Techniques are disclosed for providing high performant packets processing capabilities in a virtualized cloud environment that enhance the scalability and high availability of the packets processing infrastructure. In certain embodiments disclosed herein, the VNICs functionality performed by network virtualization devices (NVDs) is offloaded from the NVDs to a fleet of computers, referred to as VNIC-as-a-Service System (or VNICaaS system). VNICaaS system is configured to provide Virtual Network Interface Cards (VNICs)-related functionality or service for multiple compute instances belonging to multiple tenants or customers of the CSPI. The VNICaaS system is capable of hosting multiple VNICs to process and transmit traffic in a distributed virtualized cloud networks environment. A single VNIC executed by the VNICaaS system can be used to process packets received from multiple compute instances.

Techniques for high performant virtual routing capabilities

Described are systems and methods of monitoring network health and traffic. Monitoring network health and traffic can include sending a request to a compute instance to trigger a response from the compute instance, monitoring, via a network virtualization device, communications from a virtual network interface card (VNIC) associated with the compute instance, storing information indicative of a last received packet by the VNIC, monitoring the stored information indicative of the last received packet to determine a health status of the compute instance associated with the VNIC, updating a table configured to track received responses from the compute instance, and notifying a downstream user of the health status of the compute instance.
