Technology section rewording and rephrasing feedback

[siforster]

The model has received the following feedback as part of issue #48:

• On Level 4, Helm is discussed as guidance vs. recommendation, "You’ll be expecting most of your software to be packaged with Helm with the feedback loop being closed as quickly as possible to reduce configuration drift."

  • TODO: Re-word to be a recommendation vs. direct guidance to use helm (i.e. Kustomize and other tools could do the job). I think this is well done in the earlier sections, "you may be starting to write Helm Charts..." sounds a lot better than "you're using Helm by now."

• Kustomize is discussed at lower levels of maturity and then isn't mentioned again when some folks are leveraging it at scale.

  • TODO: I think generalizing the customization tooling in early stages or group all customization tooling together and mention the group throughout (maybe a glossary term?). Alternately, replace all tooling-by-name with a generic "automated configuration and deployment tooling" blurb.

  • This isn't a Kustomize vs. Helm problem, it's a perception of the right tool for the right job potentially being ignored. There's other generators too that are popular.

• It makes sense to have the certificates from a sales point of view, but those could potentially be summarized at the beginning or end vs. sprinkled along the model.

The group agreed in the community meeting of 24 January 2023 that the the model be reworded/rephrased in line with these recommendations.
