In AWS I have a Elastic Beanstalk application that is using m3.medium instance, I went to configuration to see what disk my Root device is using, it says Container default and if I click on Learn More it says
Each instance in your environment is configured with a root volume. The root volume is the Amazon EBS block device attached to the instance to store the operating system, libraries, scripts, and your application source code. By default, all platforms use general purpose SSD block devices for storage.
So it seems to be using SSD which is what I want, but if I go to EC2 and look at the volume attached to this ec2 server it says it is of type standard . And when I look at volume types help standard seems to refer to a defunct magnetic drive
So I'm unsure if I am using SSD or non SSD - I want to use SSD. I am also unclear that if I use the default volume do I pay for that like any other volumes or is it included in the price of the instance ?
Update
I now changed configuration from m3.medium to t2.medium. After it had finished redeploying in EC2 volumes I noticed there was a new 8GB volume replacing the previous one (there were two volumes listed whilst redeploying was occurring), again this says standard, clicking on Elastic Beanstalk configuration notes it has Root volume type set to (Container default). So again I am unclear is this SSD or magnetic ?
