Patterns Library Architecture

AWS CloudFront hosts and exposes both: patterns.boston.gov and assets.boston.gov

patterns.boston.gov

Overview

This sub-domain is a centralized, public CDN serving theme/style and branding elements for City of Boston.

Architecture

• The main fleet pattern library is located in an s3 bucket named patterns.boston.gov

• The root folder of this s3 bucket is referenced by a CloudFront Distribution (arn:aws:cloudfront::251803681989:distribution/E1PA4V9JL1L6RU) which is exposed as a public website at the URL https://d2hk73kicft6oi.cloudfront.net.

• The CoB LAN team have created a sub-domain patterns.boston.gov on the public DNS servers, and this sub-domain has a CNAME which points tohttps://d2hk73kicft6oi.cloudfront.net.

• The AWS Certificate Manager (us-east-1) creates manages a AWS wildcard certificate for patterns.boston.gov (why not use cob main wildcard??). This certificate is applied to the CloudFront Distribution to secure HTTPS traffic to the sub-domain endpoint/s.
