Terraform Cert Guide Chapter 11: Terraform Glossary in Plain English

Chapter 11 is the glossary chapter. In most books, glossaries sit at the back collecting dust. But honestly, if you’re studying for the Terraform certification, this is the chapter you’ll keep coming back to.

Data Engineering With AWS Chapter 14: Wrapping Up the Learning Journey

This is post 20 in my Data Engineering with AWS retelling series.

We made it. Thirteen chapters of pipelines, transforms, orchestration, security, querying, visualization, and machine learning. Chapter 14 is the final chapter. It does not introduce a new AWS service. Instead, it zooms out. Way out. It looks at how data engineering works in the real world, shows you case studies from Spotify and Netflix, and points you toward where the field is heading next.

Terraform Cert Guide Chapter 10: Terraform Cloud and Enterprise Explained

But the moment your team grows beyond a couple of people, things get messy fast. Chapter 10 introduces the solutions HashiCorp built for exactly that problem: Terraform Cloud and Terraform Enterprise.

Golang DSA Chapter 9 Part 2: Sparse Matrices and Real-World Uses

Welcome back. In Part 1 we covered graph fundamentals, social networks, and map layouts. Now Kommadi finishes Chapter 9 with two more practical topics: knowledge graphs and sparse matrix representation. Both build on the graph foundation from Part 1, but they’re different enough to deserve their own discussion.
