How To Bring Your Legacy Apps Into The 21st Century
Digital transformation might be one of the biggest business trends – but that doesn’t mean it’s just a buzzword. Over the last ten years, updating legacy apps has emerged as a top priority for companies worldwide. As we become increasingly well-connected, businesses with outdated systems can easily lag behind their more tech-savvy competitors. But what’s the best way to bring your legacy apps into the 21st century?
Why Update Your Legacy Apps?
There are a number of reasons why you should consider updating your legacy apps. From inefficiency to unsustainability, old systems can be plagued with problems that will cost your business valuable time and money.
- Legacy apps can seem unintuitive to younger employees who have grown up with technology. This can make it harder to attract new talent.
- Legacy apps are often harder to back up, leaving your data at risk.
- Legacy apps can be expensive to run (and to troubleshoot).
How To Update Your Legacy Apps
To find the most suitable approach for your business, you’ll need to consider the following questions.
Rebuilding or Re-platforming?
As its name suggests, rebuilding your legacy apps means that you (or your developer) will need to start them again from scratch. This might sound extreme, but if your programs aren’t fit for your customers today, it could be the most sensible option.
On the other hand, re-platforming is the process of migrating your apps and data to a new platform (without rebuilding them first). Many businesses choose to migrate their apps to the cloud.
Refactoring or Re-architecture?
Refactoring refers to the act of restructuring your existing codebase in a way that makes your apps more sustainable without changing their behaviour. Re-architecture is the process of altering your apps materially to move them onto a different platform, such as the cloud.
The right strategy for you will depend on the nature of your legacy apps. If they function perfectly well but aren’t sustainable in their current form, refactoring can enable you to migrate your apps without losing any of their current functionality. If they aren’t working as well as they should (for example, if they aren’t optimised for mobile, load slowly, or crash frequently), then re-architecture will enable you to solve these issues whilst transferring them onto a better platform.
Benefits Of Cloud Migration
Cloud migration is one of the most popular methods of updating legacy apps. Storing your apps will protect your data from accidental loss and can be significantly cheaper to run than an alternative, licensed platform.
Apps hosted in the cloud can also be more accessible, both to your end–users and any developers who will update your apps in the future.
