I have purchased an EC2 Reserved Instance. Its a t3large in some region, lets say r1. I want to install MySQL on this instance.

Now when I create the EC2 instance (t3large in r1), I come to the Storage tab:

enter image description here

8GB is too small for this server, I want the instance to have 100GB storage.

Questions:

  1. If I change the storage from default 8GB to 100GB, would the instance attribute still match my reserved instance? Or because the storage is different I will be charged the On Demand rate?

  2. Lets assume I change the default 8GB to 100GB, is this storage persistence? I have heard that instance store is not persistence... but I am not really sure if this 100GB is within the instance store? Also if this storage is not persistence, how should I add persistence storage to my EC2?

  1. I'm pretty sure reserved instances don't cover the cost of EBS, but I can't find any document that states that at the moment. So you can choose however much storage you need. You'll pay for that separately.
  2. t3.large doesn't have instance storage (list of instances that do). You're adding EBS storage which is network attached. It will be deleted when the instance is deleted (unless it's a secondary drive where you chose not to delete it with the instance).
