What Azure service should be used to manage and organize network resources seamlessly?

The Azure service best suited for managing and organizing network resources seamlessly is Azure Resource Manager. This service provides a comprehensive framework for deploying, managing, and organizing resources in Azure. Through Azure Resource Manager, you can define your infrastructure as code, enabling you to use templates for consistent deployments and organization of resources. It also supports role-based access control (RBAC), which allows you to manage access to specific resources based on user roles, thus enhancing security and governance.

Furthermore, Azure Resource Manager allows you to group related resources, making it easier to manage them collectively rather than individually. This organization simplifies tasks such as monitoring and scaling, as you can effectively manage the entire environment as a cohesive unit. It streamlines operations and fosters a more efficient approach to resource management in Azure, ensuring that users can utilize and organize their network resources effectively.

Other options, like Azure Traffic Manager and Azure Load Balancer, serve specific roles within the network management domain, but they do not provide the overarching management capabilities and organizational features that Azure Resource Manager offers. Azure App Service is primarily focused on hosting web applications, adding another layer of functionality that does not relate to network resource management specifically.
