  3. 3. Introduction Last year at Dreamforce to interview speakers talking about Heroku and meet other early adopters of the Platform.  Released the first version of Heroku Salesforce Playbook on Xmas 2012 • Heroku history • Introduction to Heroku Toolbelt • Java and Ruby tutorial to get started  Next release available soon (Xmas 2013) • Presenting 15 detailed use cases • Introduction to the different Salesforce APIs
  4. 4. Introduction Today the objective is to present some common mistakes done when building Cloud app (including on Heroku) and learn how to avoid them  Platform / language neutral  First we need to understand how Cloud Apps are different ? • Heroku 12 factors • Cloud App with remote Data/API
  5. 5. Cloud App Architecture
  6. 6. The API latency syndrome How to detect it ?  Pages taking ages to display  API Quota reached quickly  More than 5 API calls per action SOLUTION : CACHE EVERYWHERE IT’S REQUIRED !!
  7. 7. Cache OR Call pattern Reduce overall API Latency:
  8. 8. Understanding Caching options Cache vs Data replication vs Data synchronization:  Caching weakness is that you need to sweep it regularly and automate it  Data replication weakness is that bi-directional update replication implies potential conflict which need a proper management  Data synchronization using third party tools such as CloudConnect is a really convenient way to avoid
  9. 9. API cache warming Principle  You already know that your application need to get the list of remote static objects  Add a worker dedicated to Cache warming  Store all remote Static records locally  Define refreshing strategy on the worker itself
  10. 10. API cache warming
  11. 11. Environment management Is your local machine the Test env ?  Heroku app might behave differently than on your Local Machine or Test Server • Assets compilation failing • Process running differently • Static Configuration • Memory management
  12. 12. Environment management Solutions:  Dev ENV as clause of Heroku PROD ENV than possible  Duplicate your Production ENV for TEST  Use Foreman locally  Share Heroku config with your team and load it as part of your ENV  Of course you can spin up and down TEST env
  13. 13. Salesforce custom APEX End Point Objective:  Reduce API calls  Access Hidden Business Logic Creating custom APEX endpoint:  Group API calls  Aggregate multiple records in ONE call  Trigger complex Apex code from a REST endpoint
  14. 14. No clues on errors Logplex principle  Logs are an event Stream (12 Factor number XI) Monitor early, drive safely:  Start recording logs from the beginning with enough storage capacity  Monitor your app  Make sure your logs are relevant
  15. 15. Log stream , Papertrail, New Relic
  16. 16. App capacity estimation Load test your app
  17. 17. Conclusion  Be creative  PoC are not expensive  Use the right technology/language for the right challenge  Check the playbook, share your ideas with Book authors

Vincent Spehner Heroku Practice Manager, @vzmind “If there's anything more important than my ego around, I want it caught and shot now.” Douglas Adams “So long, and thanks for all the fish.” "So once you do know what the question actually is, you'll know what the answer means.” “How many roads must a man walk down?” “Looking up into the night sky is looking into infinity — distance is incomprehensible and therefore meaningless”
