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

• IT infrastructure friction

• Focus on your core competences

• Focus on delivering value

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

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

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...

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
