Benchmarks

Tests performance of various proxies/load balancers. Based on the blog post https://www.loggly.com/blog/benchmarking-5-popular-load-balancers-nginx-haproxy-envoy-traefik-and-alb/.

We test the following proxies:

Caddy
Envoy
HAProxy
NGINX
Traefik

IMPORTANT! Be sure to SSH into the client VM and run the test against the proxy_server VM from there. Running the test from within the AWS VPC will reduce Internet latency.

Defaults to the AWS "US-East-2 (Ohio)" region.

NOTE: The AWS plugin for Terraform can be finicky. The deployment may or may not work the first time. In that case, use terraform taint aws_instance.proxy_server for example to try it again.

Setup

Perform these steps:

In the AWS Console, create a new SSH keypair (default name is "benchmarks"):
- Go to EC2 > Key Pairs > Create Key Pair.
- Name it "benchmarks".
- Save the .pem file to this project's directory.
- Update the file's permissions with chmod 400 ./benchmarks.pem
Run:

terraform init
terraform apply -auto-approve -var 'aws_access_key=<YOUR_ACCESS_KEY>' -var 'aws_secret_key=<YOUR_SECRET_KEY>'

Log into the client server with ssh -i ./benchmarks.pem ubuntu@<IP_ADDRESS> and run the tests:

/tmp/run_tests.sh | tee results.txt

Performance tests use https://github.com/rakyll/hey.

To tear down the servers:

terraform destroy -force -var 'aws_access_key=<YOUR_ACCESS_KEY>' -var 'aws_secret_key=<YOUR_SECRET_KEY>'
