Managing secrets across multi-cloud infrastructures is a challenge that Pulumi seeks to address with its Infrastructure as Code (IaC)-based strategy, which centralizes secret and configuration management within Pulumi's platform. This approach aims to mitigate the issue of "secret sprawl," where sensitive information is dispersed across multiple systems, leading to inconsistencies and security vulnerabilities. By utilizing Pulumi ESC (Environment and Stack Configuration), secrets and configurations are centrally defined and automatically synchronized across various platforms, such as AWS Secrets Manager, Azure Key Vault, and GCP Secrets Manager. Pulumi's method reduces the manual overhead and errors associated with traditional secret management, offering automated updates through scheduled synchronizations or real-time updates via webhooks when secrets are modified. This centralized system enhances security audits and compliance efforts by maintaining a single source of truth for secret management. Pulumi encourages users to explore its documentation and community resources to fully harness the potential of this tool in simplifying and securing secret management processes.
