How can I prevent Celery tasks from being lost during ECS deployments and scaling?
I'm running Celery workers on AWS ECS and want to make sure queued work is completed reliably during production deployments, autoscaling, and task shutdowns. What Celery settings and…
Can a system serving 1 million users scale to 10 million with autoscaling alone?
Suppose a codebase already handles about 1 million daily users and 300,000 concurrent users comfortably. If the target increases to 10 million daily users and 3 million concurrent…
How should I approach Kubernetes rightsizing and autoscaling safely?
I manage a relatively small Kubernetes environment with roughly 400 pods across two environments. We're starting an effort to rightsize applications and introduce HPA, KEDA, and affinity rules.…

How can I ensure some pods are always on separate nodes without breaking the autoscaling?
Hey everyone! I've been digging into how to manage pod deployments, but no luck so far and I could really use some help. I'm trying to find a…
Does KEDA really help save costs in production environments?
I'm considering implementing KEDA for event-driven scaling to reduce idle pod expenses. If you've deployed it in a real production setup, did you notice any significant cost savings,…
How to Optimize Node Resource Usage for Imbalanced Workloads in GKE?
I've been working with workloads in Google Kubernetes Engine (GKE) where the resource utilization is somewhat optimized, particularly using the Vertical Pod Autoscaler (VPA) and Pod Disruption Budgets…
