Platform engineering hinges on effective provisioning, which involves the automated creation and management of cloud resources to support self-service, governance, and streamlined developer workflows. A robust provisioning system, achieved by defining cloud resources as code and automating deployments, helps maintain consistent and auditable environments across development, staging, and production, reducing manual work and configuration drift. Key strategies include using version control for infrastructure definitions, automating changes with CI/CD pipelines, and separating configurations for different environments. Reusable components and service templates further enhance this process by encapsulating best practices and enabling quick, self-service provisioning without sacrificing security or compliance. By adopting these practices, platform engineering teams can reduce infrastructure change failure rates, increase self-service efficiency, and minimize infrastructure drift, ultimately transforming how developers interact with infrastructure.
