Okay, so for our very last demo of the day, let's go ahead and upgrade our instance configuration. So I'll go click on Manage for our master here, and I'll go ahead and upgrade him to a different instance specification. To do that, I just click on Change Specifications, and from there, I'll be able to choose a larger instance class, so let's go ahead and do that. Let's upgrade to a c1.large, which has eight CPU cores and 16 gigabytes of RAM, so this is much, much bigger than our previous instance, and we can also, if we want, scale the storage, so maybe scale that up to 10 gigabytes, and I can choose to switch immediately after data is migrated onto the new instance. And keep in mind, that this is actually going to happen entirely in the background without any downtime, because I have an HA instance, so when the master is offline during the upgrade, the slave can take over, so this whole thing should happen without any downtime. And I can click Pay Now, and that will begin the upgrade process.

So I have now paid for our instance, and the upgrade process should get started. I'll go ahead and close this window and we'll refresh, and just wait for the upgrade to complete. So after waiting a bit, we can see that the upgrade has finished, we're now in the Running state here, still pay-as-you-go, but we now have eight CPU cores and 16 gigabytes of RAM, so it all worked and our storage has changed from 5 gigabytes to 10 gigabytes, and that was easy, it was all done entirely online without any intervention from us, except to initiate the upgrade in the first place. That's it for this demo, thank you for joining.
