Monolithic architectures have historically been challenging to scale. It becomes increasingly difficult to update and maintain an application as its code base grows. It becomes extremely difficult to introduce new features, languages, frameworks, and technologies. This limits innovation and new ideas. Developers must make large-scale changes to the entire codebase to implement new features, making the process time-consuming and complex. This can lead to bugs and security vulnerabilities. As a result, organizations are increasingly turning to microservices architectures to solve these problems.
