Migrate your workloads to the cloud
Preparing to Move
Conclusions
Whether you can allow yourself the luxury of rewriting an application for the cloud or need to migrate existing workloads to the cloud, most environments operate well in clouds. If you want perfect "cloud readiness," you will rarely be able to avoid rewriting the application. However, you can create a new application according to the latest standards that fits the cloud like a glove.
Even if you can't do that, you still have no reason to panic: Conventional applications will run well in clouds with a few tricks. However, admins must view the cloud as an ally and not as an enemy that needs the most efficient workaround that can be found.
Even if you end up running legacy workloads, you shouldn't ignore the various modern features of the target cloud – on the contrary, it's better to employ them actively.
