EBS (Elastic Block Store) Imporatnt Points and Snapshots

EBS Storage:-

Here are some important points to consider for the EBS Storage. Consider previous post for more information on EBS.

1. Block level storage device.
2. Additional network attached storage.
3. Attached to only a single instance.
4. At least 1GB in size and at  most 1TB.
5. Each EC2 instance is backed by an EBS volume.
6. EBS RAID 0 for redundancy
Pre-Warm EBS Volumes
* EBS erases on first mount which causes loss of 5 to 50% OPS first time

Snapshots
1. Incremental Snapshots
2. Frequent snapshots increase durability
3. Degrade application performance while being taken.
