We had to draw the line for our analysis somewhere, so we took the first 700 responses and created the charts below. If there is a significant change in the number of responses, we'll update these charts with new results. We cover topics such as: which containers are most often used on large projects, to which container is the fastest, to redeploy times and annual costs of redeployment, then we provide the data for you to analyze yourself.

If you haven't stressed your application in production, then you don't know if it will really perform under load.

I was reading somewhere about some anecdotal evidence that Google doesn't like to index images that don't have some kind of modification time on them.
