Pulumi is an infrastructure-as-code platform that lets teams define and manage cloud infrastructure in general-purpose languages such as TypeScript, Python, Go and .NET, rather than in a separate configuration language. Its SDKs and command-line tool are open source under the Apache 2.0 licence. Pulumi Cloud, a hosted service, manages organisation access, security and deployments, and the company states that it can also be deployed on an organisation's own infrastructure with the Enterprise edition.
Pulumi is a privately held company headquartered in Seattle, Washington, founded in 2017. Its public pages do not state where Pulumi Cloud stores customer data, so the hosting location should be confirmed with the vendor before use. As a US company it falls under US jurisdiction for data it controls. For a European organisation the open-source SDKs can run on local infrastructure, while the hosted control plane is a separate decision that needs a data processing review.
