@Lyrica Thank you for reaching out to Microsoft Q&A. We sincerely apologize for the delay in response to your issue.

I understand that you are seeing a Ddos attack to your Ubuntu server. Azure provides a few options for this situation:

Azure Ddos protection standard, combined with application design best practices, provides enhanced DDoS mitigation features to defend against DDoS attacks. However, please note that currently Azure DDOS service does not allow you to manually block specific IP addresses. For that, you can use Azure Firewall which uses threat intelligence-based filtering so you can protect your virtual network by denying traffic from/to known malicious IP addresses and domains. It might also help if you can go through this Network Security baseline documentation and determine if additional security measures are required or missing.

Here are some reference architecture for Ddos protection. Hope this helps.
Please let us know if you have any further questions and we will be glad to assist you further. Thank you!
