Beyond the Cloud: Cyberphysical Systems
- Authors: Hurlburt; George;Voas, Jeffrey;
  Pages: 2 - 4
  Abstract: Although clouds don't freely interact with fellow or competitor clouds today, this is likely to change, leading to larger networks of collaborative, autonomously operating clouds, each optimized for specific services. As this happens, we'll need a framework for understanding this dynamic, nonlinear space representing various networks. Graph theory and the concepts underlying cyberphysical systems can help.

Government Risk Management Lags behind Vendor Practices
- Authors: Anderson; Julie M.;
  Pages: 5 - 7
  Abstract: Current US law and government IT policy take a limited a view of the potential conflicts between existing government information privacy and security standards and actual vendor data collection practices. As a result, procurement requirements lack appropriate risk-management and enforcement mechanisms. Given the proliferation of data collection practices in Internet services companies, government IT leaders should more directly define the parameters of government data ownership in government IT policy and procurement guidance. Government should also better educate employees and govern the use of Internet-based services on government-owned systems.

Medical Records and Software Trust
- Authors: Larson; David;Miller, Keith W.;
  Pages: 8 - 11
  Abstract: The rapidly growing use of medical software raises many ethical and privacy issues. This column builds on a previous IT Ethics column, which presented a model of trust focused around software. The authors map out different trust relationships that exist between stakeholders in medical record automation to master the trust issues in this complex sociotechnical system.

Cloud Computing
- Authors: Bojanova; Irena;Zhang, Jia;Voas, Jeffrey;
  Pages: 12 - 14
  Abstract: Cloud computing is no longer on the horizon; it has become the next logical step for the IT industry. It's the new strategic weapon in enterprise computing and the new norm in every sector of society. Businesses, educational institutions, governments, community organizations, and individuals are looking at cloud offerings to manage information instead of infrastructure. In this issue, the theme articles discuss migration performance, energy-efficiency enhancement, and security issues in cloud computing.

Solar-Powered Cloud Computing Datacenters
- Authors: Hosman; Laura;Baikie, Bruce;
  Pages: 15 - 21
  Abstract: In the developing world, reliable and affordable electricity isn't always available, presenting challenges for the Western "bigger is better" datacenter model. A small-scale, cloud computing datacenter, however, could leverage recent technological breakthroughs to instead rely on solar energy.

The Insecurity of Cloud Utility Models
- Authors: Idziorek; Joseph;Tannian, Mark F.;Jacobson, Doug;
  Pages: 22 - 27
  Abstract: Cloud-based services are vulnerable to attacks that seek to exploit the pay-as-you-go pricing model. A botnet could perform fraudulent resource consumption (FRC) by consuming the bandwidth of Web-based services, thereby increasing the cloud consumer's financial burden.

Energy-Efficient Virtual Machine Consolidation
- Authors: Graubner; Pablo;Schmidt, Matthias;Freisleben, Bernd;
  Pages: 28 - 34
  Abstract: A novel approach to virtual machine (VM) consolidation, based on energy-efficient storage migration and live VM migration, is implemented using Eucalyptus, an open source clone of the Amazon Elastic Compute Cloud. Several experiments demonstrate the potential energy savings.

Using Model Checking to Evaluate Live Migrations
- Authors: Kikuchi; Shinji;Matsumoto, Yasuhide;
  Pages: 36 - 41
  Abstract: Server virtualization technologies and their live migration function support more efficient use of computing resources in cloud datacenters. However, many management operations for virtual machines can be evoked simultaneously in large-scale systems. What happens if many live migrations are executed simultaneously?

A Digital Signature Architecture for Web Apps
- Authors: Ponnapalli; Harigopal K.B.;Saxena, Ashutosh;
  Pages: 42 - 49
  Abstract: This digital signature architecture provides browser-agnostic, client-side signature components and generic server-side signature validation components to help integrate signatures into Web applications. The authors also discuss ways to extend HTML syntax to support signatures.

Micropreneurs: The Rise of the MicroISV
- Authors: Thackston; Russell;Umphress, David;
  Pages: 50 - 56
  Abstract: Micro Independent Software Vendors (microISVs) are small software businesses operated by entrepreneurs who build and sell shrink-wrapped, noncustom software. The microISV Research Alliance at Auburn University conducted a survey, identifying challenges associated with building and operating such businesses.

Courses for the Masses?
- Authors: Laplante; Phillip A.;
  Pages: 57 - 59
  Abstract: Massively open online courses (MOOCs) promise free, high-quality, university-course content to anyone with Internet access, but in reality, they're no substitute for credit-bearing university courses.

Why Is IT Still Broken?
- Authors: Costello; Tom;Prohaska, Beverly;
  Pages: 64 - 64
  Abstract: Why hasn't IT delivered the promises envisioned 20 years ago? Some likely culprits include uninformed business management teams, poor project and portfolio management, low participation from business executives and sponsors on IT-enabled business projects, and an ill-prepared multigenerational workforce. The authors examine these four potential problem areas and highlight solutions for improvement.
