To run:

# Edit deploy.sh: instance type and ami, then run the tests
AWS_S3_BUCKET="iguide.plntr" ./aws/deploy.sh

Or do it manually:

AWS_S3_BUCKET="iguide.plntr"
docker run -d --name ng -p 8080:80 -p 9000:9000 \
  -e "AWS_S3_BUCKET=$AWS_S3_BUCKET" \
  -e "AWS_ACCESS_KEY_ID=$AWS_ACCESS_KEY_ID" \
  -e "AWS_SECRET_ACCESS_KEY=$AWS_SECRET_ACCESS_KEY" \

Benchmark Results

Mean latency

We run 1000 GET requests in a row (by ab -c 1 -n 1000 .../small.txt) for a 13-byte small.txt file.

$ cat small.txt
Hello World!

Note: no special kernel tuning for better network performance was done.

Results	t1.micro Latency, ms	t2.small Latency, ms
Apache	1.160	1.160
Nginx	1.476	0.516
App	1.361	0.488
S3	133.188	130.023
Nginx+App	2.931	1.043
Nginx+S3	151.525	133.306
App+S3	247.013	241.796
Nginx+App+S3	264.335	244.868

t1.micro instance is 1 vCPU with 0.615GiB RAM, low network performance. t2.small instance is 2 2.5GHz vCPUs with with 2GiB RAM, low network performance.

XXX we have to run the same tests on instances with high expected network performance, e.g. m3.xlarge.
