Skytap service limits

Your Skytap account has limits for VMs and environments for each region, as well as network and other limits for the overall account. This page provides details about those limits, both account-wide and for all Skytap regions.

For additional networking details, see What IP addresses and port ranges does Skytap use?.

If you’re a primary administrator and you need specific capabilities that exceed these limits, contact support@skytap.com. Include your name, email address, and the name of your organization. If you’re a standard user or administrator, work with your primary administrator to request an increase.

VM limits

Each VM has the following virtual hardware and metadata limits:

Item	Limit

IOPS for x86 VMs

IOPS for x86 VMs scale with the amount of RAM allocated to the VM, depending on region.

US-West

RAM-based IOPS scaling for x86 VMs in US-West.
