Stackato v5

Stackato- a developers experiences and evaluationby jonasbn for Nordic Perl Workshop 2012, Stockholm, Sweden

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

(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

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...

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

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

Talking Cloud You cannot ignore Amazon and EC2

Dr. Matt Wood (@mtz)• Technology Evangelist with Amazon, working with Amazon Web Services (AWS)• http://youtu.be/NT-ccnFMBWA• from Internetdagarna 2011 in Stockholm/ Sweden

Dr. Matt Wood / Heavy Lifting

Dr. Matt Wood / 30%

Points from Dr. Matt Wood• 30-70% divide• IT infrastructure friction• Focus on your core competences• Focus on delivering value• http://www.slideshare.net/FDIHdk/ahead-in- the-cloud-matt-wood-amazon

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

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

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

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 ...

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

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...

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...

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...

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

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

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

So what is in it?

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

But wait there is more!

Demo 4the built in app store

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

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)

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

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
