This last weekend, I gave a presentation for the Global Azure Bootcamp about Application Insights. In case you were wonder what Application Insights is about, it allows components to post application telemetry back to Azure.
I have spoken about the need for applications to recover from faults. Naturally, adding network-based dependencies could negatively affect resiliency.
Application Insights does not affect the resiliency negatively!
It just happened that Application Insights failed. As in, it was down for 16 hours. However, the demo application still functioned without a glitch.
No slow-down, no error messages. In fact, the only reason why I picked up the Application Insights was down, was looking at the Azure Status page.
