What is an advantage of hosting services on ArcGIS Server instead of relying solely on ArcGIS Online?

Hosting services on ArcGIS Server provides greater control over resource management and configuration compared to relying solely on ArcGIS Online. This advantage is significant because organizations can tailor their resources according to specific needs and preferences. ArcGIS Server allows administrators to manage hardware specifications, allocate resources effectively, and configure services based on operational requirements, leading to optimized performance for their particular use cases.

Additionally, ArcGIS Server can be integrated with other enterprise systems, enabling a more cohesive and customized environment that aligns with organizational workflows. This level of control is essential for businesses that demand flexibility, compliance with data governance policies, or need to handle sensitive information that may not be suitable for cloud hosting solutions like ArcGIS Online.

While the other choices might present benefits in certain contexts, they do not provide the same degree of management and customization that comes with running services directly on ArcGIS Server.
