Stackato

Stackato- a developers experiences and evaluation by jonasbn for Open Source Days 2012

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

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...

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

Williamstown Theatre Festival?

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 The general issue of development vs. operations is quite wide- spread, see something like the GOTOCPH conference 2011 with• IT infrastructure friction a dedicated track• 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/

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 1.0.4 • just out of beta, released 2012.02.29• Platform as a Service (PaaS)• Supporting several languages, their frameworks and widely-used services

Hello World!ﬁrst demo: in Perl using Mojolicious

recapﬁrst demo: in Perl using Mojolicious

initial deployment• target, where do we want to deploy• login, it is all a matter of permissions• push, a “one-click” CLI deployment

Requirements• PPM (ActivePerl)• CPAN (App::cpanminus)• requirements.txt

Sandboxing• local::lib, encapsulates in a Perl sandbox • Your apps will not intrude on each other - unless you want them too

inspecting deployment• logs• crashes• crashlogs• ﬁles

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

Management Consolesecond demo: the built in management console

Hello Open Source Daysthird demo: in Perl using Mojolicious

recapthird demo: in Perl using Mojolicious

updating• update, when an application has been pushed (deployed) this is the command you will use• stackato.yml - a conﬁguration ﬁle for assisting deployment

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 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• Open Source - it is closed and proprietary • @ActiveState is however dedicated to keeping the micro-cloud solution free

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

My Current Issues• Oracle as a service (DBD::Oracle and driver distribution issue)• Cryptographic components (export of PPMs)• Deployment of custom components• Service integration (PostgreSQL)• Full blown examples (Mojolicious over Mojolicious::Lite etc.)• 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
