With the advent of the microservices revolution, the Enterprise Service Bus has also seen a change, where it has now been replaced by some similar solutions, but with the advantages of far better scalability and the removal of single point of failure.
The ESB in application integration used to play the role of a central bus, which acted as an intermediary between the applications that wanted to communicate with each other. The ESB facilitated this communication by introducing common data formats and providing adapters through which the applications could talk to the ESB.
But the ESB still suffered two major drawbacks:
- Scalability: The ESB was a heavy piece of middleware that required a specialization to work with. The scalability of the ESB was hard due to the sheer amount of resources required to scale the bus, and this was even harder when the bus...
