AWS Outage and Hale Stack

How Hale Stack Delivered Zero Downtime During the AWS Outage

When AWS experienced its latest major service outage, many companies faced downtime, data unavailability, and disrupted customer experiences. But not Hale Stack customers.

Thanks to Hale Stack’s multi-cloud failover architecture, every client application automatically shifted from AWS to Google Cloud Compute (GCP) within seconds, without losing a single transaction or user connection.

Resilience by Design

At Hale Stack, we believe uptime is not an afterthought. Uptime is a core engineering principle. Our infrastructure was designed to operate across multiple cloud providers, ensuring high availability and continuous service delivery even during catastrophic regional failures.

The secret lies in intelligent failover abstraction and real-time replication between AWS and Google Cloud. These services exist in our own proprietary data centers stregically located around the world.

How the Automatic Failover Works

1. Synchronized Data Layer

   • Data is continuously replicated between AWS RDS (or DynamoDB) and Google Cloud SQL (or Firestore) using asynchronous streaming pipelines.

   • Replication lag is monitored to ensure data consistency.

2. Load Balancer Health Checks

   • Global traffic is routed through Hale Stack’s Anycast-based DNS and global load balancer.

   • Every 10 seconds, health checks confirm that AWS endpoints are healthy.

   • If an AWS region or service becomes unavailable, traffic automatically reroutes to the corresponding GCP instance group.

3. Orchestrated Compute Failover

   • Containerized workloads (via Kubernetes) are mirrored across both AWS EKS and GCP GKE clusters.

   • During the AWS outage, workloads were seamlessly promoted on GCP using the same container images and infrastructure-as-code templates.

4. Automatic Recovery

   • Once AWS services stabilized, synchronization processes reversed — restoring AWS as the primary environment while maintaining GCP as hot standby or vice versa.

Zero Downtime. Maximum Trust.

During the AWS downtime event, Hale Stack’s monitoring dashboard showed 0% downtime across all managed customers.User requests were automatically rerouted to Google Cloud, and system performance metrics remained within 3% of baseline levels — a testament to the strength of true multi-cloud engineering.

“Our customers didn’t even notice AWS was down,” said Aaron Hale, Founder of Hale Stack. “That’s exactly how it should be.”

Key Takeaways

• Automatic Failover: Instantaneous switch between AWS and GCP.

• Data Consistency: Continuous replication ensures zero data loss.

• Multi-Cloud Architecture: Prevents vendor lock-in and maximizes resilience.

• Customer Confidence: Hale Stack clients stayed online while competitors went dark.

Looking Ahead

Hale Stack continues to expand its multi-cloud orchestration platform, adding support for Azure failover, edge deployments, and AI-based predictive scaling. We have also began the process for incorporating Yandex Cloud, Alibaba Cloud, and Baidu.
