This is a simple cloud application that I developed alongside the Udacity Cloud Engineering Nanodegree. It allows users to register and log into a web client, post photos to the feed, and process photos using an image filtering microservice. Following are the services involved in this project:

• “user” - allows users to register and log into a web client,
• “feed” - allows users to post photos, and process photos using image filtering
• “frontend” - acts as an interface between the user and the backend-services
• "reverseproxy" - For resolving multiple services running on same port in separate containers

Correspondingly, the project is split into following parts:

1. The RestAPI Feed Backend, a Node-Express feed microservice.
2. The RestAPI User Backend, a Node-Express user microservice.
3. The Simple Frontend - A basic Ionic client web application which consumes the RestAPI Backend.
4. Nginx as a reverse-proxy server, when different backend services are running on the same port, then a reverse proxy server directs client requests to the appropriate backend server and retrieves resources on behalf of the client.

The application is divided the into smaller services for user, feed, frontend, reversproxy using Docker.

I have created Kubernetes resources and deployed the application to Kubernetes cluster using kops + kubectl. I have also extended the application with deployments to be able to apply rolling-updates and rollbacks.

I have also integrated Travis CI for automating continuous integration (CI) and continuous delivery (CD).
