13. Solution Details – Heroku
Why we chose Heroku
▪ Customer facing application functionality
• Java gives us more flexibility for pure custom solution.
• Customer facing sites do not need full Salesforce capabilities and would be cost
prohibitive for user licensing.
▪ Integration
• Real-time processing on Heroku vs. scheduled jobs in Force.com.
▪ Service options
• Availability of more ready-to-go functionality via add-ons
▪ Scalability
• Start small and add dynos as the application grows

14. Team store and fundraising site
▪ School specific branding, style, and content
▪ Hundreds of school sites rendered via single set of CSS and HTML templates

15. Custom fundraising e-commerce solution
▪
Full cart and checkout e-Commerce functionality
▪
Adobe Scene 7 renders dynamic product images
▪
Social links allow shoppers to share items
▪
Custom Heroku authentication for customers

16. Heroku Application Structure
▪ Java / Spring MVC core
▪ Add-on services
▪
Cloudant storage
▪
Memcachier caching
▪
SendGrid email service
▪
CloudAMQP Message Queueing
▪ Adobe Scene 7 dynamic image creation
▪ S3 static asset hosting
▪ New Relic monitoring

17. Heroku architecture constraints
▪ Web dynos must respond in 30 seconds or less
▪ Dynos must start up in 60 seconds or less
▪ Heap size
▪ 1x dynos get 512 MB, 2x dynos get 1024MB
▪ No session state
▪ Need persistence solution such as Cloudant
▪ No web server or filesystem
▪ S3 or similar solution for static assets (CSS, javascript, images, etc.)

18. Heroku – Best practices and lessons learned
▪ Caching strategy
▪
Frequently accessed pages pre-generated and cached for fast web dyno response
▪
Two level cache for header, footer, catalog and product HTML components
▪
Memcache provides fast primary lookup
▪
If item not present in memcache, retrieve from Cloudant if not dirty
▪
If dirty, request regeneration of HTML component
▪
Product and account information also cached in this manner
▪ Long running processes
▪
Use worker dynos, message queues and AJAX calls to check status on web pages
▪
Page generation, order completion

19. Heroku – Best practices and lessons learned
▪ Also use worker dynos for batch processing
▪
Integration worker to update Salesforce from AS/400 ERP
▪
Batch job to re-generate dirty HTML page components in the background
▪ Cloudant for session persistence
▪ Take advantage of add-on services to reduce implementation time
▪
No need to rebuild functionality
▪
Use developer level services for prototyping and development
▪ Throughput and scaling
▪
Java web dynos support multithreading – use this to boost your throughput
