Amazon Service Limits
Amazon Web Services limits the number of machines or vCPUs that you can run at a given time. If you have Hybrik computing groups that exceed your AWS account limit, Hybrik will not be able to run additional instances in your account. In the Hybrik web console, you will see a pop up that states:
We had an issue requesting spot instances for the 'my_tag' computing group.
Your AWS account has exceeded its max spot instance limit(s).
Please check your AWS account limits and request a limit increase if needed.

Calculate your vCPU needs
You will have to request a specific number of vCPU for a given region. To calculate this, you can compare the maximum number of instances in your computing groups. Log into the Amazon Web Services console and choose EC2. From this menu, select Limits.
Next, choose the Calculate vCPU limit button.
In another window, pull up the Hybrik Web Console and navigate to Machines > Configuration to view your list of instances. If you need to enable different columns to view, choose the gear icon at the top of the window.
If you insert the Machine Type from Hybrik into the calculator and put in the Max Machines value, the calculator will tell you how many vCPU are required if you were to run all of the machines in your computing groups at once.
At the bottom of the calculator, it will show you your current limit and, if an increase is required, what the new limit would be. It will also tell you which request to make for the types of instances requested. AWS distinguishes between on-demand and spot vCPU, so be sure to click the link for the appropriate request type for your use case.
You can enter the information determined by the calculator.
Requests are per-region
Remember that this is calculated per-region, so if you need more vCPU in more than one region, you will need to make multiple requests.
