A:

In light of recent, multi-regional connectivity disruptions, such as the July 2024 issue impacting Google Cloud Networking, runbooks for Google Cloud Platform (GCP) must shift from reactive, single-failure responses toward proactive detection and multi-layered, hybrid failover strategies. A passive approach assuming regional isolation is no longer sufficient.

A:

To proactively spot latency spikes on Google Cloud before customers do, SREs should use a multi-layered approach, creating custom dashboards in Cloud Monitoring that combine platform-wide network intelligence with deep, service-specific metrics. Early warnings can come from either a degradation of the underlying network or from saturation in a specific application service.

  • Layer 1: Network Intelligence Center

The Google Cloud Performance Dashboard provides a high-level view of network health. It's the first place to look for signs of a broader network issue, which can often precede application-level problems. 

  • Layer 2: Application-layer observability

Custom dashboards in Cloud Monitoring should be configured to capture fine-grained metrics for your specific workloads. This provides early warnings of application-level saturation that can cause user-facing latency.

  • Layer 3: Tracing and logging

For deeper analysis during an incident, integrate and analyze data from Cloud Trace and Cloud Logging.

A:

Following recent incidents affecting cloud providers, including Google Cloud (GCP) networking issues, disaster recovery (DR) testing for critical GCP services must evolve to simulate complex, multi-layered failures. Testing should focus on validating cross-regional failover, application resilience during partial degradation, and hybrid cloud strategies, moving beyond simple single-zone outage scenarios.

  • Validate cross-regional failover (Game Day)
  • Verify application behavior during partial degradation
  • Conduct multi-cloud or hybrid failover testing
  • Practice communication and documentation

A:

For Google Cloud, protecting workloads from regional cable cuts relies on a combination of multi-regional load balancing and intelligent DNS routing policies. By distributing resources and leveraging Google's global network, workloads can automatically shift traffic away from an affected region with minimal disruption.
