Pulumi simplifies the deployment of cloud infrastructure through code, enabling flexible configurations that can span multiple regions, accounts, or clusters for improved performance, scalability, and resilience. While typically deployments involve a single stack and region, Pulumi allows for a more dynamic setup, as illustrated by the deployment of an AWS RDS primary database in one region and a read replica in another, all managed from a single Pulumi program. This approach uses both implicit configuration via the CLI and explicit provider configuration set programmatically, which allows for precise and flexible control over resource deployment. The example highlights the capability to manage infrastructure across regions, showcasing Pulumi’s adaptability in handling complex, multi-regional architectures while leveraging the full power of programming languages to orchestrate deployments effectively.
