Drift is automatically detected in configuration of services running in a management appliance of a software-defined data center. A method of automatically detecting drift includes: in response to a notification of a change in a configuration of a first service enabled for proactive drift detection, transmitting a first request to compute drift in the configuration of the first service to a plug-in of the first service, the first request including the change in the configuration of the first service; periodically, at designated time intervals, transmitting a second request to compute drift in the configuration of a second service enabled for passive drift detection, to the plug-in of the second service, the second request including a current state of the configuration of the second service; and notifying a desired state management service of the computed drift in the configuration of the first and second services.

Automatic drift detection of configurations of a software-defined data center that are managed according to a desired state

A method of managing configurations of a data center according to a desired state of the configurations includes retrieving a running state of the configurations, comparing the running state against a first desired state of the configurations and determining a drift of the running state from the first desired state, notifying a cloud control plane of the drift, and in response to an instruction issued by the cloud control plane to apply the desired state, configuring the data center according to a second desired state.

Desired state management of software-defined data center

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

A method of upgrading an application in a software-defined data center (SDDC) includes: deploying, by lifecycle management software executing in the SDDC, a second appliance, a first appliance executing services of the application at a first version, the second appliance having services of the application at a second version, the services in the first appliance being active and the services in the second appliance being inactive; expanding, by the lifecycle management software, state of the first appliance to support both the services at the first version and the services at the second version; replicating, by the lifecycle management software, the state of the first appliance to the second appliance; performing, by the lifecycle management software, a switchover to stop the services of the first appliance and start the services of the second appliance; and contracting, by the lifecycle management software, state of the second appliance to remove a portion unused by the services at the second version.

Reduced downtime during upgrade of an application hosted in a data center

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.

A method of managing configurations of a plurality of data centers that are each managed by one or more management servers, includes the steps of: in response to a change made to the configurations of one of the data centers, updating a desired state document that specifies a desired state of each of the data centers, the updated desired state document including the change; and instructing each of the data centers to update the configurations thereof according to the desired state specified in the updated desired state document. The management servers include a virtual infrastructure management server and a virtual network management server and the configurations include configurations of software running in the virtual infrastructure management server and the virtual network management server, and configurations of the data center managed by the virtual infrastructure management server and the virtual network management server.

Methods, apparatus, systems and articles of manufacture manage services in distributed systems are disclosed. An example apparatus includes at least one storage device, and at least one processor to execute instructions to at least perform an update of a first virtual machine in response to a determination that the first virtual machine is to enter a maintenance mode, the update based on storing a first service in a local service registry of the first virtual machine, in response to an unsuccessful update of the first virtual machine, restore the first virtual machine based on a snapshot, and provide the first service from a system service registry to a second virtual machine in response to a query from the second virtual machine for the first service.

Systems, methods and apparatus to manage services in distributed systems

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

A system for upgrading an application running on a virtual computing instance (VCI) can include a processing resource, a memory resource, and a VCI manager. The VCI manager can be executed by the processing resource and the memory resource and can be configured to cause a first VCI that is running the application to be copied as a second VCI, cause an updated version of the application to be installed on the second VCI, and cause a private network to be generated between the first VCI and the second VCI. The VCI manager can be further configured to cause data to be synchronized between the first VCI to the second VCI via the private network and cause the application running on the first VCI to be deactivated and cause the updated version of the application to be activated on the second VCI.

Near zero downtime application upgrade

Methods, apparatus, systems and articles of manufacture manage services in distributed systems are disclosed. An example distributed system includes a first virtual machine including a first storage device to store a first service registry for a plurality of virtual machines, and a second virtual machine, of the plurality of virtual machines, including a second storage device to store a second service registry for the second virtual machine, and a proxy service registrar having an interface to selectively provide a first service from the first service registry or the second service registry responsive to a query of the second virtual machine for the first service.
