<strong>How to manage EKS Pod Identities at scale using Argo CD and AWS ACK (9 minute read)</strong>
</span>
</a>
<br>
<br>
<span style="font-family: "Helvetica Neue", Helvetica, Arial, Verdana, sans-serif;">
This post demonstrates how to manage Amazon EKS Pod Identity associations at scale using Argo CD and AWS Controllers for Kubernetes (ACK) within a GitOps workflow. It addresses the challenge of the EKS Pod Identity API's eventual consistency by introducing a validation job to confirm IAM role readiness before pod deployment or by tuning the Argo CD sync wave delay, ensuring reliable and secure automated deployments.

<strong>Advancing Our Chef Infrastructure: Safety Without Disruption (9 minute read)</strong>
</span>
</a>
<br>
<br>
<span style="font-family: "Helvetica Neue", Helvetica, Arial, Verdana, sans-serif;">
Slack has enhanced its EC2 infrastructure safety by splitting its single production Chef environment into multiple isolated environments (prod-1 to prod-6) based on Availability Zones. Slack also replaced scheduled Chef runs with a new Chef Summoner service that triggers runs based on signals from Chef Librarian, ensuring updates are only applied when available, and introduced a fallback cron job to maintain compliance and recover from Chef Summoner failures. Slack is building a new EC2 ecosystem called Shipyard, which is designed for service-level deployments, metric-driven rollouts, and automated rollbacks.
