Which architecture is better in terms of scaling, cost, and security — Kubernetes or serverless? Tolts, on the Kubernetes side, credentialed himself as a committer and maintainer for numerous large-scale applications that use Kubernetes has seen the good, bad, and once in a lifetime.
Large traffic spikes don’t affect the cost and the workload doesn’t have to be estimated or forecasted as precisely as it does with serverless as serverless costs can grow quickly.
To the cons, Tolts admitted that scaling Kubernetes was more complicated than scaling serverless but not without also adding that AWS does offer autoscaling.
Kubernetes from regular updates and serverless from the cloud provider, but there is still development work.
