A declaration of core principles for cloud computing providers. Introduced in 2009 and endorsed by hundreds of hardware and software companies, the Manifesto was created to promote the use of open standards by cloud providers. For more information, visit www.opencloudmanifesto.org. See cloud computing. The Core Principles of the Manifesto 1. Cloud providers must work together to ensure that the challenges to cloud adoption (security, integration, portability, interoperability, governance/management, metering/monitoring) are addressed through open collaboration and the appropriate use of standards. 2. Cloud providers must not use their market position to lock customers into their particular platforms and limit their choice of providers. 3. Cloud providers must use and adopt existing standards wherever appropriate. The IT industry has invested heavily in existing standards and standards organizations; there is no need to duplicate or reinvent them. 4. When new standards (or adjustments to existing standards) are needed, we must be judicious and pragmatic to avoid creating too many standards. We must ensure that standards promote innovation and do not inhibit it. 5. Any community effort around the open cloud should be driven by customer needs, not merely the technical needs of cloud providers, and should be tested or verified against real customer requirements. 6. Cloud computing standards organizations, advocacy groups and communities should work together and stay coordinated, making sure that efforts do not conflict or overlap.
