Cloud Application Migration Strategies The 6 Rs

Cloud Application Migration Strategies The 6 Rs

As I looked at the lineup of speakers for AWS re:Invent, I took the time to read more about them. When I came across a blog post by?Stephen Orban?Head of Enterprise Strategy at AWS Considering a Mass Migration to the?Cloud??In this blog post, I really liked the way he explained the different Cloud Application Migration Strategies “The 6 Rs”.

Applications can be migrated to the cloud in a number of different ways, and, as with the ?Migration Process,? there can be many shades of gray; but we find these 6 Cloud Application Migration Strategies (approaches) to be the most common:

Rehosting (otherwise known as ?lift-and-shift?)

Replatforming (I sometimes call this ?lift-tinker-and-shift?)

Repurchasing (migrate to a different product/license, often SaaS)

Refactoring (re-architect or re-imagine leveraging cloud-native capabilities)

Retire (get rid of)

Retain (do nothing, usually ?revisit later?). (Note: These strategies build upon the 5 R?s that Gartner outlined here in 2011.)

I would encourage you to read the original post.?Considering a Mass Migration to the?Cloud?

At the End of his blog were some great additional Cloud Application Migration Strategy best Practices references, which he promises to add too over time.

One thought on “Cloud Application Migration Strategies The 6 Rs

  1. Realy nice overview. Only thing I miss is that with repurchase and refactor you may have to do a data migration (depending on the situation).

    Also, when you talk about cloud is that (only) public cloud or also private or hybrid. As in my experience one of the questions you need to ask yourself, where am I going to run it. And in a multi cloud world that could be many different places, including your own environment.
