An example method of deploying a logical network platform in a virtualized computing system, the virtualized computing system including a host cluster and a virtualization management server connected to a physical network, the host cluster having hosts and a virtualization layer executing on hardware platforms of the hosts is described. The method includes receiving, at the virtualization management server, a declarative specification describing a proposed state of the logical network platform; deploying, by the virtualization management server, a network manager of the logical network platform in response to the proposed state in the declarative specification; and deploying, by the virtualization management server in cooperation with the network manager, binaries to the hosts in the host cluster.

Logical network platform install and upgrade in a virtualized computer system

A method of upgrading a VIM server appliance includes: creating a snapshot of logical volumes mapped to physical volumes that store configuration and database files of virtual infrastructure management (VIM) services provided by a first VIM server appliance to be upgraded; after the snapshot is created, expanding the configuration and database files to be compatible with a second VIM server appliance; replicating the logical volumes which have been modified as a result of expanding the configuration and database files, in the second VIM server appliance; after replication, performing a switchover of VIM services that are provided, from the first VIM server appliance to the second VIM server appliance; and upon failure of any of the steps of expanding, replicating, and performing the switchover, aborting the upgrade, and reverting to a version of the configuration and database files that was preserved by creating the snapshot.

Lifecycle management of virtual infrastructure management server appliance

Distributed tracing is applied during an upgrade from a first management appliance to a second management appliance. The distributed tracing method includes generating a parent span that encapsulates states of the overall workflow, including a span context that contains a trace identifier and a span identifier, and generating a plurality of child spans. Each child span encapsulates states that represent a piece of the workflow and contains a reference to the parent span context. The states of the child spans include an error tag that indicates whether the piece of the workflow associated with the child span executed with an error. Because child spans may be generated for a piece of the workflow that is executed by a service running in the first or second management appliance, the span context for the parent span is persisted by the first management appliance and replicated for use by the second management appliance.

Real-time cross appliance operational intelligence during management appliance upgrade

A method of reserving hardware resources for management appliances of a software-defined data center (SDDC) that have been deployed onto one or more hosts of a cluster of hosts, includes reserving hardware resources of the cluster for a resource pool that has been created for the management appliances, the hardware resources including at least processor resources of the hosts and memory resources of the hosts, and assigning the management appliances to the resource pool created for the management appliances. The management appliances share the hardware resources of the cluster with one or more other resource pools and, after the steps of reserving and assigning, are allocated at least the hardware resources that have been reserved for the resource pool created for the management appliances.

Hardware resource management for management appliances running on a shared cluster of hosts

In one example, a management node and an infrastructure node external to the management node may be identified in a cloud computing environment. The management node may execute a centralized management service and the external infrastructure node may execute a first infrastructure service that handles at least one infrastructure network function for the centralized management service. Further, a second infrastructure service may be deployed on the management node. Data in the first infrastructure service may be replicated to the second infrastructure service. Furthermore, the centralized management service in the management node may be repointed to the second infrastructure service such that the second infrastructure service is to operate within the management node.

System and method for embedding external infrastructure services into management nodes

A system and method for establishing trust between management entities with different authentication mechanisms in a computing system utilizes a token exchange service to acquire a second security token used in a second management entity in exchange for a first security token used in a first management entity. In an embodiment, an endpoint is set at the first management entity as an authentication endpoint for the second management entity, which is used to authenticate a request with the second security token that is sent from the first management entity to the second management entity. After authentication, the request is processed at the second management entity and a response is transmitted to the first management entity.

System and method for establishing trust between multiple management entities with different authentication mechanisms

A host computing system may include a processor and a memory coupled to the processor. The memory may include an auto-discovery module to broadcast a message to a set of management nodes in a data center. The message may include a configuration policy. Further, the auto-discovery module may receive an acknowledgment message from a management node. The acknowledgment message may indicate that the management node supports the configuration policy. Furthermore, the auto-discovery module may establish a trust relationship with the management node in response to receiving the acknowledgment message. Further, the auto-discovery module may enable the host computing system to add to a cluster managed by the management node upon establishing the trust relationship.

Host computing systems placement in data centers

Aspects of updating or upgrading a management system for a virtualized computing environment are described. In some aspects, a virtualization management system that manages a virtualized computing environment can be upgraded or updated with limited downtime of the system by deploying a new instance of the system and subsequently assigning a network address of the previous instance to the new instance once it is deployed in the environment.

Upgrade implementation of a virtualization management system

System and methods for simulating an end-to-end upgrade process are provided. The method may include collecting, by an upgrade simulator, a system inventory from a production system. The system inventory includes the production system's hardware configuration. The method may include, in response to a determination that the system inventory is compatible with an upgrade software, configuring, by the upgrade simulator, a simulated system having a downsized hardware configuration compared to the production system's hardware configuration. The method may further include upgrading, by the upgrade simulator, the simulated system using the upgrade software, and evaluating, by the upgrade simulator, the simulated system operating with the upgrade software.

Simulating end-to-end upgrade process in production environment

In one example, a cloud computing environment may be probed to detect an actual topology including connectivity between infrastructure security nodes and management nodes. Each management node may execute a corresponding centralized management service. Each infrastructure security node may execute a corresponding infrastructure security service that handles at least one infrastructure security function. Further, a set of candidate topologies may be generated based on the actual topology. Each candidate topology may indicate a way to replicate the infrastructure security service into the management nodes. Furthermore, a replication partner associated with each of the management nodes may be determined based on a selection of one of the candidate topologies. An operation to deploy the infrastructure security service on the management nodes may be executed based on the selected one of the candidate topologies and the determined replication partners to form an embedded linked mode architecture.
