We consider RAID 1 when fault tolerance is more of a priority than performance. In RAID 1, data is mirrored into volumes. It's required for critical applications. Just assume that we have a critical application where we are not in a position to lose any data. For this, we must use RAID 1. In RAID 1, if we have added two volumes with 100 GB GP2 that have 160 MBps of throughput, unlike RAID 0 it will give you only 100 GB storage with 160 MBps of throughput.
Now, let's see how to define RAID on AWS. First, log in to the AWS Console and search for an EC2 instance where you want to define RAID. Here, we will go with RAID 0. To do this, we will add two identical volumes to the EC2 instance:
Once the volume is created, we need to attach ...
