how many ec2 instances will be launced after running bosh deploy? (cloudfoundry)

xiaoshan fang

I am deploying cloudfoundry on aws.

While I running bosh deploy, the vms created exeeds the limit of default number of EC2 instances. Below is the error message:

*Your quota allows for 0 more running instance(s)*

How many instances do I need in total? Is there any method to reduce the number of vms?

Could you help?
