Reference Architecture Is Perfectly Aligned with Open Source
• Reference Architecture enables a
decomposed model … implement
best of breed components in vendor
neutral manner…
• Breaking … into components …
implement features … in gradual
ways that track demand
• Each campus must be capable of
bidirectional SIP … as the primary
communication protocol
QuickTime™ and aTIFF (Uncompressed) decompressor
are needed to see this picture.

The Open Source Trend
• Starting to gain market currency
• .edu attracted by the same benefits associated with other
open source software
- Disaggregation and flexibility that favors customers
- Open, flexible framework based on SIP
- Lower prices; ongoing downward pressure on prices
- Faster development cycles & more innovation at every level
• Can open source become enterprise class and really
change the market?

Open Source Myths & Reality
Myth Reality
Open source is a security risk because anyone can contribute (malicious) code
Open source projects are closely managed by “project maintainers” that control commit access and inspect all submissions
Open source is lower quality because no one makes money from it
Open source code gets large scale review by SMEs before check-in. Commercializers contribute SQA
Open source means self support making it more expensive/impractical to use
Most open source is available as a supported product; management tools now very good; plug & play
The real issues are (software) maturity and availability of commercial version
