As an Associate Cloud Engineer at BlueCloud Inc, I've worked hands-on with AWS CloudFormation to implement efficient IaC practices. My role involved creating infrastructure templates for our ongoing projects and maintaining these templates for efficient scaling and quick bug-fixing.
One challenging project was the migration of a legacy application to AWS, where we re-architected the entire infrastructure leveraging AWS CloudFormation. The application was a multi-tiered web application with several interconnected components. I developed a CloudFormation script to automate the provision of all the necessary resources, utilizing services such as VPC, EC2, RDS, and S3.
The adoption of AWS CloudFormation allowed us to ensure consistent and repeatable infrastructure deployments. It also significantly reduced the time-to-market in new environments and the chances of human error during setup. The infrastructure code was written in YAML, and I implemented nested stacks for better manageability of the CloudFormation templates.
