The blog post provides a detailed exploration of deploying a PERN stack application—comprising PostgreSQL, Express, React, and Node—onto AWS, utilizing Pulumi Crosswalk to streamline the process. It highlights the PERN architecture, which involves a database, a stateless server, a client-side server, and user interaction, and emphasizes the advantage of using infrastructure as code, specifically with TypeScript, to align the development of both application and infrastructure. The guide walks through initializing a Pulumi project, configuring PostgreSQL and AWS settings, and setting up a Virtual Private Cloud (VPC) and other necessary AWS components. It explains how to use Pulumi’s Dynamic Provider to manage database schemas and tables and demonstrates deploying the application’s server-side and client-side services to AWS’s Elastic Container Service (ECS) using Crosswalk for efficient infrastructure management. The post concludes by noting the flexibility and scalability offered by Pulumi Crosswalk, with a promise to cover Kubernetes integration in the following week.
