Question 76

Multiple lower-configuration I/O-optimized ECS instances can be used withto deliver a high- availability architecture.
  • Question 77

    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.
    However, video data grows rapidly and the engineers find that the ECS will run out of storage space within 2 weeks.
    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.
