A large shopping mall deploys a new video surveillance system. The five-floor building in which the mall is located installed 35 HD cameras to monitor the major exits. The surveillance system is deployed on an ECS instance, which has four 2 TB data disks to store video data.

In this case, product is thought to be the best solution for addressing the storage challenge while ensuring quick access to historical video data when needed.
