In the lift and shift approach, all that is really moving is the final data and reporting that come out of your applications and processes. However, without your applications themselves running on the cloud, all your team can do is access data, not create, analyze, and use it.
Application refactoring, also known as application modernization, essentially brings your applications to the cloud. This is more than a backup strategy because it enables greater flexibility and reliability. So long as you have an internet connection, you can access the tools you need to get work done. Also, because your tools are not operating locally, you are insulated from events like power outages or other, more disastrous natural events.
Application refactoring is not an all or none solution. This approach is inherently flexible in that only the applications that are necessary for your organization need to be migrated to your cloud-based infrastructure. Additionally, your legacy applications can continue to operate on your local systems while the migration process is underway. In other words, you don’t need to worry about the process disrupting your operations.
