Certification name change! ⚠️ AWS is officially renaming the SysOps Administrator – Associate to the CloudOps Engineer – Associate certification. The new SOA-C03 exam reflects how cloud operations are evolving, with more focus on: → Containers → Multi-account, multi-Region architectures → Automation, monitoring, and infrastructure as code Key dates to know: 📅 Registration opens: September 9, 2025 🛑 Last date to take SOA-C02: September 29, 2025 If you already hold the SysOps cert, it's still valid until expiry, but going forward, AWS will officially recognize the newer version under the CloudOps title. For anyone in DevOps, SRE, or cloud support roles, this update is a strong signal of where AWS operations are headed 👀 💬 What do you think of this shift from SysOps to CloudOps?

Cloud / DevOps Engineer tech stack: Junior vs Mid vs Senior (and what you can expect during interviews) How your Cloud & DevOps tools evolve through experience.. ↳ Entry-Level (0 - 2 years) • Linux & Shell Scripting • Docker & K8s basics • Basic Git workflows • Foundational DevOps concepts (CI/CD | Virtualization/ Containerization etc) • Troubleshooting skills (how can you fix a broken pipeline) • Jenkins / GitLab CI basics • AWS /GCP/ Azure core services ↳ Mid-level Cloud/DevOps Engineer (3-6 yrs): • Kubernetes for orchestration • Terraform for infrastructure • Ansible/Chef for configuration (in my previous life) • Logging Stack (Datadog/ELK) • Monitoring Stack (Datadpg/Prometheus/Grafana) • Python/Go automation (end-to-end workflow) • AWS/GCP/Azure advanced services ↳ Senior Cloud/DevOps Engineer (7-10 yrs): **Same tools but with architectural focus.. • Infrastructure for scalability • Security by design • DevSecOps Implementation strategies • Cloud Migrations ( understanding) • Service mesh Implementation & Management • Cost optimization patterns • Cross-cloud solutions • Platform engineering The main takeaway.. Although preparation with in-demand tools is necessary, understanding system design patterns is more crucial than knowing every tool. • • • What does your DevOps toolkit look like? 🤔 🔔 Follow me(Vishakha Sadhwani) for more Cloud & DevOps content ♻️ Share so others can learn as well

DevOps Skills ≠ DevOps Expertise What DevOps expertise is: - Achieving 99.99% deployment success rate - Optimizing CI/CD pipeline execution by 2x - Cutting Docker image size by 40% - Reducing build time to < 2 mins - Reducing rollback time by 70% so on... DevOps job is: 20% → building stuff 80% → optimization There are too stop at the build phase. High value, High pay is on the other side. Learning CI/CD pipelines, tool integration, etc. is just part of DevOps skills. ⸻ 👉 Follow Chigozie O. #StackedByChigozie for insights on DevOps, Cloud Engineering, Certifications, and hands-on learning experiences — from certifications to Kubernetes, bringing you real-world Cloud Engineering.

📁 Terraform Directory Structure – The Right Way! 💡 Are you managing your Terraform projects correctly? A well-structured Terraform directory ensures scalability, reusability, and efficient infrastructure management. Let’s dive deep into best practices! 🏗️ 1️⃣ Environments – Separate Configs for Dev, Staging & Prod Managing multiple environments? Here’s how to structure them: 📂 Development/ 📂 Staging/ 📂 Production/ Each contains: ✅ main.tf – Defines cloud resources. ✅ variables.tf – Declares variables without values. ✅ outputs.tf – Stores Terraform outputs for dependencies. ✅ terraform.tfvars – Provides values for variables. 🔹 Why? Isolates Dev, Staging, and Production setups. Avoids accidental production changes. Makes configurations modular & reusable. 2️⃣ Modules – Reusable Infrastructure Components Instead of repeating code, Terraform Modules help reuse configurations. 📌 VPC Module – Handles Virtual Private Cloud creation. 📌 EC2 Module – Manages EC2 instances efficiently. 🔹 Why? 🚀 Eliminates duplicate code – Define once, use everywhere! 🔄 Ensures consistency across environments. ⚙️ Faster deployment – Just call the module! 3️⃣ Scripts – Automate Terraform Workflows Automation is key in DevOps & IaC. These scripts help: ⚙️ init.sh – Initializes Terraform. 🛑 teardown.sh – Destroys infrastructure to save costs. 🔹 Why? Saves time by automating Terraform operations. Reduces manual errors while setting up infrastructure. 4️⃣ Core Terraform Files – The Brains of Your Infrastructure These files are the foundation of your Terraform project: ✅ provider.tf – Specifies the cloud provider (AWS, Azure, GCP). ✅ backend.tf – Defines state management (e.g., AWS S3, Terraform Cloud). 🔹 Why? Keeps Terraform state secure instead of local files. Prevents conflicts in team environments. 🔍 Why This Directory Structure Matters? ✅ Organized, modular, and scalable Terraform projects. ✅ Prevents accidental changes in production. ✅ Reusable infrastructure with Terraform Modules. ✅ Automated setup & cleanup with scripts. 💬 How do you structure your Terraform projects? Let’s discuss in the comments! 👇 📌 Follow for more DevOps insights! 🚀 #Terraform #DevOps #CloudComputing #InfrastructureAsCode #AWS #Azure #GCP #HashiCorp #Automation #CloudEngineering #TerraformBestPractices
