Network Outage for Kubernetes Nodes in an Availability Zone
Achieve high availability of your Kubernetes cluster via redundancy across different Availability Zones. Check what happens to your Kubernetes cluster when one of the zones is down.
Motivation
Cloud providers host your deployments and services across multiple locations worldwide. From a reliability standpoint, regions and availability zones are most interesting. While the former refers to separate geographic areas spread worldwide, the latter refers to an isolated location within a region. For most use cases, applying deployments across availability zones is sufficient. Given that failures may happen at this level quite frequently, you should verify that your applications are still working in case of an outage.
Structure
We leverage the block traffic attack to simulate a full network loss in an availability zone. While the zone outage happens, we observe changes in the Kubernetes cluster with Steadybit's built-in visibility. Once the zone outage is over, we expect that all deployments will recover again within a specified time.
