Sample Response: Associate

As a DevOps Engineer at Tech Corp, I have had the opportunity to work extensively with Microsoft Azure and specifically, Azure Resource Manager (ARM) templates. Infrastructure as Code (IaC) is a key principle we follow and ARM templates have been instrumental in achieving this.

One specific project that stands out was a transition phase where we migrated a monolithic application to Microsoft Azure. Our primary strategy involved leveraging ARM templates to codify and manage the infrastructure, thus creating a thorough template library for repeated, reliable deployments.

We used an ARM template to automate the setup of an Azure App Service that helped us host and manage web applications. This resulted in a shift from manual configuration to automated deployments which significantly improved the speed and consistency of our infrastructure deployments.

Through this experience, I’ve learned the efficiency and reliability that IaC provides, and I am driven to continue leveraging such technologies for streamlined and efficient operations.
