Is Pulumi planning to support additional cloud provider APIs such as IBM & Alibaba?

Generally, we've been adding providers as there is demand. It's fairly easy to do if Terraform already has provider support implemented. I'd expect those to get added at some point, but I don't think there are immediate plans to do so.

@microscopic-florist-22719 has a private Alibaba package, so if you're interested in that, we can help out. Levi is absolutely right that we've been mostly focused on those with the greatest demand, but we're also willing to put in the work for specific requests if it helps you successfully use Pulumi.

@big-piano-35669 thanks. I found https://github.com/pulumi/pulumi-alicloud
