SOA Security and Building Secured Services

Introduction

SOA is accepted as an architectural style for organizations. It enables them to have maximal speed and minimal circulation of information flow. Yet, wherever information technology has been developed there are a number of problems and obstacles to achieve this end. It must be borne in mind that using SOA does not warrant success per se. What warrants success is that IT architects must be familiar with the advantages and disadvantages of this technology and be aware of how to use it having in mind the investors of the organization (Koch, 2005). SOA is a new technology which delivers software functions in the form of service. The services acquired can be called on by other applications and be used for constructive new services (chatterjee et al, 2004). SOA is an advancing technology that can introduce dramatic changes in constructive distributed applications. The services consist of discrete elements with predefined and certain interfaces that converse with each other through XML messages. Using SOA, one can come up with solutions which are not limited to the scopes of organizations and companies.

Service-oriented architecture can be investigated from different perspectives: every person or beneficiary has a conception of SOA depending on his position. As follows, the perspectives of IT managers, business managers, designers and implementers of system will be discussed (Bell, 2008):

IT managers: A style of architecture that includes patterns and rules which culminate in the development of characteristics like modularity, packaging, loose coupling, reuse and Composability. It structurally consists of a service-provider and a service-requester.

Business managers: a set of services that organizations wish to provide for their clients or partners.

Designers and implementers of information systems: a style of programming which uses unanimously agreed and technology-independent standards and supports the intractability between software elements regardless of their platform and implementation technology.

Discussion

Service Oriented Architecture

Organizations demand proposals permit giving them the desired levels of agility and flexibility to changes in the business requirements, market dynamism and the demands of customers. The adoption of SOA in organizations raises achieving a number of business benefits, as IT alignment with strategic objectives of the organization, improved agility business and increasing the reuse of services with consequent cost savings, and maintenance time. The implementation of SOA in organizations set a set of challenges, mainly the needs business strategy and processes relating to the forecast of evolution that organizations may have compared to the continuous changes in the market, processes business, products and other issues.

Service-oriented architecture (SOA) and Web service technologies are opening a new era in computing with the promise of a complete application architecture that can deliver its functions across World Wide Web by using the emerging standards and a distributed system model. It is the latest software trend built on the advances in software engineering following the way from monolithic applications into SOA, through structured, object-oriented and component-based software development. The first generation of SOA has already been taken place with the advent of basic ...
