Citrix SD-WAN Platforms
Minimum requirements
• AWS EC2 Instance Type: c4.2xlarge, c4.4xlarge, c5.xlarge, c5.2xlarge, c5.4xlarge, m4.2xlarge,
m4.4xlarge, M5.2xlarge, m5.4xlarge
• Virtual CPU: 8
• RAM: 15 GB

• Network Interfaces: minimum of 2 (one management, one for LAN/WAN)
• BYOL – bring-your-own-license and subscription
From 11.3 release onwards, Citrix SD-WAN has introduced support for the M5 and C5 instances. The
newer AWS regions such as Hong Kong and Paris only support M5 and C5 instances.
The M5 and C5 instances have improved hardware performance and are designed for higher demand-
ing workloads. The M5 and C5 instances deliver better price/performance than the M4 instances on a
per-core basis.
NOTE
The M5 and C5 instances are supported from a fresh provision of 11.3 and higher version only. To
keep using the M5 and C5 instances, you cannot downgrade from 11.3 version since the M5 and
C5 instances are not supported on any firmware version prior to 11.3 release.
Limitations
• AWS does not allow bridging of interface so Fail-to-Wire is not an option for configuring interface
groups.
• Instances provisioned with 10.2.4/11.2.1 versions, AMIs cannot change their instance type to
M5/C5.
