A SOA developer or integration developer defines message flows in the
IBM ACE Toolkit by including several message flow nodes, each of which represents a set of actions that define a processing step. How the message flow nodes are joined determines which processing steps are carried out, in which order, and under which conditions. A message flow includes an input node that provides the source of the messages that are processed, which can be processed in one or more ways, and optionally deliver through one or more output nodes. The message is received as a
bit stream, without representational structure or format, and is converted by a parser into a tree structure that is used internally in the message flow. Before the message is delivered to a final destination, it is converted back into a bit stream. IBM App Connect supports a wide variety of data formats, including standards-based formats (such as
XML,
DFDL, and
JSON) CSV and many more as well as industry formats (such as
HL7,
EDI and
SWIFT), ISOxxxx and others as well as custom formats. A comprehensive range of operations can be performed on data, including routing, filtering, enrichment, multicast for publish-subscribe, sequencing, and aggregation. These flexible integration capabilities are able to support the customer's choice of solution architecture, including service-oriented, event-oriented, data-driven, and file-based (batch or real-time). IBM App Connect unifies the Business Process Management grid, providing the workhorse behind how to do something, taking directions from other BPM tooling which tells IBM App Connect what to do. IBM App Connect includes a set of performance monitoring tools that visually portray current server throughput rates, showing various metrics such as elapsed and
CPU time in ways that immediately draw attention to performance bottlenecks and spikes in demand. You can drill down into granular details, such as rates for individual connectors, and the tools enable you to correlate performance information with configuration changes so that you can quickly determine the performance impact of specific configuration changes, resource metrics can also be emitted to show what resources are being used by an integration service. In version 7 and earlier, the primary way general text and binary messages were modeled and parsed was through a container called a message set and associated 'MRM' parser. From version 8 onwards such messages are modeled and parsed using a new open technology called
DFDL from the Open Grid Forum. This is IBM's strategic technology for modeling and parsing general text and binary data. The MRM parser and message sets remain a fully supported part of the product; in order to use message sets, a developer must enable them as they are disabled by default to encourage the adoption of the DFDL technology for its ease of use and superior performance characteristics. IBM App Connect supports policy-driven traffic shaping that enables greater visibility for system administrators and operational control over workload. Traffic shaping enables system administrators to meet the demands when the quantity of new endpoints (such as mobile and cloud applications) exponentially increases by adjusting available system resources to meet that new demand, delay or redirect the traffic to cope with load spikes. The traffic monitoring enables notifications to system administrators and other business stakeholders which increases business awareness and enables trend discovery.
Overview IBM App Connect reduces cost and complexity of IT systems by unifying the method a company uses to implement interfaces between disparate systems. The integration node runtime forms the
Enterprise Service Bus of a
service-oriented architecture by efficiently increasing the flexibility of connecting unlike systems into a unified, homogeneous architecture, independent integration servers can be deployed to containers offering a Micro-Services method of integration, allowing App Connect integration services to be managed by container orchestrators such as
OpenShift,
Kubernetes and others. A key feature of IBM App Connect is the ability to abstract the business logic away from transport or protocol specifics. IBM App Connect also provides deployment flexibility by not only supporting the ESB pattern but also container native deployments by separating Integration Servers from the ESB pattern which are a lightweight process hosting the integration flows, these Integration Servers and flows can be deployed across containers managed by orchestration services such as
Red Hat OpenShift, Kubernetes,
Dock Swarm and others, furthermore these Integration servers are optimised for container deployments by only loading resources that are needed to run an integration, offering fast start up times with reduced resource utilisation. The IBM ACE Toolkit enables developers to graphically design mediations, known as message flows, and related artifacts. Once developed, these resources can be packaged into a broker archive (BAR) file and deployed to an integration node runtime environment or a container. At this point, the integration node is able to continually process messages according to the logic described by the message flow. A wide variety of data formats are supported, and may be modeled using standard
XML Schema and
DFDL schema, JSON and others. After modeling, a developer can create transformations between various formats using nodes supplied in the Toolkit, either graphically using a Mapping node, or programmatically using a Compute node using Java, ESQL, or .Net. IBM App Connect message flows can be used in a
service-oriented architecture, and if properly designed by Middleware Analysts, integrated into
event-driven SOA schemas, sometimes referred to as
SOA 2.0 and/or deployed as micro-services in container native deployments. Businesses rely on the processing of events, which might be part of a business process, such as issuing a trade order, purchasing an insurance policy, reading data using a sensor, or monitoring information gathered about IT infrastructure performance. lex-event-processing capabilities that enable analysis of events to perform validation, enrichment, transformation and intelligent routing of messages based on a set of business rules. A developer creates message flows in a cyclical workflow, probably more agile than most other software development. Developers will create a message flow, generate a BAR file, deploy the message flow contained in the BAR file, test the message flow and repeat as necessary to achieve reliable functionality.
Market position Based on earnings reported for IBM's 1Q13, annualized revenue for IBM's middleware software unit increased to US$14 billion (up $7bn from 2011). License and maintenance revenue for IBM
middleware products reached $7bn in 2011. In 2012, IBM expected an increase in both market share and total market increase of ten percent. The worldwide application infrastructure and middleware software market grew 9.9 percent in 2011 to $19.4bn, according to
Gartner. Gartner reported that IBM continues to be number one in other growing and key areas including the Enterprise Service Bus Suites, Message Oriented Middleware Market, the Transaction Processing Monitor market and Integration Appliances.
Expected performance IBM publishes performance reports for IBM Integration Bus V10 and App Connect Enterprise V11, App Connect V12 reports can be requested for both ESB and Container measurements. The reports provide sample throughput figures. Performance varies depending on message sizes, message volumes, processing complexity (such as complexity of message transformations), system capacities (CPU, memory, network, etc.), software version and patch levels, configuration settings, and other factors. Some published tests demonstrate message rates in excess of 10,000 per second in particular configurations.
Message flow nodes available A developer can choose from many pre-designed message flow 'nodes', which are used to build up a message flow. Nodes have different purposes. Some nodes map data from one format to another (for instance, Cobol Copybook to canonical XML). Other nodes evaluate content of data and route the flow differently based on certain criteria
Message flow node types There are many types of node that can be used in developing message flows; the following node transformation technology options are available: • Graphical Mapping content •

Patterns A
pattern captures a commonly recurring solution to a problem (e.g. Request-Reply pattern). The specification of a pattern describes the problem being addressed, why the problem is important, and any constraints on the solution.
Patterns typically emerge from common usage and the application of a particular product or technology. A pattern can be used to generate customized solutions to a recurring problem in an efficient way. We can do this pattern recognition or development through a process called
service-oriented modeling. Version 7 introduced
patterns that: • Provide guidance in implementing solutions • Increase development efficiency because resources are generated from a set of predefined templates • Improve quality through asset reuse and common implementation of functions such as error handling and logging The
patterns cover a range of categories including file processing, application integration, and message based integration.
