The document discusses Stackato, a cloud-based platform as a service developed by ActiveState, focusing on the developer experience and deployment process using Perl and Mojolicious. It highlights features such as easy access to environments, one-click CLI deployment, and support for multiple targets including development, testing, and production. The author expresses enthusiasm about Stackato's potential to enhance infrastructure while minimizing discrepancies between different operational stages.

1. Stackato
- a developers experiences and evaluation
by jonasbn for Nordic Perl Workshop 2012,
Stockholm, Sweden

2. Disclaimer
• I am jonasbn - like almost everywhere
• Long time Perl and web developer
• Open Source/CPAN contributor and
previously freelance developer in logicLAB
• Currently employed with DK Hostmaster
• I have no affiliation with ActiveState

3. (My) Developer Needs
• Easy access to platform, runtimes and
frameworks
• The least possible gap between
development, test and production
• Minimal differences between deployed
code and the code in the editor
• reproducibility for transparency

4. What do we have?
• Unit-tests
• Mocked objects and classes, stubs a.s.o
• Local servers / emulators
• Virtualization
• Dedicated environments (dev/test/prod)
• Code - lots of code...

5. complexity
• We require magic
• We rely on tribal knowledge
• We need to jump through hoops

6. the Cloud
• What is the cloud?
• What problem does the cloud solve?
• What needs does the cloud address?
• So what is the cloud?

11. Dr. Matt Wood / 30%

12. Points from Dr. Matt Wood
• 30-70% divide
• IT infrastructure friction
• Focus on your core competences
• Focus on delivering value

13. Amazon EC2
• Amazon EC2 however does not get us
there - no matter how much elasticity it
provides
• http://aws.amazon.com/

14. JS/Ruby/Perl in the cloud?
• @ActiveState introduces #stackato
based on phenona and Cloud
Foundry
• http://www.activestate.com/stackato
• http://www.cloudfoundry.com/

15. Stackato
• A micro-cloud
• current version 2.2.3
• released 2012.02.29
• Platform as a Service (PaaS) private and
public
• Supporting several languages, their
frameworks and commonly-used services

17. Hello World!
first demo: in Perl using Mojolicious

18. recap
first demo: in Perl using Mojolicious

19. initial deployment
• target, where do we want to deploy
• login, it is all a matter of permissions
• push, a “one-click” CLI deployment
• stackato.yml - a configuration file for
assisting deployment
• stackato -n ...

20. inspecting deployment
• logs, our classical log files
• crashes, possible crashes
• crashlogs, and their logs
• files, our sandbox
• files app, our application

21. operating
• start, start a service
• stop, stop a service
• restart, restart a service
• this is about it, for what I can provide for
now, I have no experience with long time
operation of a Stackato deployed service
• Oh there is one more thing...

22. Demo 2

25. updating
• update, when an application has been
pushed (deployed) this is the command you
will use...
• Or you can integrate with your IDE and
possible other tools in the future, more on
this later...

26. All the little things
• binding DNS, going beyond mDNS
• binding services (databases et al.)
• resource allocation, memory, instances etc.
• logging (more on this later...)
• now for some high-level architecture...

28. Support
• @ActiveState fora
• #stackato on irc://irc.freenode.org with
users and ActiveState staff
• Webcasts + white papers
• ActiveState are incredibly open and
cooperative

29. Open Source Examples
• @ActiveState examples on Github
• my own fork is on Github
• Github is nice!

30. Stackato is not... or?
• Open Source? - it is closed and proprietary
• @ActiveState is however dedicated to
keeping the micro-cloud solution free
• the command-line client stackato is open
source and available on Github

31. So what is in it?

32. Targets!
• Multiple targets
• development / test / production
• Targets make sense in SCM context
• trunk / branches / tags (releases)
• You could just go for the micro-cloud, but
you would loose some of the benefits

34. But wait there is more!

35. Demo 4
the built in app store

36. App Store
• Simply a matter of configuration
• Your complete application portfolio one
click away
• Operations - go shopping!
• https://github.com/ActiveState/stackato-
app-store

37. My Current Road Map
• Oracle as a service (Perl driver DBD::Oracle and Oracle driver
distribution issue) works!
• Cryptographic components (export of PPMs, Perl packages) works!
• Deployment of custom components works!
• Full blown examples (Mojolicious over Mojolicious::Lite etc.) works!
• Central logging (syslog) works!
• Service integration (PostgreSQL) works?
• mDNS and dynamic DNS (might be .local)

38. Conclusion
• The Stackato cloud is awesome
• @ActiveState mean serious business
• I am going to present and propose Stackato
as a part of our future infrastructure

39. Benefits
• Easy and controlled access to platform,
runtimes and frameworks
• The least possible gap between development,
test and production and minimal differences
between deployed code and the code in the
editor depending on your cloud deployment
• reproducibility for transparency since the
amount of magic is kept at a minimum
