# AWS CloudFront latency

Comparing latency when using AWS CloudFront at long distances as opposed to calling a web service directly.

> Cache is disabled to to force round trips to the server

## Setup

This project runs my [stressbox][1] image for testing as default. 

Create a private ECR:

```sh

aws ecr create-repository --repository-name stressbox

```

Pull the image and tag it with the repository name in the account:

```sh

account=""

region=""

docker pull ghcr.io/epomatti/stressbox

docker tag ghcr.io/epomatti/stressbox "$account.dkr.ecr.$region.amazonaws.com/stressbox"

```

Push the image to the account repository:

```sh

aws ecr get-login-password --region $region | docker login --username AWS --password-stdin $account.dkr.ecr.$region.amazonaws.com

docker push $account.dkr.ecr.$region.amazonaws.com/stressbox

```

Create a `.auto.tfvars` file with the ECR image URL:

```terraform

ecr_image = ".dkr.ecr..amazonaws.com/stressbox:latest"

```

Create the infrastructure:

```sh

terraform init

terraform apply -auto-approve

```

Run latency and access tests.

---

### Clean-up

Delete the resources:

```sh

terraform destroy -auto-approve

aws ecr delete-repository --repository-name stressbox --force

```
