EC2 instance store
- [Instructor] In an earlier movie, you understood how you could optimize EBS volumes depending on your workload requirements. But the performance of EBS volumes is limited by its design. EBS volumes are hosted on shared storage devices and are made available to EC2 instances as network attached block storage. Hence the bandwidth of the discs is limited by the performance of the network, over which they are connected. As a result, EBS volumes are not the fastest in performance because the service has to move data over a network. Because of these limitations, there could be situations where EBS volumes performance may not be enough. For example, if the IOPS on your EBS volume increases to the maximum value, further I/O operations will queue up. At this point, the EBS volume's performance is limiting the performance of your application. You can address this by using storage disks that are directly attached to EC2 instances.…
