The next-generation of service-oriented architecture (SOA) needs to scale for flexible service consumption, beyond organizational and application boundaries, into communities, ecosystems and business networks. In wider and, ultimately, global settings, new capabilities are needed so that business partners can efficiently and reliably enable, adapt and expose services. Those services can then be discovered, ordered, consumed, metered and paid for, through new applications and opportunities, driven by third-parties in the global "village". This trend is already underway, in different ways, through different early adopter market segments. This paper proposes an architectural strategy for the provisioning and delivery of services in communities, ecosystems and business networks - a Service Delivery Framework (SDF). The SDF is intended to support multiple industries and deployments where a SOA platform is needed for collaborating partners and diverse consumers. Specifically, it is envisaged that the SDF allows providers to publish their services into network directories so that they can be re-purposed, traded and consumed, and leveraging network utilities like B2B gateways and cloud hosting. To support these different facets of service delivery, the SDF extends the conventional service provider, service broker and service consumer of the Web Services Architecture to include service gateway, service hoster, service aggregator and service channel maker.
[Show abstract][Hide abstract] ABSTRACT: Security is a key barrier to the broader adoption of cloud computing. The real and perceived risks of providing, accessing and controlling services in multitenant cloud environments can slow or preclude the migration to services by IT organizations. In a non-virtualized environment, the separation provided by physical infrastructure is assumed to provide a level of protection for applications and data. In the cloud, this traditional physical isolation between applications no longer exists. Cloud infrastructure is multi-tenant, with multiple applications utilizing a shared common physical infrastructure. This provides the benefit of much more efficient resource utilization. However, because the physical barriers between applications have been eliminated, it is important to establish compensating security controls to minimize the potential for malware to spread through the cloud. Newer types of malware threats, such as rootkit attacks, can be increasingly difficult to detect using traditional antivirus products. These threats use various methods of concealment to remain undetected as they infect key system components such as hypervisors and drivers. This increases the likelihood that the malware can operate in the background, spread through a cloud environment, and cause greater damage over time. This paper explores challenges in deploying and managing services in a cloud infrastructure from a security perspective, and as an example, discusses work that Intel is doing with partners and the software vendor ecosystem to enable a security enhanced platform and solutions with security anchored and rooted in hardware and firmware to increase visibility and control in the cloud.

[Show abstract][Hide abstract] ABSTRACT: Traditionally, in a typical SOA environment, a B2B gateway is at the edge of an enterprise, and is responsible for performing business document exchanges with other enterprises. In the existing model often used in mature markets, the enterprise needs to incur the cost of hosting and maintaining the gateway. However, the scenario for emerging markets is different, since they are not totally reliant on exchanging business documents electronically. Specifically, the SMB enterprises in emerging markets may not be interested in hosting and maintaining the usually bulky gateway products. In this paper, we propose a novel approach wherein SMB enterprises would exchange secured business information to a B2B cloud service hosted outside of the enterprise. This service offers key B2B protocol capabilities and features such as packaging, security and partner on-boarding. In a typical document exchange flow, the SMB enterprise would send it's business information to this B2B cloud service which then packages it using the agreed upon B2B protocol and makes it available to the intended recipient enterprise. Using this model for B2B exchanges would work as an incentive to open up SMB enterprises for B2B business and will go a long way in reducing costs for SMB enterprises.
