Start with the two linked Kubernetes and Heptio references, then inspect the website's existing post structure and contribution guidance. Draft an article for architects and SREs covering CRDs, their benefits and weaknesses, and performance implications, with the requested screenshots; done means the post and assets are ready for review.
