Application modernisation is necessary so that companies can meet the current and future requirements of their business. Modern companies’ core applications have a decisive impact on how competitive they are: new opportunities on the market need to be acted on quickly, business is becoming more agile and so the software that supports this business needs to adapt as well. Outdated applications are often based on end-of-life technologies and tend to be extremely complex. As a result, they generate additional costs, pose a potential security risk due to a lack of support, and result in a competitive disadvantage over the medium term.
