Abstract: Some embodiments provide an elastic architecture for providing a service in a computing system. To perform a service on the data messages, the service architecture uses a service node (SN) group that includes one primary service node (PSN) and zero or more secondary service nodes (SSNs). The service can be performed on a data message by either the PSN or one of the SSN. However, in addition to performing the service, the PSN also performs a load balancing operation that assesses the load on each service node (i.e., on the PSN or each SSN), and based on this assessment, has the data messages distributed to the service node(s) in its SN group. Based on the assessed load, the PSN in some embodiments also has one or more SSNs added to or removed from its SN group. To add or remove an SSN to or from the service node group, the PSN in some embodiments directs a set of controllers to add (e.g., instantiate or allocate) or remove the SSN to or from the SN group.

Abstract: Example methods and systems for connectivity service provisioning for a software-defined data center (SDDC) group are described. In one example, a computer system may detect an event that affects a first connectivity service connecting multiple members of the SDDC group. The computer system may obtain first routing information that is applicable in a first SDDC; and second routing information that is applicable in a second SDDC. In response to the event, the computer system may generate and send a first instruction towards the first SDDC and a second instruction towards the second SDDC to cause: (a) the first SDDC and second SDDC to establish a second connectivity service; (b) the first SDDC to update the first routing information to associate a first flow with the second connectivity service; and (c) the second SDDC to update the second routing information to associate a second flow with the second connectivity service.

Abstract: Some embodiments of the invention provide a method for implementing an edge device that handles data traffic between a logical network and an external network. The method monitors resource usage of a node pool that includes multiple nodes that each executes a respective set of pods. Each of the pods is for performing a respective set of data message processing operations for at least one of multiple logical routers. The method determines that a particular node in the node pool has insufficient resources for the particular node's respective set of pods to adequately perform their respective sets of data message processing operations. Based on the determination, the method automatically provides additional resources to the node pool by instantiating at least one additional node in the node pool.

Abstract: Components of a distributed data object are synchronized using streamlined tracking metadata. A target component of the distributed data object is detected as it becomes available and stale. A source component that is up-to-date and that mirrors the address space of the detected target component is identified. A set of mapped address ranges and a set of unmapped address ranges of the identified source component are obtained. A mapped address range of the target component that corresponds with an unmapped address range of the source component is identified. The identified mapped address range of the target component is then synchronized with the corresponding unmapped address range of the source component. Thus, unmapped address ranges are synchronized without using tracking metadata of the source component.
