Abstract: Described herein are systems, methods, and software to dynamically manage resources across software-defined data centers. In one implementation, a monitoring service obtains flow information associated with physical network interfaces (PNICs) and virtual networking interfaces (VNICs) across a plurality of software-defined data centers (SDDCs). The monitoring service further determines when the flow information associated with the one or more workloads satisfy criteria and, in response to satisfying criteria, generates an update to a configuration associated with at least one SDDC of the plurality of SDDCs based on the flow information.

Abstract: The disclosure provides an approach for seamless hand-off of data traffic in public cloud environments. Techniques are provided for activating an edge services gateway (ESG) virtual computing instance (VCI) on a new host. Prior to activating the ESG VCI on the new host, an underlay routing table is reprogrammed to associate a first IP address of a first tunnel endpoint (TEP) with a first network interface of an old host and to associate a second IP address of a second TEP with a second network interface of the new host. The routing table associates a third IP address of the ESG VCI with the first network interface. After activating the ESG VCI, a packet having as a destination address the third IP address is received at the first network interface and is encapsulated, by the first TEP, with an outer header having as a destination address the second IP address.

Abstract: Some embodiments provide a novel method for configuring managed forwarding elements (MFEs) to handle data messages for multiple logical networks that are implemented in a data center at the MFEs and to provide gateway service processing (e.g., firewall, DNS, etc.). A controller, in some embodiments, identifies logical networks implemented in the datacenter and MFEs available to provide gateway service processing and assigns gateway service processing for each logical network to a particular MFE. The MFEs, in some embodiments, receive data messages from endpoints in the logical networks that are destined for an external network. In some embodiments, the MFEs identify that the data messages require gateway service processing before being sent to the external network. The MFEs, in some embodiments, identify a particular MFE that is assigned to provide the gateway service processing for logical networks associated with the data messages.
