Tracing The Evolution Open Source & Embedded Systems - Mr. Jayakumar Balasubramanian,Director at Emertxe Information Technologies

  1. 1. “Tracing the Evolution” Open Source & Embedded Systems Jayakumar Balasubramanian Director, Emertxe Information Technologies b.jayakumar@emertxe.com Presented at Lounge47.in 8th March 2014 Copyright @ Mr. Jayakumar Balasubramanian, Emertxe
  2. 2. Some motivation.. Personal experience:  Install, Crash, re-install, Crash – “Dorm-room” experiences!  “Migration to Linux” – Lingering over a decade now  Its everywhere – Device, Pipe and Cloud services Viewpoint:  Open Source & Embedded products – Builder’s view  Lab prototype v/s mass production – How different or same they are?  Managing open source with open source – Recursion?
  3. 3. Tracing the evolution - Open Source
  4. 4. How it all started?  With GNU (GNU is not UNIX)  Richard Stallman made the initial announcement in 1983, Free Software Foundation (FSF) got formed during 1984  Volunteer driven GNU started developing multiple projects, but making it as an operating system was always a challenge  During 1991 a Finnish Engineer Linus Torvalds developed core OS functionality, called it as “Linux Kernel”  Linux Kernel got licensed under GPL, which laid strong platform for the success of Open Source  Rest is history!
  5. 5. How it evolved?  Multiple Linux distributions started emerging around the Kernel  Some applications became platform independent  Community driven software development started picking up  Initially seen as a “geek-phenomenon”, eventually turned out to be an engineering marvel  Centered around Internet  Building a business around open source started becoming viable  Redhat set the initial trend in the OS business Kernel Applications Customization
  6. 6. Where it stands now? OS Databases Server/Cloud Enterprise Consumer Education CMS eCommerce
  7. 7. Business models Consulting & Support • Charge for specific consulting service offering • Technical installation, customization and support Dual License • Distribution under two sets of terms and conditions • Community and Commercial editions Partner program • Developer/Partner ecosystem • Hosted as a platform Donations • Address a non-commercial need • Create a donation system and raise funds
  8. 8. Licensing blues..  Copyright and Copy left  GNU General Public License (GPL)  Freedom to run, copy, distribute, study, change and improve  (“Free” = “Freedom”) != “Free Beer”  Commercial distribution  Reciprocation  Derived work
  9. 9. Inflection Point – Linux Kernel
  10. 10. Kernel history
  11. 11. Embedded + Kernel  Non x86 architectures in Embedded Systems  Secure and portable monolithic architecture  Supports multiple instructions (ARM, MIPS, PPC etc…) – ideal for Embedded  Quality and reliability of code  Communication protocols and software standards  Cost and Time-to-market advantages  Vendor independence
  12. 12. Engineering marvel * Source: Linux foundation report, 2013
  13. 13. Why so?  Product features into Kernel, wider adaption  Higher interest from semiconductor companies  Global development model, leveraging talent  Influencing ability  Organizational brand Bottom line: It no longer a geek phenomenon. Can’t afford to miss this any more
  14. 14. Embedded products using Open Source
  15. 15. Three aspects Build  What do I want to build? How am I doing to build?  How to I test and qualify the product? Qualify  How to I manage the product and release to my customers? Manage & Release • Building ‘lab prototype’ is different from ‘mass manufacturing’ • Application product building doesn’t suite Embedded
  16. 16. Step-1 : Build Choice Points • • • • • Which version of Kernel? Which development environment? Tool chain Drivers and binaries Support and training Key actions: • • • • • Download Kernel: http://www.kernel.org Develop BSP (if required) Build the image (Use Build-root or Yocto) Add custom functionality Development & Coding
  17. 17. Step-2 : Qualify Code & Build Code quality Secure & Scale Automate Diagnostics Test
  18. 18. Step-3 : Manage Project Mgmt Bug tracking Collaboration Right from setting initial code base, open source tools are available for develop, Qualify and release the final product. There are very useful product/project management tools available to easily manage it.
  19. 19. Closing notes..  Its no longer a “geek phenomenon”!  For new product ideas all of us (engineers, enthusiasts and entrepreneurs) can rely on Open Source and its associated ecosystem  Excellent product/project management tools are available to monitor, track and launch commercial Embedded products  Qualification is a very mature area in Open Source, which MUST be leveraged  Obvious benefits in terms of – Cost, Time-to-market, Support and a sense of contribution
