PingTrust builds on two open security standards that set the stage for true interoperability and a solution that scales. OASIS Web Services Security 1.0 (formerly WS-Security) allows for the embedding of security tokens in SOAP messages, while WS-Trust establishes a mechanism for obtaining and validating tokens from a Security Token Service (STS). PingTrust is such an STS. It supports both .NET and Java applications, Web-based and rich clients. PingTrust can operate on the Web Services Client-side, Provider-side or both sides of a Web Service transaction.
"With PingTrust, the concept of user session no longer ends at the application a user originally logs into, either directly or via federation," commented Patrick Harding, chief technical officer of Ping Identity. "Instead, user session and identity now follow SOAP messages wherever they may go throughout the SOA."
"By supporting WS-Trust, Ping Identity is providing a Security Token Service that can participate in the Identity Metasystem. This enables identity information to be exchanged using industry standard Web services, regardless of the underlying platforms," said Michael Stephenson, director of identity and access at Microsoft. "We look forward to Ping's products interoperating with Microsoft technologies, including .NET, Active Directory and the upcoming 'InfoCard' technology."
Using PingTrust, a Web Services client can exchange the security token being used in the local security domain, such as a Kerberos ticket, for a SAML token that represents the original user's identity in other federated security domains, including those at other companies. After being bound into a SOAP message and delivered to a Web Services Provider, the Provider will know who originated the request and will be able to use that information in determining how to process the request.
"Ping has leveraged the insights of Fidelity Investments as a design partner to create its market-leading Security Token Server for Web Services security and federated Web Services," said Dave Power, partner at Fidelity Investments.
PingTrust is a lightweight, standalone, modular product that:
Researchers from the Suddhananda Engineering and Research Centre in Bhubaneswar, India developed a job scheduling system, which they call Service Level Agreement (SLA) scheduling, that is meant to achieve acceptable methods of resource provisioning similar to that of potential in-house systems. They combined that with an on-demand resource provisioner to ensure utilization optimization of virtual machines.
Experimental scientific HPC applications are continually being moved to the cloud, as covered here in several capacities over the last couple of weeks. Included in that rundown, Co-founder and CEO of CloudSigma Robert Jenkins penned an article for HPC in the Cloud where he discussed the emergence of cloud technologies to supplement research capabilities of big scientific initiatives like CERN and ESA (the European Space Agency)...
When considering moving excess or experimental HPC applications to a cloud environment, there will always be obstacles. Were that not the case, the cost effectiveness of cloud-based HPC would rule the high performance landscape. Jonathan Stewart Ward and Adam Barker of the University of St. Andrews produced an intriguing report on the state of cloud computing, paying a significant amount of attention to the problems facing cloud computing.

The San Diego Supercomputer Center launched a public cloud system for universities in the area designed specifically to run on commodity hardware with high performance solid-state drives. The center, which currently holds 5.5 PB of raw storage, is open to educational and research users in the University of California.
05/10/2013 | Cleversafe, Cray, DDN, NetApp, & Panasas | From Wall Street to Hollywood, drug discovery to homeland security, companies and organizations of all sizes and stripes are coming face to face with the challenges – and opportunities – afforded by Big Data. Before anyone can utilize these extraordinary data repositories, however, they must first harness and manage their data stores, and do so utilizing technologies that underscore affordability, security, and scalability.
04/02/2012 | AMD | Developers today are just beginning to explore the potential of heterogeneous computing, but the potential for this new paradigm is huge. This brief article reviews how the technology might impact a range of application development areas, including client experiences and cloud-based data management. As platforms like OpenCL continue to evolve, the benefits of heterogeneous computing will become even more accessible.
