linux #Cloud #Automation #SRE #DevOpsEngineer 🚀

Today I faced an Interview at Ensono for AWS DevOps Engineer 1. Self intro 2. How you handle the state management in your environment? 3. where do we use the Terraform workspaces? What is the exact use of it? 4. you have a workspace for dev QA product. so unfortunately, you've deleted the prod workspace, so what will happen now? 5. you have stored everything in S3 back-end, So only workspace is deleted. So can we bring that state once again in a new workspace? Will it work? 6. what happens if a provider is getting upgraded? for example, you are in an AWS 7.5 provider, and that needs to be updated to 7.6. It's a major version. So how do you plan for this? 7. you have a S3 bucket, so that needs to be provided access. So you can do it in two ways. One is from IAM perspective, you can provide a IAM policy. 8. you have a Linux server, this has been deployed via Terraform like a month ago with the data volume through Terraform itself. So currently it is sizing with 500 GB. the application team has started using it and they wanted to extend the block system to 750 GB. so now you are going into the your own workspace in Terraform and reviewing the code and you are changing the additional disk volume size GB from 500 to 750 GB. Okay, if you run a Terraform plan and apply, what will happen here? 9. Diffrence between Private VPC and Public VPC? 10. you have a RDS database. So there is a concept called Multi-AZ. and there is a concept called Read Replicas. So what is the difference between these two? 11. for example, there is an EC2 maintenance that's been called out for after two weeks, so there is a notification has been published on the AWS dashboard for a particular EC2 instance. So now that fault has a critical change window, so you don't want that set last deadline as per the notification, but you don't want to do that. So is there a way to postpone this? 12. what are the cost optimization initiatives you have taken in your current environment? 13. Explain where the Jenkins have been used in your environment? #devops #devopsengineer #aws #awsdevops #terraform #jenkins #linux
