Private Virtual Infrastructure is a security architecture for cloud computing which uses a new trust model to share the responsibility of security in cloud computing between the service provider and client, decreasing the risk exposure to both. Private Virtual Infrastructure is under control of the information owner while the cloud fabric is under control of the service provider. The Private Virtual Infrastructure architecture comprises a cluster of trusted computing fabric platforms that host virtual servers running an application server with a Locator Bot security service. The cloud Locator Bot pre-measures the cloud platform for security properties to determine the trustworthiness of the platform. The Locator Bot uses Trusted Execution Technology and virtual Trusted Platform Modules to pre-measure the target environment and securely provision the Private Virtual Infrastructure in the cloud thus protecting information by preventing data from being placed in malicious or untrusted environments. Private Virtual Infrastructure-- including Locator Bot--provides organizations tools to maintain control of their information in the cloud and realize benefits of cloud computing, with assurance that their information is protected. This paper presents a cloud trust model, Private Virtual Infrastructure architecture, and a Locator Bot protocol in enough detail to support further analysis or implementation.

Two projects at NASA Marshall Space Flight Center have collaborated to develop a high resolution weather forecast model for Mesoamerica: The NASA Short-term Prediction Research and Transition (SPoRT) Center, which integrates unique NASA satellite and weather forecast modeling capabilities into the operational weather forecasting community. NASA's SERVIR Program, which integrates satellite observations, ground-based data, and forecast models to improve disaster response in Central America, the Caribbean, Africa, and the Himalayas.

The Marine Corps is implementing a private cloud computing environment (PCCE) with the intent of alignment of its enterprise processes to programs of record and ensuring technical solutions are mission oriented and geographically informed. The Marine Corps PCCE services will provide access from anywhere across the Marine Corps information environment at any time, via the Marine Corps Enterprise Network (MCEN) to a shared pool of configurable computing resources (e.g., networks, servers, storage, applications, and services) that can rapidly be provisioned and released with reduced management effort. The Marine Corps PCCE will provide access to applications and data to all Marines, in garrison and forward deployed environments through Marine Corp s programs and initiatives. This cloud environment will host applications and provide federated enterprise services (see Appendix II) in a fashion that enhances the operational capabilities and effectiveness of a knowledge based force. The federated shared environment will improve operational effectiveness by providing forward deployed forces the ability to reach cloud services when reachback is available. This will also allow them to operate autonomously when reachback is unavailable. Federation achieves effectiveness. Efficiencies will be achieved through informed and judicious implementation, resulting in a reduced total cost of IT ownership. Enterprise cloud services will be distributed by the MCEN (transport) and provided via MCEITS and other PORs, which are elements of the Marine Corps Information Technology Environment. The USMC Cloud Strategy is rooted in the National Institute of Standards and Technology (NIST) Definition of Cloud Computing and the Federal Cloud Computing Strategy. The foundational enabler for the USMC Cloud Strategy is the Marine Corps Enterprise Information Technology Services (MCEITS), which establishes the Marine Corps guidance for synchronizing current Marine Corps IT programs.
