On-premises (or “shrinkwrap”) software is old news. An estimated 85 percent of American enterprises have a multi-cloud strategy in 2017, up from 82 percent in 2016. Among the minority of businesses that fail to leverage cloud technology, lack of resources and security are cited the biggest concern for why they haven’t migrated yet.
To unlock the many benefits hybrid and full cloud solutions can offer, businesses must ultimately overcome these technology challenges in order to stay competitive in an increasingly cloud-driven world. Partner with Ad Victoriam Solutions, an experienced cloud migration consulting company, to learn how to leverage cloud solutions to work for you - not the other way around.
We have the knowledge and experience to answer tough questions from CIOs and IT managers, such as:
Every business is unique - which means a cloud migration strategy that worked for another organization may not work for yours.
So, what cloud migration model is right for your business?
There are 5 main options for migrating your applications to the cloud - listed in order based on how much you want to leverage existing applications (most to least):
Also known as “lift and shift,” this approach involves redeploying your existing hardware onto a cloud platform and restructuring the original configuration of all your applications (Infrastructure-as-a-Service). The upside of lift-and-shift is it can accomplish system modernization quickly and efficiently with minimal effort. The downside is the full benefits of the native cloud application can be lost or reduced, and it can cost more to operate the application in a cloud environment.
Application refactoring refers to running your Web applications (AWS, Azure, etc.) on a cloud server. Developers must often configure and change code structures to connect existing applications to the cloud. Refactoring benefits a business by allowing developers to leverage existing languages, containers and frameworks, making this one of the most cost efficient migration methods. A potential disadvantage of this approach, however, is weak or missing PaaS (Platform-as-a-Service) capabilities.
The revised approach is when an application’s current code is modified or extended to support legacy systems modernization, then the application is deployed to the cloud via the rehosting or refactoring option. This is an effective option by allowing developers to leverage valuable codebase and meet migration goals. However, the revising option can require significant upfront investment to secure a team of skilled developers and, depending on the scale of the migration, may take the longest time to deliver full capabilities.
Taking this approach means developers must reconstruct an existing application’s container to function in the new cloud environment and discard the old code. The pros include improved developer productivity due to customizeable application templates, data-powered engines and numerous developer communities that provide pre-build components. Automation of scalability and provider-managed updates are also advantages of the rebuild approach. On the downside, data lock-in and PaaS immaturity are the main challenges.
Completely discarding your existing application/s and using commercial SaaS (Software-as-a-Service) solutions instead is known as the replacement approach. The benefits of starting from scratch with the replacement method is the ability to simplify and consolidate applications and data under one “umbrella” infrastructure. Downsides include the risk of data lock-in, incompatibility and difficulty customizing or reconfiguring applications - all of which can increase developer time and migration costs.
