I’m tired. Tired of hearing yet another big bozo speech about how we will move to open source and how that will magically reduce our costs and make our software better.
Gentlemen (and those few ladies who end up reading this), behold, a couple of reality checks
1. Open source is not free
Contrary to popular belief, open source comes at a cost. Unlike commercial packages (full software, or libraries) the cost here is not tied to the initial cost of acquisition (either as a license fee with or without a support contract). The true cost of open source hides at a deeper level. The place where it still costs money is a cost of integration. Even though the idea of open source is that there are a whole slew of people working on it and that the community will be the best support group ever, the reality is that a lot of open source projects are actively maintained by only a handful of people per project. Which generally means that you (the developer who needs to integrate it) will spend a lot of time reverse engineering the code.
The second point where there is a form of (rather indirect) cost attached is in the area of strategy and maintenance. Since this code is created and maintained on a voluntary basis it doesn’t really carry any form of guarantee that it will be maintained and/or evolve, and if it does evolve in a direction that might not be what you wish/expect, there is no sales/account/technical staff to help you out in the migration or to voice your concerns to.
2 The licensing aspect
There is a vast number of licenses out there, making the distinction between all of them is beside the point here. Suffice to say that, in general, there are a number of common themes.
Not everything can be used for commercial purposes, some might require that you submit any modification back to the community under the same license, some allow you to use it as if it were closed source, … . Best to have your legal people look at the license if you are unfamiliar with the matter. Just a point of attention…
In conclusion, yes I believe open source code can make your software better but there is an amount of sanity checking that needs to be done (just as we do with closed source). The questions to be asked are not just a matter of financial or legal cover-your-ass but also of strategy (do I like where this thing is heading?, do I want this vital piece of my software to be open source?). There is no one-size-fits-all answer to these questions, so let us please answer them and do the due diligence.
