唯有让数据大集成才能让SOA稳着陆

这种解决办法不同于传统的数据集成。ZapThink的Schmelzer回忆说：“我们过去一直通过在关键堵点上实施控制来解决数据集成问题。而SOA消除了这些堵点。这意味着每个数据访问点都必须能转换和管理数据。”

Distributed Management Task Force focuses on cloud standards

“Standards for cloud computing are an essential part of the cloud computing story, but are not without challenges,” said ZapThink principal analyst Jason Bloomberg. “Cloud computing takes virtualization to multiple levels, including data exchange, but also ranging across operating system functionality, application functionality, as well as service interfaces.”

Secondly, the working group will create cloud APIs and protocols for resource management so that cloud computing resources may be managed like the rest of an organization’s IT infrastructure, Bloomberg said. Quality-of-service policy management will be included in this effort.

Better Goverance for IT Results

Few topics in today’s organizations present such a diverse set of both business and technology challenges as governance. Governance consists ofestablishing chains of responsibility, policies that guide the organization, control mechanisms to ensure compliance with those policies, and communication and measurement amongst all parties. However, what constitutes a policy and what activities and tools the organization requires for governance are questions that have a broad diversity of answers.

Nowhere are the differences among various definitions of governance more pronounced than in the contrast between lines of business and information technology (IT). From the business perspective, top executives as well as government regulators set policies for the organization, which explain in often broad terms how various individuals within the company must act in certain circumstances. From the IT perspective, however, governance covers a range of policies that span the gamut from purchasing and hiring policies all the way to firewall and coding policies and enforcing service-level agreements.

Service-Oriented Architecture (SOA) is a well-adopted approach to organizing IT resources to better meet the changing needs of the business. Governance is essential to ensuring that organizations realize the business benefits of SOA consistently through their IT implementations. Furthermore, as such firms adopt SOA, they become better able to provide more flexible governance overall. The big win for SOA governance, therefore, extends well beyond the SOA initiative and applies the lessons of SOA governance into all parts of the organization.

This paper explores the relationship among SOA, IT and corporate governance, defines the key lessons of SOA governance, and summarizes how these best practices expand well beyond SOA to deliver better governance overall.

SOA and TOGAF: A Good Fit?

By guest contributors Clive Hatton and Paul van der Merwe, Real IRM.

Service-Oriented Architecture (SOA) is a style of architecture and The Open Group Architecture Framework (TOGAF) is an architecture framework. The combination sounds promising, but do they play well together? The Open Group certainly believes they do …
