|h2. Amazon EC2 / EC2 Container Service |
|The [MathML Cloud Node.js backend API application|https://github.com/benetech/mmlc-api] runs inside a Docker container on the [BenetechLabsProjects ECS cluster|https://console.aws.amazon.com/ecs/home?region=us-east-1#/clusters/BenetechLabsProjectsCluster/services] |
|The main database for the MMLC application. |
|The Benetech Labs MongoDB cluster was originally launched [using this Amazon using an [Amazon provided quick start guide|https://aws.amazon.com/blogs/aws/mongodb-on-the-aws-cloud-new-quick-start-reference-deployment/]. However, there have now been some modifications made to the systems to facilitate backups so they cannot be recreated from scratch using the template without manually migrating the backup service.. |
|The cluster consists of three nodes spread across Amazon's us-east-1 region. As currently configured the cluster provided continued support for reads in the event the primary replica becomes unavailable. |
|h2. Amazon ElastiCache (Redis replacement) |
Not really sure what this does.

A [Jenkin's job|https://build.benetech.org/view/Deploy/job/Deploy-mmlc-app/] is used to deploy the application into Amazon S3. The job clones the mmlc-app git repository and uses the AWS CLI to upload files to Amazon S3.
h2. mmlc-api (backend)
A [Jenkin's job|https://build.benetech.org/view/Deploy/job/Deploy-ECS/] is used to deploy the application container onto the Benetech Labs ECS cluster. The job builds a Docker container which provides the runtime environment for the Node.js backend API.
