Abstract: Disclosed are examples related to data driven interfaces for decoupling management system components from a manufacturer or a platform of client devices managed by the management system. In some examples, among others, a system can generate a data driven interface template that can be used to cause rendering of a data driven user interface for configuring a profile payload of a device profile for the client device. The system can generate, based on values associated with the data driven user interface, a profile document in an instance in which values are obtained from the data driven user interface. In some aspects, the profile document is a generic representation of the profile payloads for the platform, the manufacturer or the type of the client device.

Abstract: Disclosed are various examples for enrollment of gateway enrollment for Internet-of-Things (IoT) device management. In some examples, a client device receives a gateway management installation package from a management service. The client device installs a gateway management application to the gateway device using the installation package. Enrollment credentials are entered through a user interface generated using the gateway management application and shown on the client device. The client device instructs the gateway management application enroll the gateway device with the management service. Usage of the enrollment credentials prevents a user from being exposed to gateway credentials that authenticate communications between the gateway device and the management service.

The computing device can then submit a first write request for the first local page to a first one of a plurality of memory hosts. The computing device can also submit a second write request for the second local page to a second one of the plurality of memory hosts. Additionally, the computing device can submit a third write request for the parity page to a third one of the plurality of memory hosts.

Abstract: Some embodiments of the invention provide a novel method for performing firewall operations on a computer. The method of some embodiments instantiates first and second firewall processes on the computer. These two processes are two separate processes, which in some embodiments have separate memory allocations in the memory system of the computer. The method uses the first firewall process to examine a data message to determine whether an encryption based firewall policy (e.g., a TLS-based firewall policy) has to be enforced on the data message. Based on a determination that the encryption-based firewall policy has to be enforced on the data message, the method provides metadata, which is produced by the first firewall process in its examination of the data message, to the second firewall process. The second firewall process then uses the provided metadata to perform an encryption-based firewall operation based on the encryption-based firewall policy.

Abstract: In some embodiments, a method configures, at a first host, an overlay channel for sending packets to check whether a failure has occurred at a workload. The first host and a second host are connected via a layer 3 network. The first host generates a packet to check whether the failure has occurred at the workload and encapsulates the packet. The first host sends the encapsulated packet to the second host using the overlay channel via the layer 3 network. The packet is decapsulated and forwarded to the workload at the second host.

Abstract: Some embodiments provide a novel method of performing health monitoring for resources associated with a global server load balancing (GSLB) system. This system is implemented by several domain name system (DNS) servers that perform DNS services for resources located at several geographically separate sites. The method identifies several different groupings of the resources. It then assigns the health monitoring of the different resource groups to different DNS servers. The method then configures each particular DNS server (1) to send health monitoring messages to the particular group of resources assigned to the particular DNS server, (2) to generate data by analyzing responses to the sent health monitoring messages, and (3) to distribute the generated data to the other DNS servers. The method in some embodiments is performed by a set of one or more controllers.

Abstract: Techniques for managing namespaces in a multi-cluster management (MCM) system to facilitate multi-cluster application development are provided. In one set of embodiments, a computer system executing the MCM system can create a workspace for an application being developed by a software development team of an organization, where the workspace is a logical grouping of namespaces on which the application has been or will be deployed, and where at least a subset of the namespaces can belong to different clusters of the organization. The computer system can then assign a member of the development team as a workspace administrator of the workspace, thereby enabling that development team member to perform management tasks on the workspace and its member namespaces via the MCM system (e.g., creating and adding namespaces to the workspace, setting access/image/network policies on the workspace, etc.), without help from the organization's IT staff.

Abstract: Certain embodiments described herein are directed to methods and systems for adding one or more nodes to a first cluster including a first node in a computer system. A method performed by the first node comprises receiving a first request from a second node to join the first cluster. The method also comprises retrieving a first cluster configuration associated with the first cluster from a distributed database through a first database server (DBS) and creating a second cluster configuration using the first cluster configuration and information received from the second node as part of the request. The method further comprises populating a first one or more local trust stores of a first one or more processes executing on the first node with a second one or more security certificates of a second one or more processes executing on the second node. The method further comprises writing the second cluster configuration to the distributed database and returning the second cluster configuration to the second node.

Abstract: Some embodiments provide a method of implementing context-aware routing for a software-defined wide-area network, at an SD-WAN edge forwarding element (FE) located at a branch network connected to the SD-WAN. The method receives, from an SD-WAN controller, geolocation route weights for each of multiple cloud datacenters across which a set of application resources is distributed. The application resources are all reachable at a same virtual network address. For each of the cloud datacenters, the method installs a route for the virtual network address between the branch network and the cloud datacenter. The routes have different total costs based at least in part on the geolocation metrics received from the SD-WAN controller. The SD-WAN edge FE selects between the routes to establish connections to the set of application resources.

Abstract: A method for creating overlay networking constructs to establish network connectivity between virtual routers and remote physical gateways is provided. An orchestrator receives a mapping between tenant network identifiers for multiple tenant networks and overlay network identifiers for multiple overlay networks. The orchestrator attaches a virtual router to a parent logical port of an overlay logical switch for connectivity between a physical gateway and the multiple tenant networks. The orchestrator creates multiple child logical ports that are sub-interfaces of the parent logical port. Each child logical port is uniquely identified by a tenant network identifier. The orchestrator connects multiple child logical switches to the multiple child logical ports according to the received mapping. Each child logical switch is uniquely identified by an overlay network identifier.
