NIST Cloud Computing & Big Data Forum, Jan 15-17 2012

NIST Cloud Computing & Big Data Forum, Jan 15-17 2012

On the second day of the NIST Cloud Computing & Big Data Forum, we had a real treat...the keynote speaker was Vint Cerf, Google's VP and Chief Internet Evangelist. Allocated a mere 30 minutes, he actually spoke for more than 45, detailing his thoughts on Cloud Computing, Big Data, and related topics. He highlighted some of the security issues concerning cloud computing, like the problem of "leftovers" (data remaining after a virtual service has been deprovisioned), and the need for strong authentication of both user identities and trusted identifiers. He also emphasized the need for non-proprietary inter-cloud communication and collaboration protocols, and mentioned a bit about Google's cloud services including a comment about their current 100Gb OpenFlow-based infrastructure and their potential need for Terabit connectivity in their data centers.

One interesting Big Data comment he made concerned the problem of feeding data fast enough into today's powerful multicore processors, and suggested the memristor as a possible technology solution.

Later in the conference at a panel on Big Data Use Cases, Veterans Affairs CTO Peter Levin gave a briefing on the VA's Blue Button system for accessing veterans' health care records, and its potential to grow to thousands of terabytes as genetic data is included, just one of many examples of Big Data projects discussed today. Presentations from the conference will be posted on the NIST Cloud Computing Web site.

Clouds Aroud the World

At the NIST Cloud Computing Workshop this week; representatives from Canada, China, and Japan presented on their cloud computing efforts. Some interesting points made:

Canada: Building "Service Canada" cloud for all citizen services, but raised the issue of data data must be within Canada border, so they will not focus on public clouds where they don't know or can't control data location.

Japan: In response to the massive destruction of the Great East Japan Earthquake, Japan is building nation-wide cloud services to support disaster relief, data recovery, and support for rebuilding new communities.

US Ambassador Philip Verveer discussed the need for international cooperation and standards development to enable interoperability of cloud services, keeping in mind cultural and political differences. Additionally, an industry panel reported on cloud standards development, including some actual interoperability testing at Much of the first two days of the workshop covered progress and action plans around the 10 High-Priority Requirements to Further USG Agency Cloud Computing Adoption.

Thursday's sessions will cover the work of the various NIST Cloud Computing Working Groups on

  • Reference Architecture and Taxonomy
  • Standards Acceleration to Jumpstart the Adoption of Cloud Computing (SAJACC)
  • Cloud Security
  • Standards Roadmap
  • Business Use Cases

(see Working Groups of NIST Cloud Computing )

The NIST Cloud Computing Forum & Workshops IV (Nov 2-4, 2011)

The new US CIO, Steve Van Roekel, along with senior researchers at NIST, hosted the fourth Cloud Computing Forum and Workshops this week ( ). One highlight was the release of the Draft Cloud Technology Roadmap with a call for public comments. See the Web site for the agenda and downloadable documents and presentations.

There were international participants at the event, with much friendly discussion of "openness", "interoperability", and an idealistic "One Cloud" vision of a "Cloud Without Borders". A very hopeful perspective, but perhaps a bit overly optimistic one given the current political state of the world and various governments' control of Internet access and resources.

One issue that concerns me in all this rush to cloud computing is the question of where the expertise will come from to design, build, and manage massive cloud infrastructures? Concepts such as parallel programming, scalability, virtualization, and cache management need to be integrated into CS curricula from the start, maybe even starting in high school but certainly at the undergraduate level. I don't yet see sufficient emphasis on those areas in the CS courses and textbooks offered by many universities. Without a continuous stream of knowledgeable graduates, the lack of cloud computing experience and expertise will slow the adoption of this transformative technology.

Security and trust in the cloud remain primary concerns; the NIST Cloud Computing Security Working Group has released a draft publication outlining 17 key requirement areas for cloud security ( ). Yet in spite of the current lack of mature security solutions and interoperability/development standards, it was still recommended that agencies start their cloud deployments with the expectation that expertise will evolve through experimentation, trial, and (inevitably) error.


The purpose of this blog is to highlight and to explore general issues around "Cloud Computing" -- its benefits, risks, and component technologies -- and how they are evolving. I'll also periodically comment (of course!) on Oracle's Cloud Computing capabilities, resources, and cloud-related events. -- Harry J Foxwell, PhD, Principal Consultant for Cloud Computing, Oracle Public Sector HW
