Note

We saw that using workspaces with Google Cloud projects is an easy way to manage nearly identical environments. All we have to do is to create an additional workspace and supply different values in our variable definitions file. However, one of the major limitations of this approach is that the environments must be nearly identical.

Using our example, let’s say we want to have two small servers in the development environment, but in the production environment, we want to have two medium and one large server. Provisioning two servers of different sizes is easy, as we can specify different server sizes in the variable definitions file. However, having a third server of a different configuration only in production is more challenging. We could define a combination of conditional expressions and a count meta...
