Cloud service

Software architecture

This page provides a short overview of the cloud service, from a software architecture perspective.

System Context

Structurizr is a collection of web-based tooling for the creation and publication of software architecture models. It makes use of a number of other cloud-based services including:

• Amazon Web Services SES - used for sending e-mails.
• Braintree Payments - a validated Level 1 PCI DSS compliant service provider, used for payment processing.
• Papertrail - used for application logging.
• Pingdom - used for application uptime monitoring.
• MaxMind GeoIP - used for determining the user's country for tax purposes.

Containers

In summary, Structurizr consists of two server-side Java/Spring MVC applications (one hosting api.structurizr.com, and one hosting structurizr.com), with data being stored in a combination of a MySQL database and Amazon S3. Most content is viewed/modified by users via a collection of single-page applications written in JavaScript running in the user's web browser.

Deployment

Structurizr is deployed using a number of cloud-based services including:

• Amazon Web Services ECS - used for application hosting.
• Amazon Web Services RDS - used for data storage (users, workspace metadata, etc).
• Amazon Web Services S3 - used to store your workspace, and the PNG versions of diagrams.
• Redis - used for HTTP session storage.
• CloudFlare - used for DNS, routing and SSL services (not shown).
