Container Cluster Blue-Green Update for Periodic Execution Consistency

The patent applies preliminary action by configuring the load balancer with distinct communication control policies before the update execution. The standby application is pre-configured with a policy that prohibits simultaneous execution with periodic applications, preventing the consistency issue before it can occur during the blue-green update process.

The patent applies local quality by creating differentiated communication control policies tailored to specific application types. Instead of a uniform update approach, the load balancer applies specialized policies: one for standby applications that prevents simultaneous periodic execution, and another for periodic applications that ensures proper timing control, thereby maintaining processing consistency during rapid updates.

The load balancer is pre-configured with communication control policies that ensure periodic applications maintain consistent execution intervals even during blue-green updates. This preliminary configuration prevents inaccurate statistical information collection by guaranteeing proper timing control before the update begins.

The patent implements application-specific communication control policies in the load balancer that preserve measurement precision for periodic applications while allowing efficient resource utilization. The policy specifically addresses periodic applications by controlling their execution timing to maintain consistent collection intervals for accurate statistical information.
