Among the considerable benets of
open source technology is that it is
vendor agnostic, so it can be interfaced
readily with existing legacy systems.
Open source solutions allow the
physical footprint to be more precisely
engineered and t for purpose.
Therefore, the actual implementation
is very small and keeps disruption to a
minimum. In addition, the costs
savings can be huge.
More broadly, open source
communities focus on innovation and
collaboration. This has changed how
the big vendors are thinking, with
Google and Microso‰ already now
leading the open source revolution.
