In the IT enduser community, the idea of Open Source brings with it a plethora of elation as well as fear. Ask anyone who is an IBM AS/400 and they will tell you that they are stuck in their for life – at least until they decide to get out of what they put themselves into.
Yes, IBM AS/400 (rebranded as IBM System i in 2006 and subsequently replaced by the IBM Power System line) is a very stable platform. The many applications developed for it are rock solid, enterprise-class software that do what they are meant to do. Throughout its period of reincarnation (1988 to present), the hardware and software may have changed but IBM made sure the applications are transplanted.
I am digressing so let me paraphrase one CIO comment about their AS/400 investment. “We are stuck and we know we are paying through the nose but we have no alternative today!”
Distributed Computing (DC) arose partly in response to the need to get out of the mainframe and mini-computer era of vendor lock-in. Little did we know that while DC hailed the arrival of an army of vendors offering competing and complementary systems, the liberation was partial – because many of the initial technologies created in support of DC are proprietary in nature. Sure they are able to talk to other vendor’s solutions but this is because application programming interface (API) were built to allow for some semblance of interoperability.
Enter Open Source. The idea that a program’s code is freely available to the end-user community to use and modify to suite a particular need. Can a software company survive giving away its software? Red Hat thinks so. In fact, within the Open Source community, Red Hat is a testament to the idea that you can give away copies of your software (even if it was originally conceived by someone else), make money and prosper.
SUN Microsystems is another company that is heavy into the Open Source momentum. But whereas RedHat is 100% open source, SUN still has technology that is proprietary – afterall, SUN started life in the proprietary world. It can be argued that JAVA was SUN’s first experiment in Open Source. Thankfully, the JAVA community thrives today despite competition.
As with all things, proven or otherwise, there are skeptics. In human nature, the biggest fear is always that of the unknown. For many enterprises whose businesses depend on the smooth running of mission-critical applications, the high price associated with proprietary hardware, middleware or operating systems, custom application, and availability of skilled resources is a bitter sweet pill that they’d readily swallow.
