The brief history of IaC

Covered the history of infrastructure-as-code in this video as a preparation for a webinar where I'll be hosting Adam Jacob - the creator of Chef.

Free Advanced DevOps Video Series – For Developers Transitioning to DevOps

Hey folks,


If you're a developer, sysadmin, or cloud enthusiast looking to shift into DevOps, here’s something useful.

I’ve compiled a few free, advanced-level DevOps playlists that are now available on YouTube. These cover real-world tools and go beyond beginner tutorials — useful for anyone wanting to build depth or prep for a role in CI/CD, automation, or cloud infrastructure.

# 🎓 What’s Covered?

Ansible Full Course (15+ Hours / 9 Sessions) Covers YAML, playbooks, roles, inventory, real-world automation. ▶️ [https://www.youtube.com/watch?v=MJ9yJoPmypc&list=PLO9ci1OliMiPHEbSjkSphCHAdqco5rt8K](https://www.youtube.com/watch?v=MJ9yJoPmypc&list=PLO9ci1OliMiPHEbSjkSphCHAdqco5rt8K)
Jenkins CI/CD Complete Course (17+ Hours / 10 Videos) Deep dive into Jenkins pipelines, jobs, integration with Git, Docker, etc. ▶️ https://www.youtube.com/watch?v=ZQBb751E2sg&list=PLO9ci1OliMiNorLuMdVfthBO4hII9uTjz
Python for DevOps Engineers (6+ Hours) Scripting, subprocesses, automation, API calls, and real use cases. ▶️ [https://www.youtube.com/watch?v=ZQBb751E2sg&list=PLO9ci1OliMiNorLuMdVfthBO4hII9uTjz](https://www.youtube.com/watch?v=ZQBb751E2sg&list=PLO9ci1OliMiNorLuMdVfthBO4hII9uTjz)
Shell Scripting for DevOps (6+ Hours) Covers bash, conditions, loops, automation tasks — perfect for Linux-based workflows. ▶️ https://www.youtube.com/watch?v=COR8xdfX3tU&list=PLO9ci1OliMiNUicQCjqA77bEDHDGF\_usI

🛠 All videos are detailed, hands-on, and go beyond theory. You’ll find production-style implementations and use cases — not just hello-world scripts.

🔖 Bookmark this if you're planning to move from development to DevOps in the coming months. No fluff. Just structured content for real growth.

More topics like Docker, Kubernetes, Terraform, and AWS pipelines will be added soon.

Hope it helps someone on their DevOps journey. 🙌

Learn Azure Bicep for Beginners – Build Your First Azure Infrastructure as Code

Hey everyone 👋 If you are interested in learning Azure Bicep, I have just published a beginner-friendly YouTube tutorial that walks you through Microsoft’s native Infrastructure as Code (IaC) language, designed to make deploying Azure resources easier, cleaner, and more consistent https://youtu.be/hksEWvk9p-0?si=FAXpFbxvut-gNAkZ

Terraform AWS Infrastructure Framework (Multi-Env, Name-Based, Scales by Config)

🚀 Excited to share my latest open-source project: a Terraform framework for AWS focused on multi-environment infrastructure management.

After building and refining patterns across multiple environments, I open-sourced a framework that helps teams keep deployments consistent across dev / qe / prod.

The problem:
- Managing AWS infra across dev / qe / prod usually leads to:
- Configuration drift between environments
- Hardcoded resource IDs everywhere
- Repetitive boilerplate when adding “one more” resource
- Complex dependency management across modules

The solution:
A workspace-based framework with automation:

- ✅ Automatic resource linking — reference resources by name, not IDs. The framework resolves and injects IDs automatically across modules.
- ✅ DRY architecture — one codebase for dev / qe / prod using Terraform workspaces.
- ✅ Scale by configuration, not code — create unlimited resources WITHOUT re-calling modules. Just add entries in a .tfvars file using plain-English names (e.g., “prod_vpc”, “private_subnet_az1”, “eks_cluster_sg”).

What’s included:
- VPC networking (multi-AZ, public/private subnets)
- Internet gateway, NAT gateway, route tables, EIPs
- Security groups + SG-to-SG references
- VPC endpoints (Gateway & Interface)
- EKS cluster + managed node groups

Real example:
# terraform.tfvars (add more entries, no new module blocks)
eks_clusters = {
prod = {
my_cluster = {
cluster_version = "1.34"
vpc_name = "prod_vpc" # name, not ID
subnet_name = ["pri_sub1", "pri_sub2"] # names, not IDs
sg_name = ["eks_cluster_sg"] # name, not ID
}
}
}
# Framework injects vpc_id, subnet_ids, sg_ids automatically

GitHub:

Looking for:
- Feedback from the community
- Contributors interested in IaC patterns
- Teams standardizing AWS deployments

Question:
What are your biggest challenges with multi-environment Terraform? How do you handle cross-module references today?
