ITIL: Open Source vs. Commercial

As ITIL continues to gain converts, more and more support software is becoming available. Which is better open source or commercial? The debate continues.

Open source is once again being hailed as a cheap and efficient bandage for companies hemorrhaging from a weakened economy and wounded budgets. Open source promises a big bang for precious few bucks, at least on the front end. But is "cheap" enough of a reason to ditch commercial ITIL solutions?

The answer extends beyond the philosophical differences of the open source vs. commercial camps. For one thing, not all open source software is created equal therefore not all open source products will score the same.

“I could program an ITIL solution in one week and provide it for open source download and it would be worthless,” said Chris Drake, founder and CEO of FireHost, a hosting company. The problem lies in the lack of a large community base to support the solution. To gain any advantage from open source, IT needs to learn the solution on its own, find a service firm to help, or rely on the community for support, making up-time requirements a prime consideration.

Another advantage in popular open source solutions: they carry a bucket-load of features, often exceeding that of commercial offerings. The best solutions, said Drake, provide only the framework and allow the community to extend the solution. “Nagios is a perfect example,” he said. “The community has gone wild and has extended the solution more than any commercial solution available. Hence, they’re the post popular monitoring solution.”

While open source solutions can have as much as 10 times the features of commercial products, more is not necessarily better. It is relatively easy to get lost in the maze of features and the customization processes. Alternately, commercial solutions can also be too huge for recession-pruned IT teams to manage and too stiff to customize for a company’s exact needs; all leading to waste in terms of cost and time. Customization can be overdone too. The key kink in the code chain comes from immature ITIL processes.

“Implementing open source software in a case where the ITIL culture is not yet strong enough may cause an over-customization of the tool and thus cause the main objective of implementing ITIL to be distorted,” said Alejandro Montini, manager of IT Infrastructure at Globant. By comparison, a solid commercial software offering can greatly help in streamlining and speeding the initial implementation of ITIL while avoiding deviations from the standard, he said. Oddly, even though Globant specializes in using open source software, Montini said he would “dedicate all efforts to improving the overall quality of the company's services based on ITIL and I would select a commercial ITIL software to support this objective."

The biggest differentiator between open source and commercial ITIL solutions remains security. While commercial applications have their own vulnerabilities “it’s much tougher to find those holes as the source code isn’t available,” said Drake. With open-source, the hackers can download the same source code and look for vulnerabilities or poorly written code from within the inside of the software. Heavily regulated industries will probably steer clear of open source solutions for fear of heavy penalties should a breach occur. It is hard to construct a winning court defense when the potential threat is known and well-documented in advance of deployment.
