Systems and methods for installing, managing, and provisioning applications

A system for upgrade deployment comprising:

• one or more processors and one or more memory devices operably coupled to the one or more processors, the one or more memory devices storing executable and operational code effective to cause the one or more processors to:
• receive an instruction to upgrade a module installed on a plurality of nodes;
• sequentially perform, for each node of the plurality of nodes:
• providing an upgraded module for the node;
• deactivating a former module for the node;
• installing the upgraded module for the node;
• evaluating performance of the upgraded module for the node;
• and
• if the performance is found to improve, retaining the upgraded module for the node, otherwise restoring the former module for the node;
• receive external traffic from a plurality of users;
• distribute the external traffic among the plurality of nodes according to a load balancing approach;
• distribute an excess amount of the external traffic to a selected node of the plurality of nodes, the excess amount of the external traffic being greater than amounts of the external traffic distributed to other nodes of the plurality of nodes according to the load balancing approach;
• increase the excess amount of the external traffic distributed to the selected node of the plurality of nodes until failure of the selected node of the plurality of nodes occurs;
• monitor the selected node of the plurality of nodes;
• identify one or more failure points according to the monitoring of the selected node of the plurality of nodes, the one or more failure points identified comprises one or more resources failing to meet a specified quality of service;
• adjust the excess amount of the external traffic distributed to the selected node of the plurality of nodes;
• and
• distribute the external traffic among the plurality of nodes according to the adjusting the excess amount of the external traffic distributed to the selected node of the plurality of nodes.

A computer program product for upgrade deployment, the computer program product being embodied in a non-transitory computer readable storage medium and comprising computer instructions for:

• receiving an instruction to upgrade a module installed on a plurality of nodes;
• sequentially performing for each node of the plurality of nodes:
• providing an upgraded module for the node;
• deactivating a former module for the node;
• installing the upgraded module for the node;
• evaluating performance of the upgraded module for the node;
• and
• if the performance is found to improve, retaining the upgraded module for the node, otherwise restoring the former module for the node;
• receiving external traffic from a plurality of users;
• distributing the external traffic among the plurality of nodes according to a load balancing approach;
• distributing an excess amount of the external traffic to a selected node of the plurality of nodes, the excess amount of the external traffic being greater than amounts of the external traffic distributed to other nodes of the plurality of nodes according to the load balancing approach;
• increasing the excess amount of the external traffic distributed to the selected node of the plurality of nodes until failure of the selected node of the plurality of nodes occurs;
• monitoring the selected node of the plurality of nodes;
• identifying one or more failure points according to the monitoring of the selected node of the plurality of nodes, the one or more failure points identified comprise one or more resources failing to meet a specified quality of service;
• adjusting the excess amount of the external traffic distributed to the selected node of the plurality of nodes;
• and
• distributing the external traffic among the plurality of nodes according to the adjusting the excess amount of the external traffic distributed to the selected node of the plurality of nodes.
