The document discusses various options for hosting web applications in the cloud, including Platform as a Service providers like Google App Engine and Heroku, as well as do-it-yourself options using virtual private servers. It then introduces Hostout and Silverlining as tools that use the Buildout framework to deploy applications to remote servers, allowing code to be built and deployed automatically from a single configuration. Hostout uses Fabric scripts while Silverlining provides predefined server environments, and both are presented as alternatives to manually copying code for each deployment.

Opps i deployed it again
- 1. Oops! I deployed it again New ways to get your app in the cloud Dylan Jay
- 2. You've written a web app And now you need a host
- 3. We want it to be easy
- 5. We want it to be cheap
- 6. Options Type Providers Flexibility (Easy) Scalability Shared Few e.g. Webfaction ($14) Limited Choice (Control Panel) None AppEngine One Google (Free) No Choice (Launcher) Built in VPS Lots e.g. Slicehost ($20) Unlimited choice (DIY) DIY Cloud Few e.g. Rackspace ($11) Unlimited choice (DIY) DIY
- 7. Can you have your cake and eat it to?
- 8. Hostout (Fabric, buildout) & Silverlining
- 10. Push vs Pull
- 11. Fabric << fabfile.py >> from fabric import api def host_type(): api.run('uname -s') $ fab -H localhost,linuxbox host_type
- 12. Buildout Workflow Get the “buildout” $ python bootstrap.py $ bin/buildout $ bin/myinstalledscript … add recipes to buildout.cfg from pypi … $ bin/buildout
- 13. Building myapp $ bin/buildout $ bin/paster serve src/myapp/myapp.ini
- 14. Useful recipes zc.recipe.egg – download eggs and create scripts
- 15. collective.recipe.command – run shell commands
- 16. collective.recipe.template – make config files from templates
- 17. zc.recipe.cmmi – compile, make, install stuff
- 18. isotoma.recipe.apache – or any other useful shortcuts
- 19. mr.developer – manage source control
- 20. Hostout Is a buildout recipe to replicate a local buildout to many hosts (using fabric)
- 21. Hostout Get a “production” buildout
- 22. To your develop.cfg buildout add...
- 23. [myhost]
- 25. extends = hostout.cloud hostout.ubuntu
- 27. key = myaccount
- 30. $ bin/buildout
- 31. $ bin/hostout myhost deploy
- 32. Hostout is modular Collective.hostout Deploys buildout to any posix host. Needs IP and password hostout.ubuntu bootstraps ubuntu host for buildout hostout.cloud Creates node ready to be bootstrapped fabfiles = myfabfile.py – add your own
- 35. $ bin/hostout host deploy
- 36. Silverlining By Ian Bicking
- 37. Create app layout/dir $ silver init myapp Install dependencies into dir $ cd app; bin/easy_install repoze.bfg Install your code into dir $ bin/python src/myapp/setup.py develop
- 38. Silverlining II Configure it Edit app.ini: runner = src/myapp/myapp.ini Create host $ silver create-node myhost
- 39. $ silver setup-node myhost Deploy (rsync) $ silver update myapp --node myhost
- 40. Hostout vs. Silverlining Many deployers Checkin. Checkout. Buildout. deploy Hostout uses fabric Cross platform but more dependencies (pycrypto) Hostout is modular Package your own fabfiles to help others deploy Hostout is flexible – helps professionals Buildout is powerful. No limit to building/installing. NoSQL etc. Buildout shares dl code
- 41. Silverlining vs. Hostout Silverlining is batteries included You don't need a production buildout Silverlining is “known” target platform means less variables to go wrong Familiar workflow Commandline vs cfg.
- 42. Thanks Dylan Jay

Editor's Notes
- #13: Isolated environment Combine eggs, sdist, cmmi, .cfg, php, whatever Recipes do the combining Flow is Configure, build (auto install), run Vs Install, configure, run Can share “buildouts”
