Features and benefits

IBM® WebSphere® MQ enables you to reliably and consistently integrate your applications, allowing you to fully leverage your existing software and hardware assets. As the market leader for message-oriented middleware, it offers scalable, enterprise-class connectivity that grows with your integration challenges and needs. WebSphere MQ enables you to begin deploying your enterprise service bus (ESB) today and gain the benefits of an integrated service oriented architecture (SOA).

WebSphere MQ provides reliable, resilient application integration by passing messages between applications and Web services. It reduces the risk of information loss and the need to reconcile communicating IT systems by using queuing and transactional facilities that help preserve the integrity of messages throughout the network. WebSphere MQ eliminates the need to write complex communications code and offers a choice of simple APIs (Message Queue Interface and Java Message Service™) that are consistent through a range of more than 80 supported operating environments, provided both by IBM and Business Partners.

Overview

Assured delivery

WebSphere MQ can reduce the risk of data being lost when applications, Web services (US) or networks fail. It also helps ensure that data is not duplicated and completes as a single unit of work or transaction. This assured delivery means that WebSphere MQ forms the backbone of many critical communication systems and is entrusted with delivering business-critical and high-value data. WebSphere MQ can deliver information either synchronously or asynchronously depending on the needs of the applications and Web services (US). It can also be configured to provide a less-robust quality of service for increased performance on less-critical data.

Powerful development facilities

WebSphere MQ simplifies integration tasks by providing a functionally rich -- yet easy to use -- application development interface that removes the data movement and storage logic from the application, helping users to focus on the business logic.

WebSphere MQ provides a consistent application programming interface, MQI, throughout all its supported platforms, which helps make integrated programs portable. In addition to this de facto standard interface, WebSphere MQ also fully implements the industry standard Java Message Service (JMS) interface, including support for publish and subscribe messaging.

The WebSphere MQ Explorer tool, included in the product, enables the entire MQ network to be administered and configured remotely. Based on the open source Eclipse™ framework, this administration and configuration tool is extensible.

End-to-end security

WebSphere MQ supports Secure Sockets Layer (SSL) for authentication, message integrity checking and encryption for data sent over the Internet. SSL has become the de facto standard for Internet security and is widely available on different operating systems.

WebSphere MQ Extended Security Edition (US) enhances this security support with end-to-end, application-level data protection features. Available as an upgrade to WebSphere MQ, it enables enterprise-wide, remote management of security polices and can be deployed to existing production environments without changes to existing WebSphere MQ applications.

Web services

WebSphere MQ makes an ideal transport for adding reliability and traceability to SOAP interactions between Web services (US), especially as part of an SOA. Existing and batch applications that are Web services-enabled can also benefit from using WebSphere MQ in its asynchronous mode as a buffering mechanism, regulating the flow of requests made to these systems.

Reliable file transfer

WebSphere MQ reduces the time and skills required to be productive with a new File Transfer application (US) that provides a simple GUI tool to move files over the MQ network with reliability. In addition, simple scripting commands for file transfer enable batches of files to be transferred, triggered by the operating system or by applications.

Clustering

WebSphere MQ supports clustering for dynamically distributing messaging workload throughout available MQ resources.

Time-independent processing

WebSphere MQ helps users send business information to other parts of their business or to Business Partners or customers without waiting for it to arrive. WebSphere MQ users feel safe knowing that as soon as recipients are able to receive it, the information will be delivered. This is particularly useful when the sender and recipient work in different time zones or in different countries.

Time-independent (asynchronous) messaging decouples applications. When applications are running and the network is up, WebSphere MQ in asynchronous mode delivers messages just as quickly as in synchronous mode. Asynchronous messaging enables the messaging layer to cope better with situations where parts of the architecture are unavailable. If this happens, the messages are kept safe and data is eventually processed when it can be.

Integrate virtually anything

Most enterprises today are large, distributed organisations that have accumulated, written or acquired a range of diverse IT systems, often independently over time.

In today's fast-paced business environment, organisations need to invest in using the power of integration to increase their responsiveness and flexibility, instead of wrestling with underlying network complexities to connect applications. Maintaining home-grown approaches for connecting applications wastefully diverts valuable skills and time away from higher-level integration concerns. Offloading these time-consuming tasks to WebSphere MQ frees systems integrators and application developers to apply their skills to higher-level integration challenges that bring further benefits to IT departments and to the business.

Support for growth

WebSphere MQ does more than just enable customers to manage the technology they have today more effectively. It gives them a clear path to the future-a flexible infrastructure in which they can develop and deploy new applications faster and more cost effectively, without writing complex communications code.

Both WebSphere MQ and WebSphere Application Server provide messaging resources that can form the foundation for a company's ESB, which can grow incrementally with their business needs.
