Chef Server license

Hi, folks
I have an environment that contains a fleet of servers that run Windows Server. I need to automate installing different software on it using chef. My question is do I have to purchase a license to use Chef server? and how to buy if I have to?

Thanks in advance

You need a license to use any of the latest Chef Branded software. The Enterprise license that is most common includes Chef Infra Server, Automate, and Chef Infra Client. If you go to the downloads section of our website it'll ask you to fill out a contact form before allowing the download and then somebody from sales will contact you within a couple of days. It may be next week due to US holiday coming up this week.

@Stromweld Thank you for your reply

@Stromweld Thanks for your support but I have been confused about something and I would be grateful if you give a hand to understand it, what about the following resources? what is the differnece between this license which I suppose to be open source and the commercial license that you talk about?

I will put another two links in another comments because of the limitations of comments.

@Stromweld GitHub - chef/automate: Chef Automate provides a full suite of enterprise capabilities for maintaining continuous visibility into application, infrastructure, and security automation.

Chef code is open source. After chef-client 14.x, starting with chef-client 15.x the license and terms of use changed for the chef brand/trademarks. Much like Redhat the code is opensource but must be compiled and remove all references to chef copyrighted brands and trademarks like centOS did with RHEL to be legally used. Otherwise purchase of a license from Chef enables you to use the Chef Branded, compiled, and supported Chef-Client with support from Chef if there are any issues.
