Pulumi, an Infrastructure as Code (IaC) platform, utilizes various programming languages to manage cloud resources, and this article focuses on using TypeScript with Pulumi to create infrastructure on Amazon Web Services (AWS). It highlights the benefits and challenges of Infrastructure as a Service (IaaS) and IaC, emphasizing the automation, scalability, and security offered by these solutions, while noting potential issues like dependency on a single provider and the complexity of migrating between providers. The article provides a practical example of setting up an AWS S3 bucket using Pulumi and TypeScript, detailing the necessary project layout, configuration, and deployment steps, and explaining the use of components for resource management. It also compares Pulumi to other tools like AWS Cloud Development Kit (CDK), suggesting that Pulumi offers more readable code and more efficient deployments. Additionally, it underlines the importance of simplicity and precision in writing infrastructural code, as it differs significantly from applicative code, particularly in terms of testing and code duplication.
