What is lift and shift cloud? You might consider moving your data and applications into the cloud using lift and shift. Lift and shift move an existing application or data from a local server to a cloud infrastructure without redesigning or modifications. This usually means moving to public cloud providers like Amazon Web Services or Microsoft Azure.
Cloud computing is a paradigm shift in the technology world. Cloud computing is a paradigm shift in technology.
When you take a closer look, it’s different than the decision to migrate your data to the cloud, which will save you money and time. It’s not what you do but how you do it.
You must understand all the options available to get the maximum return on investment from cloud computing. Otherwise, you will use the same infrastructure on another person’s computer. It’s called a “lift and shift” migration or simply replicating your existing applications in the cloud.
Companies that have refactored and decoupled their systems to use the cloud effectively have seen millions of dollars saved in computing costs and increased product innovation. This is because employees think and operate with a cloud-first mindset.
Companies can reap the benefits of iterative migration quickly, even though reaching this level can take many years.
When is it a good idea to use the lift-and-shift model
Lift and shift are also known as rehosting. Rehosting a legacy application into a cloud infrastructure can be the best option for some applications. If your legacy application is currently in a virtualized environment, move it into a cloud infrastructure that closely resembles its current infrastructure.
A lift-and-shift approach is the best way to save money in this situation. By replicating your application, you can reap the benefits of auto-scaling, pay-per-usage, and other cloud features.
This is the first approach many businesses take when they do not have enough engineers who can work in a cloud-first environment. It is not necessary to have a deep understanding of cloud technology to replicate an existing application.
Some workloads are not refactorable, either because the software is third-party or it’s not in the business’s best interest to rewrite them. These workloads are doomed if they move to the cloud.
There are drawbacks to a Lift and Shift migration. This is often a way to shift expenditures from CapEx into OpEx. Sometimes leaders are left looking at their cloud bill skeptically, feeling that they were sold a dream that is not their reality.
What other approaches can you take to cloud migration
This industry coined “The 6 Rs” of cloud migration to describe the various ways to consider moving legacy applications to the cloud. It is helpful when deciding which applications to move, since most companies do not migrate everything at once.
The Rs of Cloud migration
Rehost This is the same as “lift and move.”
Replatforming: Minor changes in the architecture of the applications are required to move them into the cloud. It is very close to rehosting. Just minor code updates are needed to make it work in a cloud-based environment.
Repurchase (aka replace):When cost or other logistical issues such as feature decay make migration difficult. In these cases, it may be necessary to procure a third-party solution and acquire a software-as-a-service solution. Cloud-first ecosystems have helped small businesses grow quickly.
Refactoring (also known as Rearchitecting).If there are new requirements for scale, speed of market or other considerations, it can be beneficial to rewrite large portions of an application. Refactoring/rearchitecting is the most complex of the 6 Rs, but it also has the highest opportunity for optimization.
Retired: When an enterprise becomes more agile, and goes through a digital transformation in which the legacy application gets replaced by a newer one. Imagine that you have an application built 10 years ago. Since then, many procedural changes took place. It is better to replace the old software with a new one.
Retain It may be beneficial to re-prioritize migrations of applications based on the business requirements and urgency. You can retain something to revisit at a future date.
What is the best migration strategy for me
A Cloud Guru offers courses that walk you through the cloud migration step-by-step. Do not be intimidated by the fervor of cloud experts who boast about their micro-services and refactoring efforts. It is important to get quick wins, practical experience and hands-on training.
