In
2011, Col. Timothy Hill, director of the Futures Directorate within the
Army Intelligence and Security Command, urged industry to take a more
open-standards approach to cloud computing. “Interoperability
between clouds, as well as the portability of files from one cloud to
another, has been a sticking point in general adoption of cloud
computing,” Hill said during a panel at the AFCEA International 2011 Joint Warfighting Conference.
Hill’s view has been echoed by many in the cloud computing community,
who believe that the absence of interoperability has become a barrier to
adoption. This posting reports on recent research exploring the role of standards in cloud computing and offers recommendations for future standardization efforts.

As
part of an ongoing effort to keep you informed about our latest work,
I'd like to let you know about some recently published SEI technical
reports and notes. These reports highlight the latest work of SEI
technologists in information assurance and agile, the Team Software Process (TSP), CERT secure coding standards, resource allocation, fuzzing, cloud computing interoperability, and cloud computing at the tactical edge.
This post includes a listing of each report, author(s), and links where
the published reports can be accessed on the SEI website.

We
use the SEI Blog to inform you about the latest work at the SEI, so
this week I'm summarizing some video presentations recently posted to
the SEI website from the SEI Technologies Forum.
This virtual event held in late 2011 brought together participants from
more than 50 countries to engage with SEI researchers on a sample of
our latest work, including cloud computing, insider threat, Agile
development, software architecture, security, measurement, process
improvement, and acquisition dynamics. This post includes a description
of all the video presentations from the first event, along with links
where you can view the full presentations on the SEI website.

Cloudlets,
which are lightweight servers running one or more virtual machines
(VMs), allow soldiers in the field to offload resource-consumptive and
battery-draining computations from their handheld devices to nearby
cloudlets. This architecture decreases latency by using a single-hop
network and potentially lowers battery consumption by using WiFi instead
of broadband wireless. This posting extends our original post
by describing how we are using cloudlets to help soldiers perform
various mission capabilities more effectively, including facial, speech,
and imaging recognition, as well as decision making and mission
planning.

The Department of Defense (DoD) is increasingly interested in having soldiers carry handheld mobile computing devices
to support their mission needs. Soldiers can use handheld devices to
help with various tasks, such as speech and image recognition, natural
language processing, decision-making and mission planning. Three
challenges, however, present obstacles to achieving these capabilities.
The first challenge is that mobile devices offer less computational
power than a conventional desktop or server computer. A second challenge
is that computation-intensive tasks, such as image recognition or even
global positioning system (GPS), take a heavy toll on battery power. The
third challenge is dealing with unreliable networks and bandwidth. This
post explores our research to overcome these challenges by using
cloudlets, which are localized, lightweight servers running one or more
virtual machines (VMs) on which soldiers can offload expensive
computations from their handheld mobile devices, thereby providing
greater processing capacity and helping conserve battery power.
