See how AMI, EIP, snapshots, EBS volumes, and CloudWatch alarms work for EC2 instance to implement HA.
- [Instructor] In talking about high availability for EC2,…we have a number of objects.…I like to start the instance level,…which might seem weird because we have…more than one instance, that's the idea of HA.…But you'll see why as we get into this.…So starting with making the network address…transferable and reusable,…and that's by the use of an elastic IP address.…So I'll show you how to work with that.…The next thing is reusing the operating system…and any scripts that you might have…or code running on the particular instance,…and you do that through an Amazon Machine Image,…so launching from a custom baked AMI.…
This will reduce the boot time,…which is really important in terms of high availability,…and if you'll remember, the recovery time, the RTO,…it's a very important consideration…in how quickly you can get back up.…The data on your particular instance is saved…in elastic block storage.…It's a type of an object storage like S3, but it's for EC2.…So once you have these core best practices,…which I'll show you in the console in a couple minutes here,…
