Cloud Foundry was created by the company behind Spring/Spring Boot.
You can audit a course on this topic for free at https://www.edx.org, but if you want a badge for your Linked In/CV then you need to spend money.
Cloud Foundry also has a certification path which cost money.
In addition to or perhaps in contrast to Cloud Foundry, you may want to know about AWS.
I'm unsure if you have mentioned anything regarding databases. You may want to know at least the basics of either SQL and/or NoSQL systems.
