Migration vs Rebuild


12 November 2018

Cloud Migration



Of these five options, WorkingMouse favours one in particular: the rebuild option. Our team of developers and designers create bespoke SaaS (Software as a Service) and place a strong emphasis on collaboration with our partners. If your CIO has assigned you the task of moving your business processes to the cloud, we have a guide for you in this article on how you can rebuild and migrate with WorkingMouse's support.

Before you decide whether you will be rebuilding or migrating, consider:

  1. The speed of your applications, and functionality limits;
  2. Your priorities with latest technology; and
  3. If you're using off-the-shelf software that doesn't quite fit the needs of your business.

Legacy software and old outdated operating systems are notorious for stability and reliability issues.

Rebuilding or re-architecting your applications completely rewrites existing application code. While this method inherently means you will lose the familiarity that comes with working within a particular code or framework, the benefits are numerous. By rebuilding, you have the chance to improve developer productivity by eliminating unnecessary code and simultaneously customise processes to suit your business.

By creating your own bespoke software application, you'll save money; staff training for off-the-shelf software becomes obsolete. Rebuilding applications from scratch has become much easier thanks to technological advancements and the wide range of cloud-native technologies available. For example, Azure is a Platform as a Service (PaaS) that enables companies to combine a range of applications in one custom build. This eliminates the expense and complexity of hosting software licenses for multiple applications. With bespoke software, you manage your application and services, and your chosen platform manages everything else.

If speed is your main priority, you may be tempted to migrate rather than rebuild. However the long term benefits of rebuilding outweigh the speed of migration. You can solve current administration based issues and have control over the foundations and infrastructure of your application. This will give your company a competitive advantage that allows you to start on the path of continuous modernisation.
