-AWS Performance Testbeds
-------------------------
-
-CSIT implements two virtual machine topology types running in AWS EC2:
-
-- **2-Node Topology**: Consists of one EC2 instance as a System Under
-  Test (SUT) and one EC2 instance acting as a Traffic Generator
-  (TG), with both instances connected into a ring topology. Used for
-  executing tests that require frame encapsulations supported by TG.
-
-- **3-Node Topology**: Consists of two EC2 instances acting as a Systems
-  Under Test (SUTs) and one EC2 instance acting as a Traffic Generator
-  (TG), with all instances connected into a ring topology. Used for
-  executing tests that require frame encapsulations not supported by TG
-  e.g. certain overlay tunnel encapsulations and IPsec.
-
-AWS EC2 Instances
------------------
-
-CSIT is using AWS EC2 C5n instances as System Under Test and TG virtual
-machines. C5n instances got selected to take advantage of high network
-throughput and packet rate performance. C5n instances offer up to 100
-Gbps network bandwidth and increased memory over comparable C5
-instances. For more information, see
-`Instance types <https://aws.amazon.com/ec2/instance-types/>`_.
-
-C5n features:
-
-- 3.0 GHz Intel Xeon Platinum (Skylake) processors with Intel AVX-512
-  instructions.
-- Sustained all core Turbo frequency of up to 3.4GHz, and single core
-  turbo frequency of up to 3.5 GHz.
-- Requires HVM AMIs (Amazon Machine Images) that include drivers for ENA
-  and NVMe. See :ref:`csit_ami` for more information.
-- Network bandwidth to up to 100 Gbps.
-- Powered by the AWS Nitro System, a combination of dedicated hardware
-  and lightweight hypervisor.

-
-CSIT is configured by default to use `c5n.4xlarge` in `eu-central-1` AWS
-region due to allocation stability issues with `c5n.9xlarge` in
-`eu-central-1` region.

-AWS EC2 Networking
-------------------
-
-CSIT EC2 instances are equipped with AWS Elastic Network Adapter
-(ENA) supporting AWS enhanced networking. Enhanced networking uses
-single root I/O virtualization (SR-IOV) to provide high-performance
-networking capabilities. For more information, see
-`Elastic Network Adapter <https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/enhanced-networking-ena.html>`_.
-
-For more information about the current advertised AWS ENA performance
-limits, see
-`Computed optimized instances <https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/compute-optimized-instances.html>`_.
-
-CSIT DUTs make use of AWS ENA DPDK driver supplied by AWS and specified
-in
-`amzn drivers dpdk <https://github.com/amzn/amzn-drivers/tree/master/userspace/dpdk>`_.
