Amazon VPC Limits

The following table lists the limits related to Amazon VPC. Unless indicated otherwise, you can request an increase for any of these limits by using the Amazon VPC Limits form.

ResourceLimitComments

VPCs per region

5

This limit can be increased upon request. The limit for Internet gateways per region is directly correlated to this one. Increasing this limit will increase the limit on Internet gateways per region by the same amount.

Subnets per VPC

200

This limit can be increased upon request.

Internet gateways per region

5

This limit is directly correlated with the limit on VPCs per region. You cannot increase this limit individually; the only way to increase this limit is to increase the limit on VPCs per region. Only one Internet gateway can be attached to a VPC at a time.

Virtual private gateways per region

5

Only one virtual private gateway can be attached to a VPC at a time. This limit can be increased upon request.

Customer gateways per region

50

This limit can be increased upon request.

VPN connections per region

50

This limit can be increased upon request.

VPN connections per VPC (per virtual private gateway)

10

Route tables per VPC

200

Including the main route table. You can associate one route table to one or more subnets in a VPC.

Entries per route table

50

This is the limit for the number of non-propagated entries per route table. This limit can be increased upon request; however, network performance may be impacted.

Elastic IP addresses per region for each AWS account

5

This is the limit for the number of VPC Elastic IPs you can allocate within a region. This is a separate limit from the EC2 Elastic IP address limit. This limit can be increased upon request.

Security groups per VPC

100

This limit can be increased upon request; however, network performance may be impacted, depending on the way the security groups are configured.

Rules per security group

50

This limit can be increased or decreased upon request, however, the multiple of the limit for rules per security group and the limit for security groups per network interface cannot exceed 250. For example, if you want 100 rules per security group, we decrease your number of security groups per network interface to 2.

Security groups per network interface

5

This limit can be increased or decreased upon request; however, the multiple of of the limit for security groups per network interface and the limit for rules per security group cannot exceed 250. For example, if you want 10 security groups per network interface, we decrease your number of rules per security group to 25.

Network ACLs per VPC

200

You can associate one network ACL to one or more subnets in a VPC. This limit is not the same as the number of rules per network ACL.

Rules per network ACL

20

This is the one-way limit for a single network ACL, where the limit for ingress rules is 20, and the limit for egress rules is 20.

BGP Advertised Routes per VPN Connection

100

This limit cannot be increased. If you require more than 100 prefixes, advertise a default route.

Active VPC peering connections per VPC

This limit can be increased via special request to AWS Support. The maximum limit is 125 peering connections per VPC. The number of entries per route table should be increased accordingly; however, network performance may be impacted.

Outstanding VPC peering connection requests
