DoD Turns to Cloud Computing

Wednesday, May 26th, 2010

The DoD wants to tap into the benefits of cloud computing. In May 5/09 testimony [pdf] before a US House panel, Pentagon cybersecurity official Robert Lentz offered the following prediction about the benefits of cloud computing for DoD:

“A cloud is…an ideal place from which to make capabilities available to the whole enterprise. While, in the DoD, we have encountered challenges moving towards a service-oriented architecture (SOA), in the private sector, companies like Google and Salesforce are basing their business models on an insatiable public hunger for software and applications as a service. Emulating their delivery mechanisms within our own private cloud may be key to how we realize the true potential of net-centricity.”

According to the US National Institute of Standards (NIST), cloud computing has the following characteristics:

  • “On-demand self-service. A consumer can unilaterally provision computing capabilities, such as server time and network storage, as needed automatically without requiring human interaction with each service’s provider.

  • Broad network access. Capabilities are available over the network and accessed through standard mechanisms that promote use by heterogeneous thin or thick client platforms (e.g., mobile phones, laptops, and PDAs).

  • Resource pooling. The provider’s computing resources are pooled to serve multiple consumers using a multi-tenant model, with different physical and virtual resources dynamically assigned and reassigned according to consumer demand. There is a sense of location independence in that the customer generally has no control or knowledge over the exact location of the provided resources but may be able to specify location at a higher level of abstraction (e.g., country, state, or datacenter). Examples of resources include storage, processing, memory, network bandwidth, and virtual machines.

  • Rapid elasticity. Capabilities can be rapidly and elastically provisioned, in some cases automatically, to quickly scale out and rapidly released to quickly scale in. To the consumer, the capabilities available for provisioning often appear to be unlimited and can be purchased in any quantity at any time.

  • Measured Service. Cloud systems automatically control and optimize resource use by leveraging a metering capability at some level of abstraction appropriate to the type of service (e.g., storage, processing, bandwidth, and active user accounts). Resource usage can be monitored, controlled, and reported providing transparency for both the provider and consumer of the utilized service.”
