Tutorial: Operations

This project is intended to be statically hosted with a CDN and cached so that resources can be served efficiently at any scale, and using CI/CD such that pushing code to the master branch is sufficient to update the project for all consumers (given sufficient cache-invalidation time).

Overview

• An AWS Cloudfront Distribution provides the CDN caching layer that delivers content to the user quickly, without consuming the more expensive S3 resource directly.
• An AWS S3 Bucket stores the static files generated by CI/CD efficiently at any scale.
• Bitbucket's CI/CD pipeline automatically recognizes changes to the source code and runs automated tests before updating the static files and invalidating caches.

CI/CD

Changes to the master branch trigger updates to the CDN. Our pipeline automatically builds the library, updates the files stored in AWS S3, and files a cache invalidation with cloudfront such that edge locations begin to serve updated content within minutes.

See bitbucket-pipelines.yml for the steps run.
