Difficulties with debugging and monitoring

There is complexity in debugging distributed systems using serverless architecture. When multiple functions integrate with each other to perform a task and something goes wrong, it can be difficult to understand when and why the problem occurred. Vendors provide tools for debugging and monitoring, but there is still a level of immaturity with the serverless architecture pattern. Serverless architecture applications will become more prevalent, but it is still relatively new compared to other types of software architecture.
