Besides setting out the complete microservices architecture , messaging can help out in many scenarios.
1. If you want the legacy applications to talk to each other without the data loss , messaging with queues is ideal. There are libraries from many programming languages for your message broker that lets you do that.
2. When data is coming from many places and need to power a dashboard Apps than messaging queue can easily be accumulated to give you real time insight on your dashboard scheme.
3. If you have big monolithic app and want to simplify it without rewriting it all at once first isolated one feature or layer to be handled by a service. Handle the communication between the monolith and new service with the messaging. Once done successfully take the next layer till the app is maintainable again.
