Fault tolerance at EBS

As we know, EBS can be attached to an instance as a physical volume. Here, we can define the redundant array of independent disk (RAID) as well, although it will be software-based RAID. RAID basically gives fault tolerance, which means that if anything goes wrong with the volume you will not lose your data.

Here is the trick—while defining RAID, we must see the IOPS and throughput requirements of the application. This is because defining RAID affects your IOPS and throughput. 

In AWS, we can define RAID 0 and RAID 1, while RAID 5 and RAID 6 are not recommended.
