Benefits of Lift and Shift Migration
The lift and shift method, also known as rehosting, offers several advantages for businesses looking to migrate their data centers to the cloud.
Cost Savings: One of the biggest perks is the immediate cost savings. By moving to the cloud, companies can eliminate the need for physical hardware and its associated maintenance costs. According to Cyber Command, the pay-as-you-go model of cloud services ensures you only pay for what you use, making budget management easier.
Speed: Lift and shift is quick. Since you’re moving applications as they are, there’s no need for extensive redesign or coding. This means less downtime and a faster migration process. As mentioned in the research, this approach ensures your apps remain accessible during the transition, minimizing disruption.
Simplicity: The process is straightforward. You “lift” your existing applications and data from your on-premises setup and “shift” them to the cloud. There’s no need for complex rearchitecting, making it a simpler option for businesses without extensive cloud expertise.
Reduced Labor: Because you’re not redesigning your apps, you need fewer specialized skills. This can significantly reduce labor costs and make the migration process more manageable for your team.
Risks and Challenges
While the lift and shift method has many benefits, it also comes with its own set of challenges.
Security Risks: Moving applications “as is” can carry over any existing vulnerabilities. If these weaknesses aren’t addressed before migration, they could become significant security risks in the cloud. Research highlights that unexamined faults can wreak more havoc in a cloud environment than in an isolated on-premises setting.
Performance Issues: Legacy applications might not perform well in a new cloud environment. The research notes that some applications, especially those heavily customized while on-premises, can suffer from latency and performance issues post-migration. This could require after-the-fact tweaks, adding to the overall time and cost.
Unpredictable Costs: Although the initial migration might be cost-effective, ongoing expenses can be unpredictable. The shift from capital expenditure (CapEx) to operating expenditure (OpEx) can lead to higher-than-expected monthly bills. This is often due to a lack of optimization and the need for additional changes post-migration, as noted by Forbes.
In summary, while the lift and shift approach can be a quick and cost-effective way to migrate to the cloud, be aware of the potential risks and challenges. Proper planning and thorough assessment can help mitigate these issues and ensure a smoother transition.
Next, we’ll dive into the Key Steps in Lift and Shift Migration, covering planning, assessment, execution, and optimization.
