SIENA NIST SIENA’s objectives are complementary to the role of the US National Institute of Standards and Technology (NIST) in cloud standards, guidance and technology. NIST partners with the EC and SIENA specifically in these areas. SIENA & NIST have developed a working relationship to help exchange efforts in common needs, recommendations and next steps.


NIST, the National Institute of Standards and Technology, is a bureau in the US department of commerce whose aim is to promote 0eb43222-c17e-4851-b88d-92d9f3f98dcdU.S. innovation and industrial competitiveness by advancing measurement science, standards, and technology. NIST developed a Cloud Computing Programme which is part of the general US Federal Cloud computing Strategy and whose main goal is to accelerate the federal government’s secure adoption of cloud computing .

NIST cloud computing programme

The objective of NIST is to provide a direction for US government CIOs to initiate any new ICT investments concerning cloud applications, thus helping CIOs and their agencies to identify interoperability, portability and security requirements  to adopt cloud computing. The chosen methodology encompasses a strategic and a tactical programme. Contributions of specific working groups, such as the SAJACC – Standards Acceleration to Jumpstart the Adoption of Cloud Computing help the drive towards the adoption of Cloud Computing.

NIST Strategic programme processes:

  1. To define target US cloud computing business use cases.
    i.e. how to implement cloud for weather warning information – which are the requirements and the possible  commercial solutions

  2. To define a neutral cloud computing reference architecture and taxonomy thanks to the inputs provided by industry
    The goal is to provide an extension of the US general cloud computing definition which is not linked to a specific provider

  3. To exercise the scenarios against the reference architecture to identify gaps
    The results of this activity will lead to the US cloud computing  technology roadmap

NIST Standards Acceleration to Jumpstart the Adoption of Cloud Computing (SAJACC)

The goal of the SAJACC initiative is to drive the formation of high-quality cloud computing standards by providing worked examples showing how key use cases can be supported on cloud systems that implement a set of documented and public cloud system specifications. The SAJACC initiative will develop and maintain a set of cloud system use cases through an open and ongoing process engaging industry, other Government agencies, and academia. Simultaneously, the SAJACC initiative will collect and generate cloud system specifications through a similarly open and ongoing process.
The SAJACC initiative will develop tests that show the extent to which specific use cases can be supported by cloud systems that implement documented and public cloud system specifications, and will publish test results on the SAJACC web portal.


“Implementation and deployment need to be in parallel with the development of standards, building on experiences and a knowledge base with testing along the way as standards evolve”.
Dawn Leaf, NIST, Senior Executive for Cloud Computing

In May 2011 NIST produced a further iteration of their draft Cloud Computing Synopsis and Recommendations broken into five groups: Management, Data Governance, Security and Reliability, Virtual Machines, and Software and Applications. Since then the first version of the Cloud Computing Standards Roadmap has been published.

SIENA and NIST, share the same objectives of producing a roadmap on the adoption of technologies that help the rapid spread of services. The findings of the NIST SAJACC group and the related use cases are relevant for the SIENA roadmap. The well-defined program of NIST should be used as a reference mechanism to identify requirements and gaps related to the provision of research and government e-infrastructures.

SIENA has established strong ties with NIST including participation of Dawn Leaf, Senior Executive for Cloud Computing, at Cloudscape-III, face-to-face meetings and regular participation to SIENA REB meetings. Participation by REB members at NIST events has also helped to strengthen ties between SIENA and NIST and to aid collaboration.
