SYSE.33:4.3 - Choose a creation and change mechanism

Compare a controlled push procedure with a pull-and-reconcile arrangement for the actual resources and operating conditions. A push procedure can be adequate for a bounded short-lived test environment. Continuous reconciliation may help where drift and continuing desired state are material. Neither choice removes the need to observe the resulting environment.

The OpenGitOps v1.0.0 principles supply a specific line: versioned declarative desired state, automatic retrieval and continuing attempts to reconcile observed state. Use it where those conditions fit. Do not infer successful convergence from a committed declaration or an agent’s presence.

For either mechanism, define the operation’s bounded target, permitted changes and behavior after partial completion. Know how to identify resources already created by an attempt. Repeat a step only when its replay behavior is qualified; a repeated creation request must not silently create a second independently chargeable or stateful resource.
