Upgrade infrastructure with integration points having dynamically determined callbacks

A system comprising:

• one or more processors;
• and
• a memory comprising code stored thereon that, when executed by at least a first of the one or more processors, performs a method comprising:
• defining a plurality of integration points, wherein each of the plurality of integration points is associated with one of a first plurality of workflow processing points included in an upgrade workflow of an upgrade infrastructure or framework;
• and
• performing first processing by code of the upgrade infrastructure or framework that performs the upgrade workflow to upgrade a system including a cluster of appliances, wherein the upgrade includes upgrading, on all the appliances of the cluster, a first feature, facility or service of the system from a current version to a new version, wherein each appliance of the cluster includes a corresponding appliance dynamic integration point orchestrator, wherein the first processing further includes:
• storing, at a first predetermined location on each of the appliances of the cluster, a set of one or more code entities associated with a first integration point of the plurality of integration points;
• dynamically determining, at runtime during execution of the upgrade workflow by the code of the upgrade infrastructure or framework, the set of one or more code entities associated with the first integration point, wherein said dynamically determining at runtime the set of one or more code entities associated with the first integration point includes:
• each of the appliance dynamic integration point orchestrators of a respective one of the appliances dynamically determining the set of one or more code entities of the first integration point, including examining the first predetermined location of said respective one appliance and determining that the set of one or more code entities are stored in the first predetermined location of said respective one appliance;
• executing first executable code corresponding to the first plurality of workflow processing points, wherein a first workflow processing point of the first plurality is associated with the first integration point;
• and
• in response to said executing reaching the first workflow processing point corresponding to the first integration point, invoking each code entity of the set of code entities associated with the first integration point, wherein said each code entity performs first customized processing in connection with upgrading the first feature, facility or service in the system, wherein said invoking each code entity of the set associated with the first integration point includes:
• each of the appliance dynamic integration point orchestrators of a respective one of the appliances invoking each code entity of the set, as stored at the first predetermined location of the respective one appliance, resulting in execution of said each code entity on said respective one appliance.

A non-transitory computer readable medium comprising code stored thereon that, when executed by a processor, performs a method comprising:

• performing first processing by code of the upgrade infrastructure or framework that performs the upgrade workflow to upgrade a system including a cluster of appliances, wherein the upgrade includes upgrading, on all the appliances of the cluster, a first feature, facility or service of the system from a current version to a new version, wherein each appliance of the cluster includes a corresponding appliance dynamic integration point orchestrator, wherein the first processing further includes:
• storing, at a first predetermined location on each of the appliances of the cluster, a set of one or more code entities associated with a first integration point of the plurality of integration points;
• dynamically determining, at runtime during execution of the upgrade workflow by the code of the upgrade infrastructure or framework, the set of one or more code entities associated with the first integration point, wherein said dynamically determining at runtime the set of one or more code entities associated with the first integration point includes:
• each of the appliance dynamic integration point orchestrators of a respective one of the appliances dynamically determining the set of one or more code entities of the first integration point, including examining the first predetermined location of said respective one appliance and determining that the set of one or more code entities are stored in the first predetermined location of said respective one appliance;
• executing first executable code corresponding to the first plurality of workflow processing points, wherein a first workflow processing point of the first plurality is associated with the first integration point;
• and
• in response to said executing reaching the first workflow processing point corresponding to the first integration point, invoking each code entity of the set of code entities associated with the first integration point, wherein said each code entity performs first customized processing in connection with upgrading the first feature, facility or service in the system, wherein said invoking each code entity of the set associated with the first integration point includes:
• each of the appliance dynamic integration point orchestrators of a respective one of the appliances invoking each code entity of the set, as stored at the first predetermined location of the respective one appliance, resulting in execution of said each code entity on said respective one appliance.
