Abstract: The disclosure provides an approach for distribution of functions among data centers of a cloud system that provides function-as-a-service (FaaS). For example, the disclosure provides one or more function distributors configured to receive a request for loading or executing a function, automatically determine an appropriate data center to load or execute the function, and automatically load or execute the function on the determined data center. In certain embodiments, the function distributors are further configured to determine an appropriate data center to provide storage resources for the function and configure the function to utilize the storage resources of the determined data center.

Abstract: In one example, resilient software application upgrades in a virtual datacenter is disclosed, in which network flow data is periodically obtained between a plurality of APPVMs and/or containers and deep packet inspection information from firewalls associated with the obtained network flow data in the virtual datacenter. Dependency relationships between the plurality of APPVMs and/or containers are then obtained based on the periodically obtained network flow data, the periodically obtained deep packet inspection information, and a network flow criteria. An upgrade that is about to happen to a software residing in one or more of the plurality of APPVMs and/or containers is determined. One or more of the plurality of APPVMs and/or containers affected by the software upgrade is determined based on the determined dependency relationships. Snapshots of the affected one or more of the plurality of APPVMs and/or containers are then obtained before initiating the software upgrade.

Abstract: Some embodiments provide a method for using flow-based load balancing to select a service endpoint from multiple service endpoints in a datacenter of an enterprise network for providing one or more services to client devices in the enterprise network. The method receives, from a network modeling appliance that categorizes service endpoints based on network data, a first set of service endpoints that provide at least one particular service for which a client connection is to be scheduled. The method generates an intersecting set of service endpoints based on the received first set of service endpoints and a second set of service endpoints identified by a load balancer that performs load balancing operations for data message flows to and from the plurality of service endpoints. Based on the generated intersecting set of service endpoints, the method selects a particular service endpoint for scheduling the client connection.

Abstract: Some embodiments provide a novel method of tracking connections in a network. The method receives an identification of a first network endpoint and a second network endpoint. The method then determines that the first network endpoint cannot directly address a packet flow to the second network endpoint. The method identifies an address translation rule of a network device that translates an address of the second network endpoint into a translated address. The method then determines that the first network endpoint can directly address a packet flow to the translated address. The method then identifies a route from the first network endpoint to the second endpoint through the network device that translates the address and displays the route including an identifier of the network device.

Abstract: A computer network optimization methodology is disclosed. In a computer-implemented method, components of a computing environment are automatically monitored, and have a feature selection analysis performed thereon. Provided the feature selection analysis determines that features of the components are in frequent communication and generating network latency. Provided the feature selection analysis determines that features of the components are not well defined, a similarity analysis of the features is performed. Results of the feature selection methodology are generated, and the components involved in the network traffic latency are reassigned to migrate the latency.

Abstract: In one example, a management node may include a storage device to store network device information associated with a plurality of network devices and physical hosts in a datacenter. Example network device information may include at least one of routing information and media access control (MAC) address information. Further, the management node may include a processor operable with the storage device and memory coupled to the processor. In one example, the memory may include a network topology generation unit to determine adjacency between the plurality of network devices in the datacenter using the routing information and/or media access control (MAC) address information associated with the plurality of network devices and generate a network topology including a network path between a source endpoint and a destination endpoint using the adjacency between the plurality of network devices.

Abstract: Techniques for reducing the startup latency of functions in a Functions-as-a-Service (FaaS) infrastructure are provided. In one set of embodiments, a function manager of the FaaS infrastructure can receive a request to invoke a function uploaded to the infrastructure and can retrieve information associated with the function. The retrieved information can include an indicator of whether instances of the function may be sticky (i.e., kept in host system primary memory after function execution is complete), and a list of zero or more host systems in the FaaS infrastructure that currently have an unused sticky instance of the function in their respective primary memories. If the indicator indicates that instances of the function may be sticky and if the list identifies at least one host system with an unused sticky instance of the function in its primary memory, the function manager can select the at least one host system for executing the function.
