-AWS Instances
--------------
-
-CSIT is using C5n instances for high compute applications that can take
-advantage of improved network throughput and packet rate performance. C5n
-instances offers up to 100 Gbps network bandwidth and increased memory over
-comparable C5 instances [aws_it]_.
-
-Features:
-
-- 3.0 GHz Intel Xeon Platinum processors with Intel Advanced Vector Extension
-  512 (AVX-512) instruction set.
-- Sustained all core Turbo frequency of up to 3.4GHz, and single core turbo
-  frequency of up to 3.5 GHz.
-- Requires HVM AMIs that include drivers for ENA and NVMe [aws_ena]_.
-- Network bandwidth increases to up to 100 Gbps, delivering increased
-  performance for network intensive applications.
-- 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 Elastic Network Adapter (ENA)
----------------------------------
-
-Enhanced networking uses single root I/O virtualization (SR-IOV) to provide
-high-performance networking capabilities on supported instance types. SR-IOV is
-a method of device virtualization that provides higher I/O performance and lower
-CPU utilization when compared to traditional virtualized network interfaces
-[aws_ena]_.
-
-Current advertised limits are captured in [aws_limits]_.
