CI/CD, or Continuous Integration and Continuous Deployment, is a fundamental practice in DevOps that emphasizes automation in the software development and deployment processes. Continuous Integration focuses on merging code changes into a shared repository as frequently as possible, allowing for early detection of issues. Continuous Deployment automates the release of code changes to production, ensuring that new features and fixes reach users quickly and reliably. Understanding these concepts is crucial for a Junior DevOps Engineer at Peraton, as they form the backbone of effective software delivery.

To troubleshoot a failed deployment in Jenkins, start by reviewing the build logs for error messages that provide insight into what went wrong. Check for issues with the CI/CD pipeline, such as configuration errors or problems with environment setup. It might also be helpful to run the pipeline steps manually to isolate the problem. Understanding how to analyze logs and systematically address errors is key for a Junior DevOps Engineer at Peraton.

Infrastructure as Code (IaC) refers to the practice of managing and provisioning computing infrastructure through code instead of manual processes. In the context of DevOps, IaC enables teams to automate infrastructure management, ensuring consistency, repeatability, and rapid deployment. As a Junior DevOps Engineer, familiarity with IaC principles and tools like CloudFormation will equip you to effectively manage cloud resources in a scalable manner at Peraton.
