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

Methods, apparatus, systems, and articles of manufacture are disclosed for high availability (HA) application migration in a virtualized environment. An example apparatus includes at least one memory, instructions in the apparatus, and processor circuitry to at least one of execute or instantiate the instructions to identify an HA slot in a virtual server rack, the HA slot to facilitate a failover of an application executing on a first virtual machine (VM) in the virtual server rack, the first VM identified as a protected VM, deploy a second VM in the HA slot, transfer data from the first VM to the second VM, and, in response to not identifying a failure of at least one of the first or second VMs during the transfer, trigger a shutdown of the first VM, and synchronize migration data associated with the virtual server rack to identify the second VM as the protected VM.

Systems, methods, and apparatus for high availability application migration in a virtualized environment

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 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.
