Welcome to the final installment of our series on cloud migration methods. To recap, we’ve covered the following three approaches:
Lift and Shift: Replicating all on-premise workloads and moving them into the cloud, regardless of compatibility.
Hybrid: Lifting and shifting some on-premise workloads into the cloud while keeping sensitive data in a private cloud.
Replatforming: Gradually “up-versioning” workloads to take advantage of the new cloud environment and moving it into the cloud over time.
Now, onto the final method for migration: Re-architecturing.
Re-architecturing for the Cloud Environment
Re-architecturing involves recoding and rebuilding workloads, tasks, and applications—essentially, the organization’s entire infrastructure—turning once-siloed servers and coupled applications into microservices in the cloud. In doing so, the infrastructure becomes more seamless, agile, and better able to take advantage of the new cloud environment’s scalability and elasticity. While this may sound risky on paper, re-architecturing may surprisingly be the safest strategy for moving to the cloud. After all, trying to fit a square peg in a round hole (lifting and shifting) could result in performance issues, rendering some applications useless or at the very least inefficient; on the other hand, retrofitting legacy systems (replatforming) could also be more challenging than expected, leading CIOs to ponder why they didn’t go for the full rebuild in the first place.
Factors to Consider About Re-architecturing
Despite re-architecturing being a potential low-risk strategy for cloud migration, it’s also a very time-consuming and complex task that many organizations, or their IT teams, simply aren’t prepared to tackle. But the payoff can be huge when you consider the cost implications of, for example, running a resource-intensive application that’s processing huge amounts of data inefficiently within a cloud it’s ill-suited for. In addition, the vision for the company’s future needs to be considered: are there plans to open up access to mobile devices? Re-architecturing to ensure functionality and performance may be the best bet.
Digital Decoupling as a Re-architecturing Strategy
In architecture that’s tightly-coupled, each component must be present for code to be executed. If an organization is aiming to re-architect their infrastructure, but needs to make quick moves with certain applications to stay current or competitive, they may engage in digital decoupling. This involves separating coupled architecture so that some components can be optimized and moved to the cloud, where they can now run independently on top of legacy systems. Decoupling shares some similarities with replatforming, except that the endgame is to have all assets in the cloud and 100% optimized for the new environment. This strategy allows organizations to decouple their core systems over time, migrating critical functionality and data to new platforms until eventually all assets are functioning as if they were cloud natives.
What Method Will Your Organization Choose?
There are many considerations when migrating to the cloud. Lift and shift, replatforming, re-architecturing, and taking a hybrid approach all offer distinct advantages and disadvantages—but there’s no time like the present to make the move to the cloud. Ultimately, who you choose to work with as a provider can make all the difference. A reputable provider will work with you to review the needs of your organization, and will explain your options. Then, they’ll work with you to make sure the migration is seamless—and will be there for you 24/7 to answer questions and provide support. DSM, Florida’s predictable cloud provider, has helped countless organizations in the Sunshine State, and around the country successfully transition to the cloud, and can do the same for you.
