Cloud Migration – Enterprises typically begin to contemplate how to migrate an application during the second phase of the “Migration Process” — Portfolio Discovery and Planning. This is when they determine what’s in their environment, what are the interdependencies, what’s going to be easy to migrate and what’s going to be hard to migrate, and how they’ll migrate each application.
Using this knowledge, organizations can outline a plan (which should be considered subject to change as they progress through their migration and learn) on how they’ll approach migrating each of the applications in their portfolio and in what order.
The complexity of migrating existing applications varies, depending on the architecture and existing licensing arrangements. If I think about the universe of applications to migrate on a spectrum of complexity, I’d put a virtualized, service-oriented architecture on the low-complexity end of the spectrum, and a monolithic mainframe at the high-complexity end of the spectrum.
I suggest starting with something on the low-complexity end of the spectrum for the obvious reason that it will be easier to complete — which will give you some immediate positive reinforcement or “quick wins” as you learn.
The 6 most common application migration strategies we see are:
It is essential to devise a detailed strategy before migrating your business operations to the cloud. That strategy starts with deciding what to do with your current on-prem applications. It will require an in-depth understanding of your existing business challenges and future goals because not every application will need to be migrated. It depends entirely on the vision set forth by your company and what you hope to accomplish by moving to the cloud.
A common mistake when moving to the cloud (and implementing any organizational change) is discussing the upcoming changes with your employees. They are the ones who can tell you which applications you NEED to migrate to the cloud. Just because your organization is paying for something does not mean that your employees are fully utilizing it. Chances are some applications are not being used at all, and your employees will be able to tell which ones they are and why.
After deciding on your goals and which applications will need to be migrated, the next step is to figure out your why. Your reason for moving to the cloud is important because that ultimately supports and defines your overall strategy. Are you merely migrating because everyone else is telling you it’s the right thing to do? Are you trying to follow in the footsteps of your competitors?
There should be a good reason your company is moving to the cloud, and you should be able to answer why now is the right time to do so.
Choosing a partner to work with on your journey to the cloud can provide invaluable help. Businesses can accelerate their migration and time to results through a strategic partnership. A partner can also help by offering:
A simple lift and shift is the easiest and most common way to overspend in the cloud. The concept of just taking every on-prem application and moving them all to the cloud will not leave your infrastructure optimized. Not every application needs to live on the cloud, and, more often than not, choosing to lift and optimize your cloud infrastructure is a much more efficient way to tackle your migration.
Establish a strategy to obtain the maximum benefits of cloud adoption by tracking the fast-changing standards evolving for cloud computing. Before beginning your cloud journey, do the math and compare cloud computing expenses against in-house IT expenses.
Cloud migration is a complex process, and so are the costs. Determining your move’s cost and benefits requires a strategic, holistic approach, so it’s essential to understand and account for all of the factors that go into a migration.
While cloud pricing used to be overly complicated, cloud infrastructure providers have simplified their pricing structures so potential customers can more easily understand them. There are many cloud cost calculators available to give you an idea of what your cloud infrastructure costs may be, regardless of whether you’ve selected a cloud provider yet.
There’s never a time when keeping your data secure shouldn’t be a top priority, even when migrating resources to the cloud. Do not assume that the cloud environment you’re moving your data to will automatically be secure. Although there are several policies and services in place to protect your data, the cloud is still less secure than on-prem. Therefore your company information will be more susceptible to hacks and security breaches.
