Overall instance bandwidth quotas
As a general guide, the smaller sizes of C5
, M5
, and
R5
instance types can sustain up to 10- Gbps network performance. Larger
instance sizes can sustain between 10–25 Gbps. Smaller sizes of C5N
provide up
to 25 Gbps with the largest C5n
instances scaling up to 100 Gbps. Some examples
of instance type, configuration, and network performance:

Aggregate bandwidth throughput for instances between Availability Zones (within a VPC) or
between instances in a peered VPC scenario is 25–100 Gbps, depending on instance type (see Table
1). Similarly, aggregate bandwidth to VPC endpoints, such as Amazon S3, is 25- 100 Gbps. Single TCP
flow is limited to 10 Gbps for instances in the same placement group and 5 Gbps between
instances anywhere else. (TCP flow is
defined as traffic going through a single TCP port.) A placement
group is a logical grouping,
or cluster, of instances within a single Availability Zone, that
allows applications to use low latency 10-Gbps network. For more information, see
