Problem

If the registration stops working, we won't know unless someone tells us.

Solution

Build a canary tester, possibly using AWS Lambda to run the steps of subscribing and what not and to alert us if there is a failure.

Problem

We are often asked by members to provide information about registrants. This is often handled by performing DB queries manually.

Solution

Provide the data using the web UI and a sweet library like bokeh or D3, etc.

Problem

When a Dockerfile is present in the root of the project, Elastic Beanstalk will build a Docker image and use that instead of pulling from the Docker hub repo. See the Image section in:

• https://docs.aws.amazon.com/elasticbeanstalk/latest/dg/single-container-docker-configuration.html#single-container-docker-configuration.dockerrun

Because of this, we can remove the image reference in Dockerrun.aws.json.

Why shouldn't Elastic Beanstalk just pull the repo?

• One good reason is that if someone accidentally pushes to the Docker Hub repo, then this can cause problems. Having EB use the Dockerfile as is makes some nice promises around what is tested and what is actually used. I'm specifically referring to a pipeline state of the project.

Solution

Remove the reference. Can also remove the Update key.

Problem

Want to generate stack using CF

Solution

keep it simple so rather than use ECS, set it up using Elastic Beanstalk + RDS.

• https://docs.aws.amazon.com/elasticbeanstalk/latest/dg/single-container-docker.html

Problem

We want to be able to move quickly and have solid apache settings set up.

Solution

Use best practices described in this YouTube video, Secrets of a WSGI master.

We hopefully won't have to update the WSGI settings too much. Find the documentation here:

• WSGIDaemonProcess

Problem

Users will send SMS to Twilio phone number which will be consumed by the service.

Solution

Integrate with Twilio to receive these messages.

Problem

Need alarms to understand if something went down.

Problem

Need to be able to send alerts.

Solution

Integrate with SNS to send alerts.

Problem

The service needs to be tested end-2-end in the gamma environment before being deployed to production.

Solution

Create service tests. This is probably a larger story around writing tests against both the web and twilio endpoints.

Problem

There are two forms that can be submitted to subscribers:

1. alert
2. follow up

Views need to be added to the project.

Solution

Add the views.

Problem

AWS instance monitoring doesn't have memory metrics being published to CloudWatch.

Solution

publish metrics using a script or some tool already created. Can set the tool up via UserData or something.

Problem

The server needs authentication.

Solution

Use auth0 for authentication so we can leverage the technology for both web and mobile.

Problem

It is unknown what the final notification will look like.

Solution

Add an example so the user knows what the final output will be. Alternatively, have the example update in real time based on the user's actions.

Problem

We need to create a pipeline to do deployments for us.

Solution

Create a pipeline that uses Code Pipeline which runs tests and deploys the new application to elastic beanstalk.

A lot of links and references can be found in this issue:

• #5

Problem

Need to create connection to RDS database.

Problem

Currently, the application in Elastic Beanstalk only has been verified using http, which is not secure.

Solution

Use the elastic load balancer or to perform SSL termination and enable https for the application.
