I am currently trying to migrate our legacy Jenkins freestyle jobs to a more robust Pipeline as Code structure using Jenkinsfile. Since we are moving towards a multi-cloud strategy involving AWS and Azure, I am looking for best practices on how to handle environment-specific configurations without hardcoding credentials. What is the most scalable way to manage this?

Definitely use the "Environment" directive in your Declarative Pipeline to map different credentials IDs based on the branch name.
Transitioning to a Jenkinsfile is a game-changer for version control. For multi-cloud setups, I highly recommend using Jenkins Shared Libraries to centralize your deployment logic. This avoids duplication across repositories. To handle environment variables across AWS and Azure securely, integrate Jenkins with a secrets manager like HashiCorp Vault or AWS Secrets Manager rather than relying solely on the internal credentials store. This ensures that your 'Build Once, Deploy Anywhere' principle remains intact while keeping your pipeline scripts clean and portable across different cloud providers.
Are you planning to use the Kubernetes plugin to dynamically scale your Jenkins agents on these cloud platforms to save on costs?
That is a great point, Michael. Using the Kubernetes plugin allows us to spin up ephemeral agents in EKS or AKS only when a build is triggered. This significantly reduces idle resource costs. We are currently configuring the pod templates in our shared library so that each stage in the Jenkinsfile can request a specific container image tailored for either AWS CLI or Azure CLI tasks.
I agree with Jessica. Mapping credentials by branch is the most straightforward way for beginners to achieve isolation between staging and production environments in the cloud.
