In modern software development, it is crucial that companies implement robust and scalable software architectures. However, many companies are faced with the challenge of modernizing existing systems or designing new architectures that must meet both current and future requirements and provide the basis for long-term sustainable IT solutions. In principle, there are many possible solutions for individual challenges, but not all of them are suitable for your own context. It happens to the best teams that important requirements are overlooked. The consequences can be inefficient processes, security gaps, increased costs and, in the worst case, even the failure of entire IT projects.
