Filling Holes in the SOA Stack with Runtime Governance
ZapThink considers runtime SOA governance a requirement of successful SOA, greatly increasing the chances that the SOA implementation will have business value. Indeed, the lack of adequate runtime SOA governance greatly reduces the chances of success. The ability to create and monitor policies, manage performance, secure the system, and provide self-healing mechanisms means the SOA implementation will provide ongoing value through productivity benefits. However, most SOA stack vendors do not address many of the key requirements of SOA, including solution patterns around runtime SOA goverance. Considering this limitation, it’s important to address these issues with the proper technology, leveraged in the proper way. Thus, the purpose of this paper.

SOA Performance
Many organizations look to Service-Oriented Architecture (SOA) to provide greater business agility in the face of evolving business requirements and complex, heterogeneous information technology (IT) environments. To achieve this agility, architects implement a Services abstraction that loosely couples business Services from the underlying implementations of those Services. Building such an abstraction layer is not without risks, however–inherent in building such an abstraction is the risk of sacrificing performance and scalability to achieve the organization’s required agility. As SOA becomes mainstream, though, enterprises simply cannot afford to trade away performance to achieve agility. As a result, architects must plan for performance up front, as part of their SOA planning process, and leverage a variety of techniques and solutions to achieve performance and scalability as well as business agility as the traffic to their Services continues to increase.[hide -1]Download File[/hide][hide +0]Register to Access this Document[/hide]…

Effective Governance of the Service Lifecycle
Service-Oriented Architecture (SOA) governance, consisting of creating, communicating, and enforcing the policies that apply to the design, deployment, and management of Services, is one of the most critical, yet confusing, part of an effective SOA plan. One of the reasons why SOA governance is so important, as well as challenging, is that SOA teams must govern the entire Service lifecycle, not just as the team models and develops the Services at design time, but also as they deploy and manage them at run time, and reconfigure and recompose them at change time. An important part of the SOA infrastructure for enabling SOA governance is the registry/repository. Today’s registry/repositories are fully featured SOA metadata management solutions that coordinate policy activities and enable policy enforcement across the Service lifecycle. As organizations roll out their SOA initiatives, it is important to consider SOA governance as one of the initial steps, and a…

Design & Validate SOA in a Heterogeneous Environment
The promised business value of Service-Oriented Architecture (SOA) is driving many enterprises to purchase key SOA-related technologies, such as an Enterprise Service Bus (ESB), in advance of the forthcoming architecture. However, the road to SOA is not always clear, and many enterprise architects, developers, and project leaders require guidance to understand the steps to SOA success. Such guidance must include clear, interactive, and adaptive process that ensures that team members understand all requirements, document all details, and plan all testing and implementation tasks. The purpose of this manual is to walk those charged with designing and building their SOA implementation through the issues, steps, and procedures they require to create their first iteration of SOA, and how to build on that experience to drive a more systemic change within their enterprise. We’re going to take you through this journey assuming that you have the technology on hand, whether that…

Governance, Quality, and Management
Service-Oriented Architecture (SOA) is an approach to organizing IT resources to better meet the changing needs of the business. While many organizations are somewhere on their SOA roadmaps, many such organizations face challenges when planning the underlying infrastructure that will support their SOA implementation. One reason for this challenge is that there are three core infrastructure areas that are jointly essential to the success of separate, but overlapping SOA effort: governance, quality, and management. Governance means creating, communicating, and enforcing the policies that apply to the behavior of IT and its users. Quality is a measure of how well working systems meet the needs of the business. Management focuses on how well those systems meet performance, security, and other non-functional requirements for working software. In the context of SOA, however, these three sets of capabilities begin to merge. To provide the business agility benefit that is the core…

Reaching the SOA Tipping Point
The core benefits that Service-Oriented Architecture (SOA) promises–cost reduction, increased business visibility, business empowerment, and greater business agility–are becoming increasingly understood and sought after, but the fact remains that many organizations are still struggling with various challenges in the early stages of their SOA initiatives. Many such challenges are organizational and political, and as a result, many well-meaning SOA initiatives have devolved into stopgap measures and political compromises. Such projects risk failure, delays, and cancellations. To avoid such pitfalls, it’s increasingly important for organizations to take a pragmatic approach to SOA adoption that achieves business goals under the radar, building momentum and business value iteratively. For architects who are fed up with the status quo of IT and can see the big picture of the SOA value proposition for their organizations, taking such a pragmatic approach can be the most effective way to achieve the SOA tipping point, where…

The Seven Levels of Loose Coupling
When ZapThink talks about Service-Oriented Architecture (SOA), we generally try to avoid semantic arguments about what is and what isn’t SOA, but rather try to focus on specific characteristics that identify Service-oriented systems and the benefits they provide organizations that adopt the architectural approach. In particular, we like to focus on three core tenets: loose coupling of Service consumers and providers, composability at a variety of levels of granularity, and event-driven, asynchronous styles of interaction that allow for a wide range of usage scenarios. While these characteristics might seem distinct, they are in fact related to each other. The ability to compose arbitrary Services in environments of long-running transactions requires a certain measure of loose coupling. However, architects seem to grapple with the term “loose coupling”. Some erroneously think that systems are either loosely coupled or tightly coupled as if the determination of coupling is a binary evaluation. The…
