What is a major limitation of traditional network-based monitoring approaches?

The major limitation of traditional network-based monitoring approaches is their inability to effectively monitor modern cloud application environments. Traditional methods primarily focus on monitoring traffic within on-premises networks and may rely on inspecting packets that traverse specific hardware or routers. This approach struggles with the dynamic and distributed nature of cloud environments where applications can scale horizontally, utilize microservices, and deploy across various geographical regions.

In contrast, modern applications often leverage cloud-native technologies, APIs, and containers, which traditional monitoring tools may not fully support. As a result, critical performance metrics, user experience insights, and application health indicators can be missed entirely when using outdated techniques that lack the necessary visibility into the cloud infrastructure.

While other choices mention benefits related to visibility, cost, and user insight, these attributes do not address the fundamental architectural limitations of traditional monitoring in the context of modern application landscapes. Hence, the correct answer highlights a significant challenge for organizations transitioning to modern technology stacks that require more advanced monitoring solutions.
