Abstract: Example methods are provided a network device to perform service insertion in a public cloud environment that includes a first virtual network and a second virtual network. In one example method, in response to receiving a first encapsulated packet from a first virtualized computing instance located in the first virtual network, the network device may generate a decapsulated packet by performing decapsulation to remove, from the first encapsulated packet. The method may also comprise identifying a service path specified by a service insertion rule, and sending the decapsulated packet to the service path to cause the service path to process the decapsulated packet according to one or more services. The method may further comprise: in response to the network device receiving the decapsulated packet processed by the service path, sending the decapsulated packet, or generating and sending a second encapsulated packet, towards a destination address.

Abstract: Example methods and systems are provided a network device to perform tunnel-based service insertion in a public cloud environment. An example method may comprise establishing a tunnel between the network device and a service path. The method may also comprise: in response to receiving a first encapsulated packet, identifying the service path specified by a service insertion rule; generating and sending a second encapsulated packet over the tunnel to cause the service path to process an inner packet according to one or more services. The method may further comprise: in response to receiving, from the service path via the tunnel, a third encapsulated packet that includes the inner packet processed by the service path, sending the inner packet processed by the service path, or a fourth encapsulated packet, towards a destination address of the inner packet.

Abstract: A system and method for connecting virtual computer networks in a public cloud computing environment using a transit virtual computer network uses a cloud gateway device in the transit virtual computer network that includes a first-tier logical router and a plurality of second-tier logical routers connected to the virtual computer networks. A source Internet Protocol (IP) address of outgoing data packets from a particular virtual computer network is translated at a particular second-tier logical router of the cloud gateway device from an IP address of the particular virtual computer network to an internal IP address from a particular pool of IP addresses. The outgoing data packets are then routed to the first-tier logical router of the cloud gateway device, where the outgoing data packets are transmitted a destination network from a particular interface of the first-tier logical router of the cloud gateway device.

Abstract: Example methods and computer systems are provided for east-west service insertion in a public cloud environment. An example method may comprise detecting an egress packet that is destined for a second endpoint located in the same virtual network as a first endpoint. The method may also comprise: in response to determination that service insertion is required, identifying a service path based on a service insertion rule; generating an encapsulated packet by encapsulating the egress packet with an outer header that is addressed from the first endpoint to a network device; and sending the encapsulated packet to cause the network device to send the egress packet towards the service path, thereby steering the egress packet towards the service path for processing.
