- 4. Dy1 a P yF m o la ra e rk w h ://p y m o .o / ttp la fra e rk rg w Very interesting Java/Scala web framework We built a basic CRUD app and deployed it to Heroku in a couple of hours Quick development, easy; similar to Rails / Grails but with Java or Scala db Evolutions. Automatic upgrade/revert of schemas – very cool
- 5. Hro u ek h ://hro u m ttp e k .co Cloud “Platform As A Service” Deploy just about everything (No .Net, sorry) Easily scale once your app is ready Deploy with git! Not for every app: limitations on size of processes, architecture
- 6. P dctiv To rou ity ols Small handheld whiteboards for notes Camscanner Plus – high-contrast pictures of whiteboards Lightscribe pen – records what is written with it and audio – Runs Java Jrebel – Deploys code changes instantly into running app Hipchat – team / company IRC Bottles of Jameson Whiskey
- 7. Cn uu Dp y e t otinos e lomn I wish we were close to doing this Vagrant – easy virtualization scripting for developers Keep code deployable Instrument app with JMX Cloud Deployment Caching with Varnish, Terracotta Deploy to small % of users as “canary test” Test rollbacks, killing servers constantly Service discovery in cloud deployments is hard
- 8. NoJ e4 Graph database Holds nodes & relationships instead of rows/columns Patients, staff with interaction times Pull which staff saw Patient X easily and quickly No joins, queries optimized for this use Good thing to experiment with, might be useful

- 12. Cd Rv w oe e ie s “Synchronous” = Look over my shoulder at this code “Asynchronous” - Look at this code later, get back to me Use synchronous for immediate feedback on small things Async for everything else Async allows for more thought, better record of comments
