Where I can find the links to download community edition

No more Links, you have to register to get access to cloud instance

This means, there is only a cloud solution now?

Yes

and the existing on premise solutions will not be developed further?

Actually, for now there is still support for on premise solution but it will be discontinued later as ii heard. To get support, you will have to communicate with your CSM

Thank you @Joseph3
Indeed Community (free) edition is only on cloud now.

Ok, I think we have still an onpremise version running. Can you say me when the product will run out of support?
