If you guys use AWS, have you taken a look at EBS provisioned IOPS? EBS provisioned IOPS comes to mind here since it allows you to specify the desired IOPS of a volume, and provides an SLA.

> Providers don't provide a minimum IOPS, so they can just drop you.

The reason I ask is because the blog post generalizes a lot about what cloud providers offer or what the cloud is capable of, but doesn't explore some of the options available to address those concerns, like provisioned IOPS with EBS, dedicated instances with EC2, provisioned throughput with DynamoDB, and so on.

EBS goes up to 16TB, we need an order of magnitude more.

You're right that the blog post was generalizing.

BTW We looked into AWS but didn't want to use an AWS only solution because of maximum size, costs, and the reusability of the solution.

Per disk. You can attach multiple disks to a single EC2 node.

So, RAID multiple EBS volumes and you have a larger disk.
