  • ECS instances support CPU and memory scaling, and bandwidth upgrades while the instances are running. You can also downgrade instances based on your needs. This does not include ECS instances with local storage.
  • A maximum of 16 data disks can be attached to each ECS instance. You cannot reduce the disk size after you have expanded the data disks.
  • The ECS bandwidth is measured in megabits per second (Mbps). The bandwidth speed ranges between 0 and 200 Mbps. You can also temporarily upgrade the bandwidth, or downgrade the configuration of your ECS instances when you renew the subscription.
