Issue: Application becomes unavailable during deployments
Because Elastic Beanstalk uses a drop-in upgrade process, there might be a few seconds of downtime. Use rolling deployments to minimize the effect of deployments on your production environments.
Event: Failed to create the AWS Elastic Beanstalk application version
Your application source bundle may be too large, or you may have reached the application version limit.
Event: Update environment operation is complete, but with command timeouts. Try increasing the timeout period.
Your application may take a long time to deploy if you use configuration files that run commands on the instance, download large files, or install packages. Increase the command timeout to give your application more time to start running during deployments.
