Pulumi, an Infrastructure as Code (IaC) tool, supports a variety of programming languages such as TypeScript, JavaScript, and Python, enabling users to standardize tasks like VPC builds, deploy virtual machines on VSphere, and manage infrastructure through CI/CD pipelines. Recent blog posts highlight practical applications of Pulumi, including setting up CircleCI on Google Kubernetes Engine and comparing Pulumi's versatility with Terraform's more rigid structure, as discussed by Jon Hathway of HATech. Cody De Arkland demonstrates the creation of VMWare VSphere virtual machines, emphasizing how Pulumi allows for configuration management directly in code, which enhances collaboration and integration into CI/CD workflows. These insights underscore Pulumi's potential to streamline DevOps processes by incorporating infrastructure management within source control systems, thus facilitating more efficient and collaborative deployments.
