When you keep a blog like this, you also keep the logs of important moments in your life, such as passing AWS certification exams. Time really flies! It is hard to believe almost three years have passed since my first Professional-level AWS certification.

Last week, I retook the AWS Certified DevOps Engineer - Professional exam to recertify for three more years and passed with a 943/1000 score. There were newer services in the exam content than the previous version, and online proctoring was also a different experience. Hence, in this post, I will share my experiences with you in case you also plan to take the AWS Certified DevOps Engineer - Professional exam soon.

As you start using AWS CloudFormation for bigger projects, your templates and stacks get larger. Therefore, managing them gets more difficult day by day. Then, at some point, you realize that you need a way to divide your templates into smaller ones to manage them more efficiently.

AWS CloudFormation provides two methods for this, cross-stack references and nested stacks. As you may guess, each technique has different use cases and strengths. Hence, in this post, let’s discuss some of the differences between cross-stack references and nested stacks.

AWS CodeBuild is the serverless build service of AWS, and until now, I covered various ways of using it in my previous posts. Today, I would like to talk about how to define and use environment variables in your build specification files or, in other words, buildspecs. In a build project, you can assign plain texts to your environment variables, read parameters from AWS Systems Manager Parameter Store, or retrieve secrets from AWS Secrets Manager. I will give examples to each.

Besides, you can also use AWS CodeBuild with AWS CodePipeline as a part of a CI/CD pipeline. We discuss how to do this in my AWS CodePipeline Step by Step course. Therefore, I will also give an example of exporting an environment variable from a build to be able to use it in a later pipeline action.
