Solving the Dependency Problem in Software Builds

This technical whitepaper provides time-saving tips for automating and optimizing dependencies between files in a software build. Three main types of dependencies are discussed: those that exist between source and object files (that are used to regenerate objects when source changes), those that exist between objects (for example, used to drive a linker), and dependencies at the module or project level. For source/object dependencies in particular, instead of generating dependencies manually, there are simple techniques for generating dependencies automatically, saving time and reducing errors and rework. This paper provides specific guidance, complete with examples, for automating dependency generation, and describes some of the challenges left unsolved by traditional freeware/open source dependency management techniques.

Overcoming Mobile Fragmentation: Building Applications for Multiple Operating Systems

There is a mobile war brewing among industry heavyweights pitting Android against Windows, Symbian against iPhone, and many other OSs in between. While on the surface increased competition may benefit consumers, for developers it's a growing nightmare to build applications that run on these different operating systems and try to maintain some degree of compatibility. A single platform that spans all 'Screens of Life' would truly revolutionize the way mobile applications are created.

This paper discusses some of the challenges and trade-offs developers must make and highlights a solution to overcome them.

Intel® SOA Expressway Service Mediation & Governance Performance Comparison to IBM® DataPower XI50

Compliments of Intel SOA Products Division

SOA Expressway is a soft-appliance deployed to address common XML and SOA problem areas such as acceleration, security, service mediation and service governance. SOA Expressway is available for any organization deploying services (SOA), hosted services (SaaS) or Web 2.0 (RIA). It provides superior performance for service mediation and governance use cases outpacing IBM® DataPower XI50 in a direct "apples-to-apples" comparison by 1.5X to 8X at half the cost. This paper presents benchmark test scenarios, cost analysis, and SOAE's multi-core optimized software architectural elements

Hardware appliances such as the IBM® DataPower XI50 are typically deployed in datacenters to solve integration problems around SOA security, governance and mediation. While these types of highly specialized hardware appliances may solve a few specific problems, they are slow to evolve, difficult to repurpose, and incur higher maintenance and operational costs as compared to general purpose server software solutions. Furthermore, hardware appliances are at odds with major cost-saving datacenter trends such as multi-core and virtualization. A multi-core optimized software appliance or service router (SR) is superior offering.

C++ Web Service Development with Eclipse: A How-to Tutorial

Modernizing your existing C++ applications for Web services and SOA has been a challenge — but it doesn't have to be. In this paper, you'll learn how to develop and host high performance C++ and Java services using Eclipse-based code generation and task automation tools in order to transform new and existing C++ applications for use in a Service Oriented Architecture.

Rapid Development of C++ Service Based Applications — What you'll learn:

• Use cases for using C++ in services
• Traditional challenges with integrating C++ with Web services
• Point and click creation of C++ Web Services that use XML, SOAP, and WSDL
• A step-by step example

See how Hydra, a complete integrated development environment (IDE) and framework for C++ and Java applications, can help your organization take the first and most fundamental steps in moving your C++ applications into a SOA.
