IBM App Connect Enterprise

IBM App Connect Enterprise (abbreviated as IBM ACE, formerly known as IBM Integration Bus or WebSphere Message Broker) is IBM's integration broker from the WebSphere product family that allows business information to flow between disparate applications across multiple hardware and software platforms. Rules can be applied to the data flowing through the message broker to route and transform the information. The product is an Enterprise Service Bus supplying a communication channel between applications and services in a service-oriented architecture.
IBM ACE provides capabilities to build solutions needed to support diverse integration requirements through a set of connectors to a range of data sources, including packaged applications, files, mobile devices, messaging systems, and databases. A benefit of using IBM ACE is that the tool enables existing applications for Web Services without costly legacy application rewrites. ACE avoids the point-to-point strain on development resources by connecting any application or service over multiple protocols, including SOAP, HTTP and JMS. Modern secure authentication mechanisms, including the ability to perform actions on behalf of masquerading or delegate users, through MQ, HTTP and SOAP nodes are supported such as LDAP, X-AUTH, O-AUTH, and two-way SSL.
A major focus of IBM ACE in its latest release is the capability of the product's runtime to be fully hosted in a cloud. Hosting the runtime in the cloud provides certain advantages and potential cost savings compared to hosting the runtime on premises as it simplifies the maintenance and application of OS-level patches which can sometimes be disruptive to business continuity. Also, cloud hosting of IBM ACE runtime allows easy expansion of capacity by adding more horsepower to the CPU configuration of a cloud environment or by adding additional nodes in an Active-Active configuration. Another advantage of maintaining ACE runtimes in the cloud is the ability to configure access to your ACE functionality separate and apart from your internal network using DataPower or API Connect devices. This allows people or services on the public internet to access your Enterprise Service Bus without passing through your internal network, which can be a more secure configuration than if your ESB was deployed to your internal on premises network.
IBM ACE embeds a Common Language Runtime to invoke any .NET logic as part of an integration. It also includes full support for the Visual Studio development environment, including the integrated debugger and code templates. IBM Integration Bus includes a comprehensive set of patterns and samples that demonstrate bi-directional connectivity with both Microsoft Dynamics CRM and MSMQ. Several improvements have been made to this current release, among them the ability to configure runtime parameters using a property file that is part of the deployed artifacts contained in the BAR ('broker archive') file. Previously, the only way to configure runtime parameters was to run an MQSI command on the command line. This new way of configuration is referred to as a policy document and can be created with the new Policy Editor. Policy documents can be stored in a source code control system and a different policy can exist for different environments (DEV, INT, QA, PROD).
IBM ACE is compatible with several virtualization platforms right out-of-the-box, Docker being a prime example. With ACE, you can download from the global Docker repository a runtime of IBM ACE and run it locally. Because ACE has its administrative console built right into the runtime, once the Docker image is active on your local, you can do all the configuration and administration commands needed to fully activate any message flow or deploy any BAR file. In fact, you can construct message flows that are microservices and package these microservices into a Docker deployable object directly. Because message flows and BAR files can contain Policy files, this node configuration can be automatic and no or little human intervention is needed to complete the application deployment. 
Features.
IBM represents the following features as key differentiators of the IBM ACE product when compared to other industry products that provide the services of an Enterprise Service Bus:
IBM delivers the IIB software either in traditional software install on your local premises, on premise IBM Cloud Private or by an IBM administered cloud environment. The Integration Bus in a cloud environment reduces capital expenditures, increases application and hardware availability, and offloads the skills for managing an Integration Bus environment to IBM cloud engineers. This promotes the ability of end users to focus on developing solutions rather than installing, configuring, and managing the IIB software. The offering is intended to be compatible with the on-premises product. Within the constraints of a cloud environment, users can use the same development tooling for both cloud and on-premises software, and the assets that are generated can be deployed to either.
History.
Originally the product was developed by NEON (New Era of Networks) Inc., a company which was acquired by Sybase in 2001. The product was later re-branded as an IBM product called 'MQSeries Integrator' (or 'MQSI' for short). Versions of MQSI ran up to version 2.0.
The product was added to the WebSphere family and re-branded 'WebSphere MQ Integrator', at version 2.1.
After 2.1 the version numbers became more synchronized with the rest of the WebSphere family and jumped to version 5.0. The name changed to 'WebSphere Business Integration Message Broker' (WBIMB). In this version the development environment was redesigned using Eclipse and support for Web services was integrated into the product.
Since version 6.0 the product has been known as 'WebSphere Message Broker'. WebSphere Message Broker version 7.0 was announced in October 2009, and WebSphere Message Broker version 8.0 announced in October 2011
In April 2013, IBM announced that the WebSphere Message Broker product was undergoing another rebranding name change. IBM Integration Bus version 9 includes new nodes such as the Decision Service node which enables content based routing based on a rules engine and requires IBM WebSphere Operational Decision Management product. The IBM WebSphere Enterprise Service Bus product has been discontinued with the release of IBM Integration Bus and IBM is offering transitional licenses to move to IBM Integration Bus. The WebSphere Message Broker Transfer License for WebSphere Enterprise Service Bus enables customers to exchange some or all of their WebSphere Enterprise Service Bus license entitlements for WebSphere Message Broker license entitlements. Following the license transfer, entitlement to use WebSphere Enterprise Service Bus will be reduced or cease. This reflects the WebSphere Enterprise Service Bus license entitlements being relinquished during the exchange. IBM announced at Impact 2013 that WESB will be end-of-life in five years and no further feature development of the WESB product will occur.
Components.
IBM Integration Bus consists of the following components:
How IBM Integration Bus works.
A SOA developer defines message flows in the IBM Integration Toolkit by including a number of message flow nodes, each of which represents a set of actions that define a processing step. The way in which the message flow nodes are joined together determine 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 it 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 Integration Bus supports a wide variety of data formats, including standards-based formats (such as XML, DFDL, and JSON), industry formats (such as HL7, EDI and SWIFT), and 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 Integration Bus unifies the Business Process Management grid, providing the workhorse behind how to do something, taking directions from other BPM tooling which tells IBM Integration Bus what to do.
IBM Integration Bus includes a set of performance monitoring tools that is 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.
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.
IBM Integration Bus 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 Integration Bus 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. A key feature of IBM Integration Bus is the ability to abstract the business logic away from transport or protocol specifics.
The IBM Integration Bus 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. 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. 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 Integration Bus 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. 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 $14 billion (up $7 billion from 2011). License and maintenance revenue for IBM middleware products reached $7 billion 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 $19.4 billion, 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 WebSphere Message Broker which 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.
With version 8 onwards, a new Global Cache feature enhances overall performance capability and throughput rates. This cache rides on top of IBM WebSphere eXtremeScale and is bundled with IBM Integration Bus. A dedicated message flow node is available to use in message flows, or access to the cache can be achieved through any of the compute nodes, from languages like Java, ESQL, or .Net.
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:
Localization.
IBM Integration Bus on distributed systems has been localized to the following cultures:
Patterns.
A pattern captures a commonly recurring solution to a problem (example: 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:
The patterns cover a range of categories including file processing, application integration, and message based integration.
