Chaos engineering is a proactive approach to enhancing system resilience by deliberately introducing failures in controlled environments, particularly within cloud-based distributed systems. By testing systems under real-world conditions, organizations can identify vulnerabilities and improve fault tolerance, ensuring a robust response to unexpected events. Google Cloud offers tools and resources, including the Chaos Toolkit, to assist teams in implementing chaos engineering practices effectively.

Zone redundancy is now enabled by default for all Azure Container Registry (ACR) SKUs in regions that support Availability Zones, enhancing the resiliency of container artifacts without any additional cost or configuration required from users. This automatic upgrade protects against single-zone outages and applies to both new and existing registries. The Azure portal and CLI may not yet reflect this change accurately, but it is actively being addressed by Microsoft.
