By design, the industry always feels it's too difficult to design distributed enterprise applications. With the fundamental concepts of a loosely coupled system, the lack of latest current state and consistent information leads to many synchronization issues in the design of a distributed system design. As we know, the resources of distributed applications are physically separated in their ecosystem. Due to the missing common resource factors, it is highly possible to have a delay in message delivery, and messages could even be lost. Consider the following diagram:

In spite of the previously listed complexities and challenges, distributed applications must be designed to leverage the complete advantages of the design to the end users. By leveraging the built-in concepts of the virtual centralized system, the distributed enterprise application is capable of demonstrating system characteristics such as reliability, transparency, efficiency, security, and easiness.

As a process to mitigate the listed challenges, the distributed applications are developed to deal with resolving several design issues.
