The document is about an upcoming presentation on open source alternatives to proprietary software. It discusses what open source software is according to the Open Source Initiative, important open source licenses like BSD and GPL, and examples of widely used open source applications and platforms across various categories like operating systems, virtualization, databases and middleware. The examples are intended to illustrate the viability and adoption of open source software but no endorsement of any particular option is implied.

being
the

reviewing
and
approving
licences
as
OSD
conformant.

Why
open

• No

If

there
is
nothing
to

• Open
