<div class="moz-cite-prefix">AWS does put limits on resources any
one AWS account can use (see<span class="Apple-converted-space"> </span><a
href="http://docs.aws.amazon.com/general/latest/gr/aws_service_limits.html"
target="_blank" style="color: rgb(17, 85, 204);">here<span
class="Apple-converted-space"> </span></a> for details).
Specifically see <a
href="http://aws.amazon.com/ec2/faqs/#How_many_instances_can_I_run_in_Amazon_EC2">here</a>
for limits regarding EC2s. You can make requests to AWS to
increase limit bounds. Also note there are certain actions AWS
users are not allowed take (see<span class="Apple-converted-space"> </span><a
href="http://aws.amazon.com/aup/" target="_blank" style="color:
rgb(17, 85, 204);">here</a><span class="Apple-converted-space">
)</span>, if you violate any of those policies Amazon has right
to deny service to you. <br>
<br>
And another thing to consider is the time of the year. AWS started
because Amazon wanted to make more use of its resources when they
were less than active. I'm not sure what proportion of AWS
resources are still used by Amazon itself, but I would think with
holidays approaching the EC2s might be less than available as
compared to the start of 2015.<br>

Good Luck.<br>

<div>1. if there a way to query AWS in advance to see if they
have the 300 EC2 availables? I dont want to find out after 299
nodes that they out of that EC2 type. I am not sure if
StarCluster already check for that.</div>

<div>2. Would it be better to create the cluster with less nodes
and then add them 20 at a time?</div>
