Rehost vs Replatform: Choosing the Right Cloud Migration Strategy

No longer are companies choosing to build out their own infrastructure. In fact, most are doing the opposite – exiting their data centers either completely or partially, reducing their resource overhead and CapEx expenditures.
Today, companies are opting to put most, if not all of their new “workloads” and high-value business applications in the cloud. This digital transformation is really unburdening companies of their on-premise footprint and making it quicker and easier for them to deploy technology that makes their business more agile and more competitive.
In basic terms, a data center exit (data center decommissioning) just means removing the cost of leasing the space, paying the utility bills and maintaining the equipment in one or more data centers from your IT spend.
You may think that data center decommissioning is synonymous with adopting a more “cloud-centric” approach to IT modernization. This is not a hard and fast rule, as there are some compelling events that may favor a data center exit irrespective of your cloud-adoption strategy.
Here are two examples:
You may have recently acquired a company including their technology and their employees and are now ready to enjoy the benefits that this will bring to your organization. With this comes all the infrastructure to support the acquired organization. There will undoubtedly be a big overlap in the utility infrastructure supporting corporate collaboration and productivity, which is typically the first target for consolidation. You may have been going through M&A activities for years and putting off the consolidation work. Either way, companies will need to address this to ensure a better return on investment (ROI) from these events and taking an expensive data center spend off your IT budget is a great way to realize that return.
As your company has grown, so have your points of presence and that may have previously necessitated the need for building out regional data centers to align with business needs. As these leases come up for renewal, it makes sense to re-evaluate your IT-sprawl and decide what works best – newer technology today means higher density compute and storage devices. Maybe the costs of real estate and electricity have shifted geographically. Your data center decommissioning plan should evaluate these factors and allow you to focus on maintaining the data centers that provide the most cost-effective and secure solution for your company.
The majority of the hardware that exists in your data center is nearing its end of life, or maybe on extended support contracts – all of which is becoming more expensive to maintain year after year. Replacing this equipment in full is not feasible, so decommissioning and consolidation will serve your organization better.
With these things being said – a data center exit strategy will include a cloud migration strategy aligned with your IT modernization program.
The question isn’t
“Should I migrate to the cloud?”
It is
“What should I migrate to the cloud and when?”
This is not an all-or-nothing proposition, almost all organizations are using the cloud today – in fact, you’d be challenged to find one that isn’t - whether it is for specialized SaaS applications, general productivity, or collaboration. The decision is finding the workloads that should be migrated to the cloud to give your company the best cost structure, most flexibility and competitive advantage.
Why should I migrate to the cloud? What do I gain from leveraging cloud-based services?
There are so many reasons companies are opting to leave the traditional data center model and migrate those workloads to the cloud.
We’ve discussed a bit about the golden age of the corporate private data center, the reasons why you may need to plan a data center exit and some of the benefits organizations see when adopting cloud technologies.
Next, let’s focus on some of the challenges that may arise during any IT modernization project.
Careful planning and preparation can typically be measured in years, necessitating a thorough evaluation of your data center decommissioning strategy and journey to the cloud.
For all applications and data that will remain on-premise (but consolidated into a different data center), re-homing them will require application and data migration planning – or you may choose to go the low-tech route: box up all your gear and have it delivered via a white-glove service to your target datacenter. Of course, this assumes your equipment is worth the move, and will survive the transport!
For all applications that are migrating to the cloud, Gartner published a paper in 2011 identifying the “5 Rs” of cloud migration techniques: Originally referred to as Rehost, Refactor, Revise, Rebuild and Replace – while the concepts remain the same, the actual Rs may have changed a bit over the years. Ultimately, each application will be analyzed to determine how to best handle its transition to the cloud, with IaaS, PaaS, or SaaS typically being employed.
We've got more information on the 5 Rs in this blog post.
Not all applications are candidates for cloud migration – there needs to be a cost-benefit to make it viable, some will remain on-premise for the foreseeable future.
If you want to know about how to successfully migrate legacy data, take a look at this blog post.
Savvy customers of yours will want to know that you are doing everything possible to ensure that their data and PII (personally identifiable information), is just as safe and impervious to theft as it travels throughout your new “cloud-based” infrastructure. This necessitates ensuring all the policies and controls are in-place and you are able to provide documentation of those controls. Third party audits, PEN tests, vendor assessments and cloud evaluations are all part of the game.
Exiting a data center is part of a normal business cycle. Many customers are trying to rationalize their IT spend, better use their resources and look for ways to be more agile and prepared for the future. Your project may be as simple as consolidating user data from one data center to another, retiring some legacy applications and hardware, but oftentimes it will be more complex – requiring a blend of consolidation, cloud migrations, data migrations, application rationalization, and all the services that go along with it.
