  • IT Best Practices - Legacy System Renewal Adoption, ROI, and TCO

    Legacy System Renewal Adoption, ROI, and TCO

    The decision whether to renew or replace legacy applications is an economic one that many IT managers are wrestling with as organizations seek to exploit Internet-enabled business processes and mobile applications. In this study, we assess current adoption and investment rates for legacy system renewal projects based on our annual survey of 200 IT organizations. Next, to determine risks associated with renewal projects we look at the return on investment (ROI) and total cost of ownership (TCO) experiences of organizations that have undertaken such projects. Finally, we examine trends by organization size and conclude with a summation of best practices. (12 pp., 7 figs.) [Research Byte]

  • Technology Trends - SaaS Returns Bolster Cloud Computing’s Promise

    SaaS Returns Bolster Cloud Computing’s Promise

    IT organizations are turning more and more to “the cloud” for computing resources, whether they be applications, data center infrastructure, development platforms, or services. In this study, we present adoption trends, return on investment, and total cost of ownership experiences for software as a service (SaaS), which represents one significant component of the cloud computing paradigm. We also define cloud computing by looking at some of the major vendor offerings and conclude with key points IT managers should consider when evaluating cloud computing options.

  • Technology Trends - SOA Adoption Rising: ROI Positive But Beware of Costs

    SOA Adoption Rising: ROI Positive But Beware of Costs

    For years, organizations have been seeking ways to increase the productivity of application development personnel while improving the quality of their information systems. This study documents an increase in adoption of service-oriented architecture (SOA), as an answer to this dilemma. It breaks down adoption by stages of implementation and organization size, and it takes inventory of ROI and TCO experiences with SOA initiatives. We also look at adoption rates for the competing Java and Microsoft .NET frameworks for developing SOA services. In conclusion, we examine the benefits and challenges of SOA in practice and give advice on how to ensure SOA stays a solid investment in the long run. (11 pp., 7 figs.)[Executive Summary]

    Legacy System Renewal: Adoption Trends and Economic Experiences

    The decision whether to renew or replace legacy applications is an economic one that many IT managers are wrestling with today. In this study, we first assess current adoption and investment rates for legacy system renewal projects, based on our annual survey of about 200 IT organizations. Next, to determine risks associated with legacy system modernization we look at the return on investment (ROI) and total cost of ownership (TCO) experiences of organizations that have undertaken such projects. Finally, we examine trends by organization size and conclude with a summation of our findings and key recommendations. (4 pp., 9 figs.)[Executive Summary]

  • Technology Trends - Service-Oriented Architecture: Adoption Trends in 2007

    Service-Oriented Architecture: Adoption Trends in 2007

    Although the promises of service-oriented architecture (SOA) are great, nearly half of all organizations have taken no steps toward adopting the technology, not even preliminary research. Based on a 2006 survey of nearly 200 senior IT executives, this article analyzes trends in SOA adoption by organization size and industry sector. It discusses the categories of SOA adoption and the reasons why SOA is being deployed more rapidly in certain types of firms. It also provides recommendations for maximizing the benefits of this technology for end-user organizations and IT service providers in light of these findings. (5 pp., 5 figs.)[Executive Summary]

    A Phased Approach to SOA

    Because rolling out a service-oriented architecture can be a massive undertaking, most companies will be best served by taking a gradualistic approach. This Research Byte provides a brief summary of our full report on this subject.

  • Technology Trends - Implementing a Service-Oriented Architecture

    Implementing a Service-Oriented Architecture

    In its fullest context, a service oriented architecture (SOA) requires rethinking and redefining business processes, and the software applications that support them, in terms of "services." Therefore, it is impossible for most organizations to implement SOA quickly. This report provides a basic overview of SOA, its advantages and disadvantages, and practical recommendations for implementing SOA in an incremental fashion. [Executive Summary]

  • Technology Trends - Web Services and Service-Oriented Architecture (SOA)

    Web Services and Service-Oriented Architecture (SOA)

    Although just beginning to take shape, the vision for Web services is to provide interoperability between disparate systems so that isolated applications and data can be integrated into a single Information Systems framework. In a world of burgeoning e-commerce, Web applications and interoperability can make or break a business. What are the business drivers for deploying Web services, and how does it impact your existing IT infrastructure? What are the issues, pitfalls, and benefits of an SOA and Web services? Who are the early adopters? How can you prepare?
