When you want application modernization, it is important that, in the communication phase, that all companies have heterogeneous platforms. You need to communicate, and you need the transactions and all information online.
By implementing messaging technologies, businesses can use a consistent approach to connectivity, and decouple the business application from the complexity of handling failures, error recovery, transaction integrity, security, and scalability.
IBM WebSphere MQ
You can use WebSphere MQ to enable applications to communicate at different times and in many diverse computing environments, as shown
WebSphere MQ is messaging for applications. It sends messages across networks of diverse components. Your application connects to WebSphere MQ to send or receive a message. WebSphere MQ handles the different processors, operating systems, subsystems, and communication protocols it encounters in transferring the message. If a connection or a processor is temporarily unavailable, WebSphere MQ queues the message and forwards it when the connection is back online.
An application has a choice of which programming interfaces and programming languages it uses to connect to WebSphere MQ, as shown
WebSphere MQ is messaging and queuing middleware, with point-to-point, publish and subscribe, and file transfer modes of operation. Applications can publish messages to many subscribers over multicast.
Programs communicate by sending data to each other in messages instead of calling each other directly
Messages are placed on queues so that programs can run independently of each other, at different speeds and times, in different locations, and without having a direct connection between them.
Applications send messages to a queue, or to a list of queues. The sender must know the name of the destination, but not where it is.
Applications publish a message on a topic, such as the result of a game that is played by a team. WebSphere MQ sends copies of the message to applications that subscribe to the results topic. They receive the message with the results of games that are played by the team. The publisher does not know the names of subscribers, or where they are.
Multicast is an efficient form of publish/subscribe messaging that scales to many subscribers. It transfers the effort of sending a copy of a publication to each subscriber from WebSphere MQ to the network. When a path for the publication is established between the publisher and subscriber, WebSphere MQ is not involved in forwarding the publication.
Files are transferred in messages. WebSphere MQ File Transfer Edition manages the transfer of files and the administration to set up automated transfers and log the results. You can integrate the file transfer with other file transfer systems, with WebSphere MQ messaging,
and the web.
WebSphere MQ Telemetry is messaging for devices. WebSphere MQ connects device and application messaging together. It connects the internet, applications, services, and decision makers with networks of instrumented devices. WebSphere MQ Telemetry has an efficient messaging protocol that connects many devices over a network. The messaging protocol is published so that it can be incorporated into devices. You can also develop device programs with one of the published programming interfaces for the protocol.
