Have you thought about moving your IT infrastructure to the cloud, but are unsure of which migration strategy would best match your business needs? Well, you have landed on the right blog. In this series we will discuss each type of cloud migration. Today, we’re starting with the Lift & Shift approach.
What is the Lift & Shift Approach?
Lift and shift (also known as Rehosting) is the strategy of migrating legacy applications that are hosted in an on-premises environment directly to the cloud without redesigning. The goal is to move the application “as is” with little or no changes.
Whether organizations migrate to the cloud from an in-house environment or one cloud to another, migrating can be a complicated process which requires careful planning and contemplation. It’s essential for organizations to consider the pros and cons before zeroing in on any one migration strategy. Here are some of the advantages and disadvantages of the lift & shift approach:
Less Time-Consuming – If a business requires faster cloud migration then the lift & shift approach is one of the quickest. It takes everything from the server and copies it to the cloud as-is, whereas other cloud migration strategies are time-consuming and might require IT experts. Lift & shift makes the migration process easy and fast.
Easy Handling – As this approach requires no re-designing and is replicated piece by piece, the lift & shift approach is easy to handle. Other cloud migration strategies need consistent technical support.
Less Resource Intensive – It requires less human-effort as compared to other migration strategies because of its natural process.
Lack of Accessibility – Lift & shift is a process of migrating apps to the cloud as-is, and some applications might not be able to leverage the full potential of cloud infrastructure. Only those applications that are cloud-native can fully take advantage of cloud computing.
Lack of Compatibility – Applications that rely heavily on third-party software might not be compatible with the cloud, and are therefore not a good fit. It’s advisable to check for compatibility ahead of time to avoid setbacks.
A successful migration should address both long and short-term business goals, such as decreasing hosting costs and creating a better alignment between IT and business objectives. Lift & shift is a simple, direct, and cost effective approach.
