Pulumi is an innovative infrastructure-as-code (IaC) technology that empowers developers to manage and provision cloud resources using familiar programming languages like TypeScript, Python, and more, rather than traditional configuration languages. This approach allows developers to leverage existing skills without the need to learn a new IaC language, streamlining the adoption process. Pulumi's flexibility facilitates the integration of complex logic into the infrastructure deployment process, enhancing automation and efficiency. With comprehensive SDKs, Pulumi supports a wide range of cloud platforms, including AWS, Azure, and Google Cloud, making it a versatile choice for diverse cloud environments. Key features include seamless integration with CI/CD pipelines, robust resource management, and the ability to migrate existing infrastructure, offering a powerful toolset for modern cloud infrastructure management.
Infrastructure-as-Code is a way for provisioning infrastructure by describing the state of the infrastructure you want to get as a program that can be interpreted and executed.
Pulumi is an infrastructure-as-code tool that provisions and manages cloud resources using general-purpose programming languages, enabling teams to apply software engineering practices to infrastructure delivery.
Pulumi is a strong fit when infrastructure needs to be treated as software, but it introduces typical software concerns such as dependency management, versioning, and testing discipline. Teams should also plan for state management practices and provider version pinning to keep deployments deterministic. For an overview of the approach, see Pulumi documentation.
Common alternatives include Terraform, AWS CloudFormation, and Azure Bicep, with the best choice depending on language preferences, governance requirements, and the target cloud footprint.
Our experience with Pulumi helped us build repeatable patterns, internal tooling, and delivery playbooks for teams adopting infrastructure-as-code with real software engineering practices (testing, modularization, and code review) across multiple cloud environments.
Some of the things we did include:
This delivery experience helped us accumulate significant knowledge across migrations, platform builds, and day-2 operations, and it enables us to implement high-quality Pulumi setups that are maintainable, secure, and aligned with how engineering teams actually ship software.
