I think this list makes lot of sense. I believe lot of information is already there which can help you build the effective orchestration layer. In no specific order here is the vCAC Blogger list, I refer and love reading them.
I’m pretty sure list is going to be big. I have used all above blogs to learn vCAC product. If any blog I have missed please feel free to leave it in comment. I will update it. Idea to share the active vCAC/vRA bloggers.
