Martin Atkins a6abe0c8a0 engine/planning: Incomplete stub of managed resource instance planning
This sketches the main happy path of planning for a desired managed
resource instance, though doesn't include all of the possible variations
that authors can cause with different configuration settings.

The main goal here is just to illustrate how the planning step might
interact with the work done in the eval system. If we decide to go in this
direction then we'll need to bring over all of the complexity from the
traditional runtime into this codepath, or possibly find some way to reuse
that behavior directory from "package tofu" in the short term.

OpenTofu

OpenSSF Best Practices

OpenTofu is an OSS tool for building, changing, and versioning infrastructure safely and efficiently. OpenTofu can manage existing and popular service providers as well as custom in-house solutions.

The key features of OpenTofu are:

  • Infrastructure as Code: Infrastructure is described using a high-level configuration syntax. This allows a blueprint of your datacenter to be versioned and treated as you would any other code. Additionally, infrastructure can be shared and re-used.

  • Execution Plans: OpenTofu has a "planning" step where it generates an execution plan. The execution plan shows what OpenTofu will do when you call apply. This lets you avoid any surprises when OpenTofu manipulates infrastructure.

  • Resource Graph: OpenTofu builds a graph of all your resources, and parallelizes the creation and modification of any non-dependent resources. Because of this, OpenTofu builds infrastructure as efficiently as possible, and operators get insight into dependencies in their infrastructure.

  • Change Automation: Complex changesets can be applied to your infrastructure with minimal human interaction. With the previously mentioned execution plan and resource graph, you know exactly what OpenTofu will change and in what order, avoiding many possible human errors.
