Hi my new role uses Pulumi across Python/Node where each repo has its own decoupled infra. I am moving to create a monorepo for all our infrastructure. I come from a Terraform background and was wondering what is the recommended way to do it? Can a monorepo with Pulumi infrastructure exists across different languages? I have a strict requirement that my platform team creates reusable modules across things such as AWS S3/RDS/etc. Is this possible with Pulumi? Are there any examples showing how this works?

The general way is to use multiple stacks. 1, command infra stack, like vpc, dns, s3, etc 2. app-specific stacks, like ecs, alb, etc. these can use stack ref, to access resources defined in infra stack

Also you can publish component libraries across languages. Since you're just getting started, I recommend adopting this from day 1 and setting standards for it, it's really useful in heterogenous environments. https://www.pulumi.com/docs/iac/using-pulumi/build-a-component/ https://www.pulumi.com/blog/registry-component-api-docs/

hey @magnificent-addition-39385, have a look also into this article https://www.pulumi.com/blog/iac-best-practices-structuring-pulumi-projects/ and series. Will help you a lot in this topic.

Thanks everyone
