+[Pulumi](https://www.pulumi.com/) is a tool in the infrastructure-as-code space 
+that is quite similiar to [Terraform](https://www.terraform.io/) in that it also 
+provide a declarative way to provision cloud infrastructure and services. 
+What makes it interesting is that all configuration is done in one of currently
+4 supported general-purpose languages/runtimes: 
+* Javascript/Typescript
+* Python
+* .NET Core
+* Go
+
+This differs from the Terraform approach which is using it's own domain specific 
+'Terraform Configuration Language'. While Terraform kept this language 
+intentionally small and limited in functionality in order to make it purely
+declarative sometimes there is the need to abstract over configuration
+to keep your configs "DRY". For this there are modules in Terraform but sometimes
+all you need is a small function to iterate an input. 
+
+This is where Pulumi shines by allowing you to use the powers of the chosen
+programming language to build whatever abstractions you need to get the job done.
+
+We currently test-drive it in small projects to compare it over Terraform.
