About the Client
DispatchHealth delivers high-quality, on-demand urgent care directly to patients’ homes, giving patients an alternative to emergency rooms, urgent care clinics, and hospital visits. Their model reduces healthcare costs, increases convenience, and improves patient outcomes by bringing medical teams directly to where patients live.
THE CLIENT'S INITIAL REQUEST
DispatchHealth partnered with DBB Software to design a front-end infrastructure approach that could be consistently reused across applications while meeting high security and operational standards.
Create a Shared Infrastructure Pattern
Define a standardized front-end delivery architecture that all applications could follow, reducing fragmentation and operational overhead.
01
Improve Security at the Edge
Ensure front-end applications follow a security-first model, including strict content security policies and controlled request handling.
02
Enable Scalable Global Delivery
Support fast, reliable content delivery across regions without adding infrastructure complexity.
03
Keep Operations Simple and Maintainable
Introduce an approach that is easy to maintain, deploy, and scale without increasing hosting costs or deployment friction.

SOLUTIONS WE DELIVERED
DBB Software designed and implemented a standardized, serverless front-end delivery approach to support DispatchHealth’s growing suite of applications.
Serverless Front-End Architecture
Designed and implemented a serverless front-end delivery model based on Amazon CloudFront, S3, and AWS Lambda, establishing a consistent and reusable deployment standard across applications.
Edge-Level Security Controls
Centralized security enforcement at the edge using Lambda functions to manage Content Security Policies and request handling, ensuring consistent protection across all front-end applications.
Global Performance Through CDN Caching
Enabled fast and reliable content delivery by leveraging CloudFront’s global caching capabilities, serving assets from regional edge locations to improve availability and performance.
Standardized Front-End Delivery Across Applications
Rolled out the serverless delivery pattern across seven production applications, allowing teams to adopt a unified infrastructure approach without additional operational overhead.
RESULTS ACHIEVED
Standardized Front-End Delivery
Established a single, reusable infrastructure pattern adopted across multiple applications.
Security-First Architecture
Centralized CSP enforcement and request handling through Lambda improved consistency and reduced security risks.
Improved Maintainability
Serverless delivery simplified operations and reduced long-term maintenance effort for front-end teams.
Scalable Global Performance
CloudFront caching enabled fast content delivery across regions without added infrastructure complexity.
Zero Cost or Deployment Regressions
The new setup met all requirements without increasing hosting costs or deployment times.
