What is a common disadvantage of point-to-point integration?

Point-to-point integration involves directly connecting individual systems to each other, which can lead to a significant increase in complexity and maintenance overhead as the number of integrations grows. Each new integration requires additional connections, leading to a web of interdependencies that can be difficult to manage. As more systems are added, the system can become more challenging to troubleshoot and maintain, since a change in one system could necessitate changes in multiple other systems due to the direct connections established.

This method also increases the risk of errors, because any update or issue in one system can have a domino effect on others. The maintenance of these direct connections can lead to substantial overhead related to documentation, version control, and coordination among teams managing different parts of the integration. Therefore, the correct choice highlights the inherent drawbacks of point-to-point integration in a growing environment where scalability and ease of management become critical considerations.
