Why ESBs are your answers to integration and connectivity drawbacks

In the modern industry context, connecting systems and processes has become a key business imperative today. Within this interconnecting scope comes the complexity which can often cause havoc on enterprises if remained unchecked. However, validating if something is complex or not isn’t necessarily a standalone justification for change, what matters is whether or not these interconnected systems and processes run the way that they should. Therefore, the technologies that facilitate this integration are fast emerging as the No.1 priority for most enterprises. 

Introducing Enterprise Service Bus: 

The recent rise in utilizing an Enterprise Service Bus or ESB has taken its peak with the increase in demand for application integrations across organizations. As of 2020, it was estimated that the ESB market was valued at USD 0.8 billion and is expected to reach USD 1.2 billion by 2026 with a Cumulative Annual Growth Rate of 7.05%. As of now, North America has taken the leading role as the largest market for ESB utilization, while Asia Pacific has been considered as the fastest growing market with End-user industries such as IT, Telecom, Healthcare, and BFSI utilizing this platform. 

Enterprise Service Bus – a brief explanation: 

In comparison to a P2P architecture, an ESB can eliminate a number of pain points a P2P provides. In order to understand the concept of an ESB, it is better to first recognize its predecessor, Point to Point or better known as P2P. 

In the context of P2P, the applications recognize one another exclusively, which means the applications recognize each other’s data models and capabilities. These tightly coupled applications would seem fine if it were between a small number of applications. However, as the number of applications scales up, the infrastructure becomes delicate, difficult to maintain and thereby prone to failure. The primary reason behind this is due to its everchanging infrastructure style whenever new applications are introduced which becomes very complex in the long run. The real value of ESB architectures shows limelight by eliminating these P2P pain points.  

An ESB is a standardized integration, which consists of a combination of messaging, web services, data transformation, and routing, that would coordinate the interaction of heterogenous applications through a bus-like infrastructure. In simple terms, the applications are indirectly connected through the ESB, rather than being directly connected to one another. The ESB is responsible for all the embedded logics for distributing information across an enterprise quickly and ensuring the smooth delivery of information. 

This in turn benefits the scope for a flexible integration, thereby eliminating the need for custom coding and providing a centralized management of application
