What Are the Differences Between Cloud SSDs and Local SSDs?
Cloud SSDs support scale-out. Therefore, you are advised to use them. The differences between cloud SSDs and local SSDs are as follows:
- Cloud SSDs
- Cloud SSDs use EVS as storage media and can be scaled out as data grows. This is more flexible.
- Cloud SSDs are not bound to the ECS flavor. Therefore, you can adjust the flavors of cloud SSDs when needed.
- Local SSDs
- Local SSDs use ECS local disks as storage media. They have fixed capacity and higher performance but cannot be scaled out.
- If the capacity is insufficient, you have to add more nodes to increase capacity. The flavors of local SSDs cannot be adjusted.
