Don’t “Lift and Shift”

From https://media.netflix.com/en/company-blog/completing-the-netflix-cloud-migration:

Arguably, the easiest way to move to the cloud is to forklift all of the systems, unchanged, out of the data center and drop them in AWS. But in doing so, you end up moving all the problems and limitations of the data center along with it.

Running virtual machines in AWS the same way you run virtual machines on your own VMware infrastructure isn’t a great idea.  It may be the easiest way to make the leap to the cloud, but it will likely not be the best long-term solution in terms of reliability, availability, or cost.  A better way to do it would be to re-architecture everything to run “cloud-native”, and take advantage of all the benefits of the elastic architecture and automation.  That, of course, takes a lot of work.
