You encountered a soft limit of 20 instances per region. Submit the limit increase form and retry the failed requests once approved.
AWS allows you to provision no more than 20 instances per Availability Zone. Select a different Availability Zone and retry the failed request.
You need to use Amazon Virtual Private Cloud (VPC) in order to provision more than 20 instances in a single Availability Zone. Simply terminate the resources already provisioned and re-launch them all in a VPC.
You encountered an API throttling situation and should try the failed requests using an exponential decay retry algorithm.

You must know how many customers the company has today, because this is critical in understanding what their customer base will be in two years.
You must find out the total number of requests per second at peak usage.
You must know the size of the individual objects being written to S3, in order to properly design the key namespace.
In order to build the key namespace correctly, you must understand the total amount of storage needs for each S3 bucket.
