Decided to test a failure scenario on my home network: What if Omada Controller is unavailable?

(edit to add context: What happens when devices reboot when the controller is unavailable)

The access points require Omada Controller to function, so no wifi.

The core switch goes into "dumb switch" mode, which is good. However, it does not enable the SFP+ ports, which is bad because my router connects to one of them.

That last one is a problem because I don't use static IP configurations on anything except the router, so if a lease expires on the Omada device, none of my Omada devices can get their configuration.

So I might have to reconsider how I do static address configurations.

Chaos Engineering: Building Resilient Systems Through Failure Testing

In today’s fast-paced digital world, maintaining resilient and reliable systems is paramount. Service disruptions can lead to significant financial losses, damage to reputation, and loss of customer trust. Chaos engineering has emerged as a proactive approach to bolster system resilience by intentionally inducing failures to uncover weaknesses before they manifest in production environments. This article delves into the strategic importance of chaos engineering, how to design and execute failure scenarios, and the tools that facilitate these experiments, ultimately improving overall system robustness.
