Green Code Lab Challenge 2014 - Green IT Applied To Public Works
- 1. Green IT applied to Public Works #GCLChallenge @willylambert
- 2. @willylambert Web & Mobile Developer Web App Angular JS Continuous Delivery Karma Selenium Docker 10 years in Clinical Trials Industry Since 2013 @ Luc DURAND Cartography Leaflet MapBox Open Data
- 3. Agenda Part #1 Part #2 IT for Green : How we use IT to reduce our environmental impact My Company : Part #3 Green for IT : How we build Green Apps
- 6. We extract rocks (aggregates)
- 7. ICI photo centrale bailleul We produce asphalt
- 8. We design & build water-treatment plant
- 9. We innovate
- 10. We promote circular economy
- 13. 12 592 078 Kms 2 897 000 liters of fuel (Truck & Machinery) 47 822 Tons of C02 …Maybe IT can help ? In One Year…
- 15. Paper-free answer to Request For Proposals 400 commercial offers / year Promote sustainable policies Reuse hardware Recycle papers and water bottles Reduce printing Eco Driving training Find a second life to old hardware IT for Green e.g. 5 years as Graphics Workstation then 2 years as Internet and Office computer
- 16. IT for Green Virtualize datacenters 30 virtual servers / 4 « reals » servers Use mobile technologies to leverage access to enterprise ressources Remote control of isolated weightbridge sites Access on the field to technical & administrative docs DEVELOP APPS
- 17. Cartography
- 18. Use Open Data fromdata.angers.fr
- 20. Just a small web app based on cloud services A green app ? No ;-( BUTIt reduces time It reduces travels
- 21. ITforGreen : Weightbridge The old way… 1 weightbridge = 1 operator on site delivery orders printed on paper On each site : • Computer(s) • 2 or 3 Printers • NAS (for backup) Digital Signed Weight, T° Order 3G
- 22. Choose The Right Tool
- 23. To have the job done effectively
- 24. Choose the right tool Apache or Nginx ? MySQL or SQLite ? XML or Json ?
- 25. Size smartly if I expect 5 simultaneous connections, I size my app for 50 connections, not 500 neither 1000 !

- 31. The Problem A classical n-tiers stack WEB SERVER APPLICATION SERVER DATABASE SERVER My Quick & Dirty* stack VS * Copyright @willylambert Maintainability Scalability Green + + + + Security
- 32. The Solution One Virtual Machine or Cloud Instance WEB SERVER CONTAINER APPLICATION CONTAINER DATABASE CONTAINER LOGGING CONTAINER TEST TOOLS CONTAINER • Resources provisioning • Turn on / off containers within seconds • Same environment in dev/test/prod • Consistent deployment everywhere BUILD TOOLS CONTAINER
- 33. 1. Match users expectations (not more) 2. Carefully choose tools and technologies 3. Size smartly 4. Monitor performance 5. Be dev-ops
- 34. « On ne sauvera pas la planète en se contentant de fermer le robinet après s'être brossé les dents » Dominique Voynet - 2006 Thank You
Editor's Notes
- Let's start by introducing myself
- Focus on web app involving maps Software industry like other
- 1 What we Do 2 Real example green way 3 Technical / Personal Part
- Mainly we build roads
- Quarries Activities (2 sites)
- Asphalt Production Plant
- Subsidiairies dedicated to
- Since the beginning faith in innovation
- First example not related to IT Scrap Asphalt - crush and filter
- 100 % of aggregates come from recycled asphalt
- Simple and Daily actions 60 % Customers = Collectivities – offers electronic plateform to collect proposals Fight obscelence
- Big Move by Virt Push on to Find Mobile Use Case to reduce usage of paper and reduce travels
- In Public Works We Love Maps
- Open Data offered by ALM Evacuation network of wasted water Raw Datasource => DataVis To give meaning => Interactive map
- Sorry ! Limits the need to go systematicly on the field.
- Sorry ! Limits the need to go systematicly on the field.
- #1 => Add remote control capabilities #2 => Paper Based workflow to a full electronic one involving a trust authority Green IT was a key in development. #3 => able to powerize the overall system with photovoltaic supply Now il will slide smoothly to the last part of this presentation : How we implements Green IT @ Luc DURAND
- First rule : Consciously Choose the best tool depending on the work you have to do
- All craftmen do that, and in a way we, developers, are craftmen.
- when I start a new project i ask myself
- Next rule : not too small, but not too large ! You remember my weightbridge ?
- Photovoltaic power up is possible because we have carefully sized the hardware
- I care a lot about performance : I like the concept of Performance Driven Performance
- I setup a Virtual Machine with limited ressourced Fiddler : bandwith & latency Time to time : Raspberry as a server PDD : Monitoring Performance, Selenium New version = more needed power mainly due to a lack of optimisation
- There is a last subject, that was not initially part of my presentation
- All in one approach Who wins ? We must admit that going to far on Green IT could conduct to unmaintainable and unsecure software This is for me an historical dilemma
- Docker brings a very smart and green solution I play with it since few days Isolation and consistency between dev and prod In a single cloud instance (or local VM)
