things like terraform are great for the initial setup, but there is a lack for tooling around recurring management -- although, docker does help the story for having ephemeral environments quite a bit

it would be great to see developer environments be able to consume helm charts etc to create production-like environments but the overall sprawl around the variety of cloud-hosted or other SaaS products that are used in applications nowadays makes that quite hard - imo would be really nice to have a dev-tenancy variant for things like MongoDB, Datadog, etc
