Scaling Globally: Priority Pass's Journey with AWS Amplify
Overview
Priority Pass is a market-leading provider of airport lounge access for frequent travelers
Their web platform and mobile app are the primary way customers interact with the service
However, their legacy web platform was struggling to scale and perform globally to meet the needs of their growing customer base
Challenges with Legacy Platform
High traffic volumes and global user base led to performance and scalability issues
Reliance on a legacy CMS (Sitecore) with custom integrations to backend APIs
Expensive and brittle hosting infrastructure (EC2 and databases)
Slow deployment process and difficulty handling traffic spikes
Modernizing with AWS Amplify
Evaluated options like Amplify and Vercel, chose Amplify for cost-efficiency and alignment with AWS ecosystem
Started with a proof-of-concept, then migrated lower-traffic sites before tackling priority-pass.com
Partnered closely with AWS to address technical challenges around caching, DNS, and integrations
Adopted a monorepo architecture with Nx tooling and automated CI/CD using GitHub Actions
Key Benefits
Cost Savings: Hosting costs reduced from $180,000/year to $20,000/year
Improved Performance: No traffic-related outages since migration, zero manual scaling required
Faster Deployment: Hundreds of deployments per month vs. 1-2 per week previously
Better Developer Experience: Simplified hosting, ephemeral environments, and framework-agnostic approach
Technical Details
Migrated to a Next.js-based architecture, using Contentful as a headless CMS
Leveraged Amplify's managed services for hosting, CI/CD, and optional backend capabilities
Utilized Amplify's Typescript support to integrate with other AWS services as needed
Observed some limitations around observability and missing features like Incremental Static Regeneration (ISR)
Business Impact
Enabled Priority Pass to scale their web platform to support millions of global customers
Improved stability and performance, reducing operational overhead and providing a better user experience
Freed up engineering resources to focus on new feature development and innovation
Positioned the company for continued growth and expansion of their market-leading travel services
Example Use Case
Priority Pass customers can use the mobile app or website to generate digital membership cards, pre-book lounge access, and access other travel services
The Amplify-powered platform handles high traffic volumes and global usage patterns without disruption
This allows Priority Pass to deliver a seamless, reliable experience for their frequent traveler base, differentiating their service in a competitive market
Conclusion
By migrating their web platform to AWS Amplify, Priority Pass was able to significantly improve the scalability, performance, and cost-efficiency of their customer-facing applications.
