Join Brian Eiler for an in-depth discussion in this video Deployment options: Rolling, part of Amazon Web Services: Implementing and Troubleshooting PaaS Products.
- [Instructor] To help avoid some of the downtime…associated with new application deployment,…there's another option that we call the rolling update.…In a rolling update, we're going to deploy…a new version to all of the instances,…but we're going to do it in batches.…Now, you'll define the batch either by…a percentage of instances or even by just…a fixed number of instances.…The big advantage here is that from your user's perspective…there is zero down time to the application.…There is also no need to make changes to DNS…and the health checks will all continue to pass…and things will work.…
The down sides are, however, that if one batch…of the updates fail, the instances could have…different versions when you're done.…The other major consideration is that capacity issues…might result, in other words,…you're going to take perhaps half of your instances offline,…perform an update, and bring them back on…and then do the other half later.…If your application cannot run on 50% of the load,…this could present a problem for you.…
