In incident management, the primary goal during the "Mitigation" phase is to restore service levels as quickly as possible, often referred to as "stopping the bleeding." Google Cloud’s SRE principles emphasize that during a high-priority incident, you should prioritize actions that have an immediate impact over long-term fixes or deep-dive forensics. While a rollback (Option C) is a standard procedure, the 15-minute CI/CD overhead is too slow when a critical payment service is failing. Using Cloud Profiler (Option A) is a diagnostic step that should be reserved for the post-mortem phase, not the heat of the outage.

Canceling the active Dataflow job (Option D) is the fastest way to alleviate the pressure on the shared Memorystore instance. Since the Dataflow pipeline is "non-critical" and "batch-based," stopping it has a low business impact compared to the payment service outage. Once the job is canceled, the write pressure on Redis drops instantly, reducing read latency and restoring the payment service to health. This aligns with the SRE practice of "shedding load" to protect critical system components. Once the immediate crisis is resolved, the team can then investigate the root cause and implement long-term fixes like rate limiting or resource isolation.

Google Cloud’s Dynamic Workload Scheduler offers two distinct modes designed to balance resource availability with cost and criticality. Flex Start mode is optimized for cost-sensitive, asynchronous workloads that do not have a strict start time. It allows the scheduler to obtain capacity when it becomes available within a 7-day window, making it the ideal choice for the Research team's hundreds of small experiments. This mode prioritizes resource optimization and lower costs over immediate execution.

Conversely, Calendar mode is designed for business-critical jobs that require guaranteed capacity at a specific date and time. By using Calendar mode, the Production team can reserve the necessary GPU or TPU resources for their Friday 10:00 PM retraining session. This ensures the job starts exactly on time and runs without interruption, satisfying the "business-critical" requirement. Combining these two modes allows an organization to maximize cluster utilization: using Flex Start to fill the gaps with non-urgent research while ensuring that high-priority production tasks have the "just-in-time" resource guarantees they need to maintain SLOs (Service Level Objectives).
