Great Post Misty,
I don’t have much knowledge of Content Delivery Networks, or Storage Area Networks, but very good information. From what i read, it appears most of the other networks previously described share communications and resources across a common area, local , metro, campus, etc, while a storage network is a dedicated high-speed network that connects to servers with storage space allowing for a centralized storage space. A CDN is a mass of distributed networks across the globe designed to deliver content quickly, regardless of location in effort to reduce latency. Thanks for allowing me to obtain new knowledge.
