Systems and methods for preventing gray failures in cloud applications

A system, comprising:

• a plurality of cloud pools, each cloud pool hosted by cloud hardware;
• a plurality of cloud applications in each of the plurality of cloud pools;
• a health monitoring application for the plurality of cloud applications in each of the plurality of cloud pools;
• a plurality of global load balancers, each load balancer in communication with a subset of the plurality of cloud pools;
• a listener application;
• and
• a remediation application;
• wherein:
• the listener application is configured to receive, from each health monitoring application, a health status of the plurality of cloud applications in the plurality of cloud pools;
• the listener application is configured to receive a maintenance schedule for the plurality of cloud applications and/or the cloud hardware, the maintenance schedule comprising a plurality of maintenance events;
• the listener application is configured to identify an impacted cloud application of the plurality of cloud applications and/or impacted cloud hardware that is scheduled for one of the plurality of maintenance events from the maintenance schedule;
• the listener application is configured to map the impacted cloud hardware and/or the impacted cloud application to a global load balancer;
• the remediation application is configured to send a first command to the mapped global load balancer to disable traffic to the impacted cloud hardware and/or the impacted cloud application;
• the mapped global load balancer is configured to disable traffic to the impacted cloud hardware and/or the impacted cloud application;
• the remediation application is configured to execute the maintenance events on the impacted cloud hardware and/or the impacted cloud application;
• the remediation application is configured to send a second command to the global load balancer to re-enable traffic to the impacted cloud hardware and/or the impacted cloud application;
• and
• the mapped global load balancer is configured to enable traffic to the impacted cloud hardware and/or the impacted cloud application.

A non-transitory computer readable storage medium, including instructions stored thereon, which when read and executed by one or more computer processors, cause the one or more computer processors to perform steps comprising:

• receiving, from a health monitoring application for a plurality of cloud pools, a health status of a plurality of cloud applications in the plurality of cloud pools, each cloud pool hosted by cloud hardware, wherein each of the plurality of cloud pools comprises an instance of each cloud application;
• receiving a maintenance schedule for the plurality of cloud applications and/or the cloud hardware, the maintenance schedule comprising a plurality of maintenance events;
• identifying an impacted cloud application of the plurality of cloud applications and/or impacted cloud hardware that is scheduled for one of the plurality of maintenance events from the maintenance schedule;
• mapping the impacted cloud hardware and/or the impacted cloud application to a global load balancer;
• sending a first command to the mapped global load balancer to disable traffic to the impacted cloud hardware and/or the impacted cloud application;
• executing the maintenance events on the impacted cloud hardware and/or the impacted cloud application;
• and
• sending a second command to the mapped global load balancer to re-enable traffic to the impacted cloud hardware and/or the impacted cloud application.
