In the ever-evolving world of technology, application refactoring has become a critical process for businesses. Legacy applications often underpin essential everyday operations, yet because they have traditional and often inflexible architectures, they can hinder a business’s ability to remain flexible, adaptable and agile in the modern cloud-based landscape. Almost all businesses are now using the cloud in some capacity or another, and ensuring all critical applications are optimised to allow for full integration with other services has become key to ensuring business continuity.
Legacy applications are pieces of software which, despite having out of support components, continue to operate and fulfil their intended purpose. These applications have often served businesses well and faithfully for years, but continued reliance on outdated applications while modernisation is happening in other areas of the ecosystem can pose significant risks for businesses.
Chief among the risks is the lack of support and fixes for legacy applications from vendors. If a critical patch were to be released by a vendor, and a business implemented it on an out-of-support application, the patch could cause a failure of the application and put a halt to the operations it supports. In this respect, modernisation of legacy systems is not simply about ensuring businesses can remain responsive; legacy applications can pose a serious threat to business continuity.
To mitigate the risks associated with unsupported software, refactoring legacy applications is essential. Refactoring involves restructuring and optimising an application’s code to meet the standards and demands of modern business and migrating to a more modern tech stack to allow for full integration with cloud-based applications and systems.
There are a few options for businesses when it comes to how apps will be modernised:
Each of these processes comes with its own challenges, and certainly the time, resources and cost required to modernise legacy applications can make businesses hesitant. But it’s important for businesses to weigh up the benefits and potential risks of maintaining legacy applications – in most cases, refactoring is a worthwhile investment.
The potential consequences of an application that supports mission-critical processes breaking means assured business continuity is one of the primary benefits of application refactoring. But there are other benefits that mean application refactoring makes good business sense:
Refactoring legacy applications for modern technology stacks and migrating them to the cloud can be both complex and time-consuming. Legacy applications have often been subject to ad hoc patches and modifications over many years, and they can underpin workflows that aren’t immediately obvious, and which have never been documented. In many cases, it will be crucial for businesses to roadmap their refactoring, and to collaborate with migration specialists to ensure all critical processes and workflows are accounted for. At BCN, for example, our expert developers are Microsoft certified to ensure legacy .net applications are migrated fully to the latest framework to ensure longevity and give businesses access to ongoing support for years to come.
Refactoring legacy systems is a vital step for businesses looking to ensure business continuity, improve systems efficiency and remain agile and responsive in a tech landscape that is evolving at lightning speed. By partnering with the right experts and creating a solid migration plan, businesses can embark on a transformative journey that secures their applications’ longevity and unlocks new opportunities for growth.
