Detection and mitigation of denial of service attacks in distributed networking environments

A system comprising:

• a processor;
• and
• a memory storing instructions that, when executed by the processor, configure the system to:
• for a first entity deployed in a first region of a plurality of regions of a cloud services provider network, monitor a flow of network traffic data originating from the first entity and destined to a second entity remote from the first entity, the second entity deployed in a second region of the plurality of regions of the cloud services provider network;
• based at least in part on the monitoring, determine that a network traffic data value associated with a network packet in the flow of network traffic data originating from the first entity exceeds a first threshold value, wherein the first entity is a first customer network in a first data center of the cloud services provider network and the second entity is a second customer network in a second data center of the cloud services provider network;
• responsive to the determining, identify an action to be taken to mitigate the threshold value being exceeded;
• and
• perform the action to mitigate the threshold value being exceeded.

A non-transitory computer-readable medium having program code that is stored thereon, the program code executable by one or more processing devices for performing operations comprising:

• for a first entity deployed in a first region of a plurality of regions of a cloud services provider network, monitoring a flow of network traffic data originating from the first entity and destined to a second entity remote from the first entity, the second entity deployed in a second region of the plurality of regions of the cloud services provider network;
• based at least in part on the monitoring, determining that a network traffic data value associated with a network packet in the flow of network traffic data originating from the first entity exceeds a threshold value, wherein the first entity is a first customer network in a first data center of the cloud services provider network and the second entity is a second customer network in a second data center of the cloud services provider network;
• responsive to the determining, identifying an action to be taken to mitigate the threshold value being exceeded;
• and
• performing the action to mitigate the threshold value being exceeded.
