THE POWER OF CLOUD COMPUTING
Cloud computing adds five distinct advantages to the best features of data center computing. Resources can be shared between programs and used as needed—an improvement on the over- provisioning that occurs with data centers. (SOURCE: CIO/G-6 and Microsoft)
CLOUD SERVICE OFFERING
Additionally, the user experience becomes more consistent and less tech- nically complex, through a common set of applications and consistent end-user device interfaces, which reduces training requirements and costs. And capability enhancements are fielded much faster; with computing infrastructure available to research and development (R&D) com- munities through on-demand, self-service portals, there is no need to wait on long procurement cycles for R&D to begin enhancing capabilities. Te Army also can take advantage of the commercial R&D efforts that can readily be ported from and into the cloud.
WHAT THE ARMY IS DOING Hybrid cloud: Te Army Cloud Com- puting Strategy encompasses a hybrid deployment model that includes

BENEFITS TO THE ARMY Today’s data center environment, with more
than 1,000 locations, is
cost- prohibitive to sustain and nearly impossible to secure because of the vast cyber attack
surface and inconsistent,
untimely cybersecurity practices. Tis target-rich Army
environment prevents from adequately protecting
the its
information resources and fully exploit- ing economies of scale. It also prevents the Army from keeping pace with emerg- ing technology and setting conditions to harness the power of “big data” analyt- ics—working with data sets so large or complex that traditional data processing applications are inadequate.
Cloud computing upends this paradigm. When the appropriate cloud service model is used, the Army reaps a slew of benefits. Application owners no longer
acquire specific, dedicated computing resources; rather, they contract for these resources as a service from a CSP, which then hosts applications and data in a common,
shared computing environ-
ment. Overall software licensing costs drop through centralized delivery.
In the aggregate, the Army’s cybersecurity posture improves dramatically. Instead of 1,000 or more open connections the network that must be
to supported
today, DOD intends to have fewer than 85. Additionally, centrally managed and pushed patches for software and operating systems speed the implementation of fixes to “zero day” vulnerabilities (vulnerabili- ties that the developer is not aware of but a hacker may have found, and therefore the developer has zero days to fix them) and lower hands-on labor requirements.
premises DOD (for example, milCloud, which is housed in DOD facilities) and commercial CSPs and off-premises fed- eral (such as NASA or the Department of Homeland Security) and commercial CSPs and cloud computing infrastruc- ture in the tactical environment. Te Army determines the “best cloud” deployment and service for each applica- tion through an engineering evaluation process that considers migration readi- ness, information security requirements, mission requirements and cloud service provider capabilities.
Off-premises cloud pilots: Te Army is leveraging the Defense Information Sys- tems Agency (DISA) cloud pilot program, which uses an off-premises commercial CSP. Te pilot is not only evaluating the security capabilities provided by the CSP, but it also is helping to shape the security requirements for DISA-provided cloud access points (CAPs), which provide boundary security for the Department of Defense Information Network. Te final CAP architecture is now in place and is
