OWF13 - Multiple Clouds and multiple interest communities
0 likes283 views
This document discusses challenges in developing open-source software for cloud computing through collaborative projects. It describes two types of platform-as-a-service (PaaS) models and notes that open-source allows increased customization for some services but not full deployment control. Several European Union-funded projects are outlined that aimed to create open-source cloud middleware and address issues like licensing, standards, copyright and community building beyond the initial groups. Potential benefits of open-source PaaS include avoiding vendor lock-in, improving portability and lowering costs.

Deployment and hosting remains
on the provider site
Open source: increases the
service delivery over the traditional
form of software consumption
Through Clouds open-source
software can reach a new level of
maturity
