Greetings Professionals,

Can any one help me on understanding the difference between AWS Opswork Chef Automate and Licensed chef(Host/On premise) does the licensed one has more features compared to AWS provisioned chef automate servers. what are the advantages of using AWS Opswork chefautomate and licensed Opscode Chef software.

Please provide specific detailed information of both the use cases and also we are using there are 3rd party softwares where they could able to integrate with licensed chef but could not able to do the same with AWS provisioned chef automate.

Thank you
