  • Patent number: 11582217
    Abstract: The disclosed system implements techniques to secure communications for injecting a workload (e.g., a container) into a virtual network hosted by a cloud-based platform. Based on a delegation instruction received from a tenant, a virtual network of the tenant can connect to and execute a workload via a virtual machine that is part of a virtual network that belongs to a resource provider. To secure calls and authorize access to the tenant's virtual network, authentication information provided with a call from the virtual network of the resource provider may need to match authorization information made available via a publication service of the cloud-based platform. Additionally or alternatively, an identifier of a NIC used to make a call may need to correspond to a registered name of the resource provider for the call to be authorized. These checks provide increased security by preventing unauthorized calls to the tenant's virtual network.

  • Patent number: 11063857
    Abstract: Techniques are described herein that are capable of monitoring connectivity and latency of network links in virtual networks. For instance, a ping agent injects first ping packets into network traffic on behalf of hosts in the virtual network. The ping agent monitors incoming packets to identify first ping response packets, which are in response to the first ping packets, among the incoming packets. A ping responder rule that is included in inbound packet filter rules for a port in a virtual switch intercepts second ping packets in the network traffic. The ping responder rule converts the second ping packets into second ping response packets and injects the second ping response packets into outbound packet filter rules to be transferred to sources from which the second ping packets are received.

Based on a delegation instruction received from a tenant, a virtual network of the tenant can connect to and execute a workload via a virtual machine that is part of a virtual network that belongs to a resource provider. To secure calls and authorize access to the tenant's virtual network, authentication information provided in association with a call from the virtual network of the resource provider may need to match authorization information made available via a publication service of the cloud-based platform. Moreover, an identifier of a NIC used to make a call may need to correspond to a registered name of the resource provider for the call to be authorized. These checks provide increased security by preventing unauthorized calls from accessing the tenant's virtual network.
