More and more organizations are looking to SOA as the basis of their future computer architecture. Recognizing that legacy application design and implementation approaches have led to applications that are costly to operate, hard to change, organizations are hoping that SOA provides a key component of the answer to these problems. 

Service-oriented architecture (SOA) enables different programs, applications, and tools to interact via self-contained services that do not depend on the context or state of the other service. This white paper provides insight into the top-four worst practices for SOA integration, and how to avoid and/or overcome these worst practices. 

This week’s Computer Weekly kicks off our Buyer's Guide to data security by looking at the changing role of the IT security chief. We also examine why flexible working is proving so slow to roll out and we talk to the UK's air traffic control operator about its ambitious desktop virtualisation project. 

This paper examines the impact of de-duplication in a disk-to-disk-to-tape (D2D2T) backup and recovery environment. 

The Department of Defense's manual, DoD 8570.01-M Information Assurance Workforce Improvement Program, supports DoD Directive 8570.1, which requires all individuals possessing privileged access to a DoD Information System (IS) to be trained and certified in the secure operation of computer systems used throughout the DoD's Global Information Grid. 

Sun Fire™ x64 servers and Sun Blade™ modular systems powered by AMD Opteron™ and Intel® Xeon® processors let businesses run the Solaris™ Operating System (OS), Linux or Windows today, and change direction tomorrow. 

Virtualized iSCSI SANs are increasingly being chosen for virtual data center deployments because they help simplify storage management and help overcome performance, scalability and cost barriers of traditional SAN architectures. 

The DXi7500 is the disk backup and remote replication system for data centers where a premium is placed on scalability, performance, high availability, and flexibility. 

In earlier times, if an enterprise presumed it had control over its network, and if it had few external connections or communication, it was feasible that the connections between operational computers probably were not an unacceptable risk. 

This white paper provides high level definitions, opportunity identification, and future potentials for: Service Oriented Architecture (SOA), Software as a Service (SaaS), Enterprise Resource Planning (ERP) Anytime, Anywhere Availability, Mobile Devices, Web 2.0, and Report Cards or Balanced Scorecards as a Business Intelligence (BI) capability. 

Explore the fundamentals of SCSI and internet SCSI (iSCSI) in this expert resource. Learn about the architecture, protocol, operations, and numerous interfaces and commands the SCSI model uses. In addition, gain understanding of the use of Fibre Channel and iSCSI to build out SCSI over a network. 

This white paper discusses the issues associated with decision services in an SOA strategy, highlighting how business rule management systems can be used to overcome these challenges.
