Pulumi has introduced architecture templates to streamline the process of setting up new cloud projects like static websites, containers, and Kubernetes clusters. These templates are essentially Pulumi projects with additional configurations, allowing users to quickly bootstrap projects. The process of creating a custom template involves starting with a Pulumi project, adding resources, and configuring settings that can be customized by users, such as AWS region and website details. Once configured, these templates can be tested locally and published for broader use by sharing them via Git URLs or GitHub gists. Additionally, the "Deploy with Pulumi" button provides a seamless way for users to create projects directly from templates in their web browsers, enhancing accessibility and collaboration. The ease of creating and sharing Pulumi templates encourages experimentation and facilitates the deployment of cloud infrastructure projects.
