Mechanism for facilitating spin mode-based dynamic updating of application servers in an on-demand services environment

An apparatus comprising a data processing device, wherein the data processing device to facilitate:

• selection and retirement module to maintain a cluster of computing device, wherein each computing device includes an application server associated with a version of an application software,
• wherein the selection and retirement module is further to retire one or more computing devices from the cluster of computing devices for upgrading from a first version to a second version;
• processing module to receive one or more requests to initiate one or more organizational tasks to be processed by the one or more computing devices using the second version:
• and
• spin mode module to dynamically hold, the one or more requests in a wait stage while the one or more computing devices are being upgraded, via upgrade module, from the first version to the second version,
• wherein, upon upgrading of the one or more computing devices from the first version to the second version, the spin mode module is further to selectively route, the one or more requests from the wait stage to the upgraded one or more computing devices for processing by the second version,
• wherein dynamically holding further includes continuously holding, in the wait state, one or more requests to be processed by a third version while the one or more computing devices are being upgraded from the first version to the third version, wherein the wait stage includes a spin mode, and
• wherein, upon upgrading the one or more computing devices, selectively routing the one or more requests from the wait stage to the one or more computing devices for processing by the third version.

A non-transitory machine-readable medium having stored thereon instructions which, when executed by a machine, cause the machine to:

• maintain a cluster of computing device, wherein each computing device includes an application server associated with a version of an application software;
• retire one or more computing devices from the cluster of computing devices for upgrading from a first version to a second version;
• receive one or more requests to initiate one or more organizational tasks to be processed by the one or more computing devices using the second version;
• dynamically hold, the one or more requests in a wait stage while the one or more computing devices are being upgraded from the first version to the second version;
• and
• upon upgrading of the one or more computing devices from the first version to the second version, selectively route, the one or more requests from the wait stage to the upgraded one or more computing devices for processing by the second version,
• wherein dynamically holding further includes continuously holding, in the wait state, one or more requests to be processed by a third version while the one or more computing devices are being upgraded from the first version to the third version, wherein the wait stage includes a spin mode, and
• wherein, upon upgrading the one or more computing devices, selectively routing the one or more requests from the wait stage to the one or more computing devices for processing by the third version.
