4-way Google Kubernetes Engine Tips for Cold Start Lag

If you use Google Kubernetes Engine for workload execution, it’s likely that you have encountered cold starts

which are delays in application launch caused by workloads assigned to nodes that haven’t hosted the workload

application code are some of the common tasks involved in deploying a containerized application on Kubernetes

The lack of a pre-existing container image on the new node might result in a much longer initial startup time The pod doesn’t need to start up again since it is already up and heated when a subsequent request comes in

When pods are being shut down and restarted repeatedly, requests are being sent to fresh, cold pods, which results in a high frequency of cold starts

Nevertheless, the warm pool technique may be quite expensive for heavier workloads like AI/ML, particularly on pricey and in-demand GPUs

The managed Kubernetes service offered by Google Cloud, Google Kubernetes Engine (GKE), may facilitate the deployment and upkeep of complex containerized workloads

Methods for overcoming the difficulty of chilly starts When using bigger boot drives or local SSDs, use ephemeral storage
