Sales of open source software will grow from $1.8bn last year to $5.8bn in
2011, analyst firm
IDC predicts.
Matt Lawton, programme director for IDC's Open Source Software Business
Models research programme, typified the current market as "immature" and in the
"early stages".
The projected revenue figure is low when compared to commercial, closed
source software. But the analyst believes that revenues alone do not reflect the
actual distribution of open source software.
Proprietary software typically charges an upfront fee, while open source
charges only for support and typically does so on a pay-as-you-go basis.
IDC cited culture and comfort levels as the primary drivers behind open
source software.
The development model has gained credibility because venture capital
investors are increasingly backing the software.
Companies have become more comfortable with subscription models such as those
pioneered by
Red Hat.
