Enterprises are increasingly feeling the need for shorter lead time for decision making, the need to extract and present KPI (Key Performance Indicators) to management, and the need for enhanced response capability. These business needs are not in sync with the technological challenges such as the presence of heterogeneous technologies and disparate enterprise systems (e.g., ERP, SCM, CRM, etc.). This situation gets complicated with the increasing number of mergers and acquisitions resulting in the various business units within an enterprise having their own data warehouses. Adding to this is the increasing number of users inside and outside the enterprise who need real-time access to information. In such a scenario, an EDD (Enterprise Digital Dashboard) would improve the lead time and quality of decision making by extracting and generating KPIs from enterprise sof... (more)

SOA Goes Beyond Object-Oriented Programming

The concept of SOA (Service Oriented Architecture) can be illustrated by leveraging commonly understood concepts of object-oriented programming. Services comply with many of the standard principles that form the bedrock of object-oriented programming. However, SOA provides benefits at a much higher level of the IT value chain as discussed below. In the object-oriented world, a class is the core concept that represents an abstraction of a real-world entity or concept with an object being a physical implementation of that class. Let us revisit some of the benefits that may be avai... (more)

Towards Legacy Enablement Using SOA and Web Services

Legacy systems are a core asset at many organizations. These legacy systems have been around for decades and have a very critical impact on day to day business processes. However, owing to a variety of reasons, these legacy systems have high TCO and represent a bottleneck towards the emergence of an agile IT portfolio. In this article we'll focus on a variety of options that may be available for the seamless integration of legacy systems with an enterprise IT portfolio. We converge on legacy enablement using Web services as a viable option towards achieving an integrated, agile a... (more)

The Business Value of SOA-Based Agile IT Architectures

Agile IT systems are systems that are malleable enough to address business uncertainties. Such systems can effectively respond to internal and external stimuli in a very short period of time. Flexible IT systems imply that the IT architecture underlying them is itself flexible and lends itself to incorporating changes in a dynamic fashion. Architectural approaches such as Service Oriented Architecture (SOA) are transforming the way IT systems are designed by bringing in a high degree of reuse and loose coupling of applications. IT architectures include the technology, strategies... (more)

Building Blocks of SOA Governance

SOA initiatives have gathered momentum in the past year with more enterprises either implementing SOA or considering implementing in the near future. The implementations we studied reveal that one of the critical challenges in SOA is designing an effective governance mechanism. A good understanding of governance concepts is essential to implementing and operating a successful SOA. Reliable governance for SOA leads to a manifold increase in an enterprise's ability to achieve the goal of business agility through SOA. Defining IT Governance The IT Governance Institute defines IT gove... (more)
