FAQ

All courses are hosted on Udemy. When you click "Enroll" on any course page on stacksimplify.com, you'll be taken to Udemy where you can purchase and access the course. Udemy handles payments, video streaming, certificates, and the Q&A system.

I currently have 21 published courses covering Terraform (7 courses), Kubernetes (5 courses), AWS Services (5 courses), DevOps & Docker (2 courses), and GCP + Spring Boot (2 courses). Browse them all on the Courses page.

It depends on your background:

• New to containers? Start with Docker in a Weekend
• Want Kubernetes? Choose based on cloud: AWS EKS, Azure AKS, or GCP GKE
• Want Terraform? Start with Terraform Associate on AWS for certification, or Terraform on AWS SRE for production skills
• Want the full DevOps stack? Try the Ultimate DevOps Project on AWS

Yes! The AWS VPC Transit Gateway course is completely free. It covers AWS networking fundamentals and is a great way to experience my teaching style before enrolling in a paid course.

The best way to get the latest coupons is to:

1. Check each course detail page — active coupons are displayed prominently
2. Subscribe to the newsletter — I send exclusive coupons to subscribers
3. Watch for the promotional banner on the website — it always shows the current best offer

Coupon codes expire at the end of each month. If a code isn't working:

• Check if the coupon has expired (look for the current month's code on the course page)
• Make sure you're on the correct Udemy course link (some coupons are course-specific)
• Try clearing your browser cookies and accessing the link again
• If it still doesn't work, email me and I'll send you an updated link

Refunds are handled by Udemy, not by me directly. Udemy offers a 30-day money-back guarantee on all course purchases. You can request a refund through your Udemy account within 30 days of purchase.

Yes! Every course has a dedicated public GitHub repository with complete code, Terraform manifests, Kubernetes YAML files, and step-by-step documentation. You can fork the repo and follow along at your own pace. Find all repositories at github.com/stacksimplify.

Two ways:

• GitHub Issues: Open an issue on the course's GitHub repository — this is preferred for code bugs or documentation errors
• Udemy Q&A: Post in the course Q&A section — best for video content issues or conceptual questions

I actively monitor both channels and appreciate every report — it helps me keep courses up to date for everyone.

docs.stacksimplify.com is the companion documentation site for my Kubernetes courses (AWS EKS, Azure AKS, GCP GKE) and the GCP Associate Cloud Engineer course. It contains 300+ step-by-step guides that complement the video content.

terraformguru.com is a dedicated Terraform documentation site with step-by-step guides for all 7 Terraform courses — covering AWS, Azure, GCP, EKS, and certification preparation. It's the go-to reference while working through Terraform courses.

Yes. Udemy provides a certificate of completion once you've watched all the lectures in a course. You can download it from your Udemy dashboard and share it on LinkedIn. Note: this is a Udemy certificate, not an official cloud certification.

Several courses are specifically designed for certification prep:

• HashiCorp Terraform Associate (AWS) — 50 practical demos
• HashiCorp Terraform Associate (Azure) — 70 demos
• GCP Associate Cloud Engineer — 150 demos

These courses cover all exam objectives with hands-on practice. Many students have passed their certifications using these courses.

Lifetime access. Once you purchase a course on Udemy, you have access forever — including all future updates. I regularly update courses when cloud providers release new features or when tools get major version bumps.

Yes, most demos create real cloud resources that will incur costs. However, I always:

• Use the most cost-effective instance types and configurations
• Include cleanup instructions at the end of every demo (terraform destroy, kubectl delete, etc.)
• Highlight which resources cost money and approximate hourly rates

Tip: Always run cleanup commands immediately after completing each demo to minimize costs. Most demos cost less than $1-2 if you clean up promptly.

Prerequisites vary by course, but generally:

• Docker course: Basic Linux command line knowledge
• Kubernetes courses: Docker fundamentals (take Docker course first)
• Terraform courses: Basic understanding of the target cloud (AWS/Azure/GCP)
• Certification courses: Some hands-on cloud experience recommended

Each course page lists specific prerequisites. When in doubt, start with Docker in a Weekend.
