⚡ Lightning Talk: Is Everyone O-KEDA? “Exciting” Lessons Learned in Our Journey to Use KEDA Pod Autoscaling - Brian Davis, Red Canary

Tuesday November 12, 2024 5:55pm - 6:00pm MST

Hyatt Regency | Level 4 | Regency Ballroom B

We thought that changing our Kubernetes pod autoscaler seemed like a really straightforward thing to do. With relative ease, we yanked out our old custom pod autoscaler and replaced it with KEDA. We were impressed with the flexibility and control we now had in our cluster, but then discovered a set of really hard lessons that no one had anticipated. In this lightning talk, I’ll hit the highlights of secondary issues we encountered due to such a seemingly simple change, such as Docker Hub rate limits, Kubernetes metrics server failures and their exciting impact on our cluster, AWS rate limits, and late night fights with Argo CD for control of pod maximums. Lastly, I’ll share my personal favorite topic: the “Night Club Theory” of autoscaling tuning. If you or someone you love is thinking of changing your autoscaler, I recommend spending 5 minutes with me to learn the things you should be aware of before you make the switch!

⚡ Lightning Talk: Minimizing Data Loss Within the OpenTelemetry (OTel) Collector - Alex Kats, Capital One

Tuesday November 12, 2024 6:00pm - 6:05pm MST

Hyatt Regency | Level 4 | Regency Ballroom B

The OTel collector is meant to serve as a reliable and highly performant data pipeline. However, as a single component in a wider observability architecture, it is only as reliable as the downstream platforms/services it exports data to. The OTel collector has several built in mechanisms that aim to minimize the impact of unhealthy downstream exporters, including an out of the box sending queue with an additional configuration parameter for persistent queueing. There is a new component in the OTel contrib distribution, the Failover Connector. The Failover Connector allows for dynamic routing or “failover” of telemetry data based on downstream exporter health. This provides significant improvement to the data resiliency of the collector, as telemetry data can be continuously exported to a set of stable secondary locations, while the issues with the primary are resolved.

⚡ Lightning Talk: Safer Cluster Upgrades with Mixed Version Proxy - Richa Banker, Google

Tuesday November 12, 2024 6:10pm - 6:15pm MST

Hyatt Regency | Level 4 | Regency Ballroom B

Upgrading Kubernetes clusters often presents numerous challenges, including potential downtime, compatibility issues, and the complexity of managing multiple versions. The Mixed Version Proxy feature introduced in Kubernetes 1.28 aims to mitigate these challenges. This talk will delve into the technical intricacies of the Mixed Version Proxy, exploring its design and implementation. We will then highlight the substantial benefits it offers for cluster upgrades, such as minimizing downtime and enhancing overall reliability. Attendees will gain practical knowledge through (possibly a demonstration) on enabling and utilizing the Mixed Version Proxy. Finally, we will provide insights into the future roadmap for this feature, including upcoming beta releases and enhancements.
