Difference Between SOA and ESB

SOA is more related to boundary / integration interaction between systems. So if system A exposes services using a SOA I can interact with those services from system B. An ESB on the other hand is a technical implementation that aids in delivering a SOA. SOA is service oriented architecture .

What is the role of ESB in SOA?

The Enterprise Service Bus (ESB) is a software architecture which connects all the services together over a bus like infrastructure. It acts as communication center in the SOA by allowing linking multiple systems, applications and data and connects multiple systems with no disruption.

Is Kafka a ESB?

Apache Kafka and Enterprise Service Bus (ESB) are complementary, not competitive! Apache Kafka is much more than messaging in the meantime. It evolved to a streaming platform including Kafka Connect, Kafka Streams, KSQL and many other open source components. Kafka leverages events as a core principle.

What is the difference between SOA and Microservices?

The main difference between SOA and microservices: Scope

To put it simply, service-oriented architecture (SOA) has an enterprise scope, while the microservices architecture has an application scope. Many of the core principles of each approach become incompatible when you neglect this difference.

What is difference between SOA and API?

Difference Between APIs and SOA

While APIs are generally associated with REST/JSON and SOA is associated with XML and SOAP, SOA is more than just a protocol. SOA stands for “Service Oriented Architecture” and is an architectural best practice around building de-coupled applications and fosters service re-use.

Why do we need ESB?

Increasing organizational agility by reducing time to market for new initiatives is one of the most common reasons that companies implement an ESB as the backbone of their IT infrastructure. An ESB architecture facilitates this by providing a simple, well defined, "pluggable" system that scales well.

How do you implement ESB?

Enterprise Integration Map

1. Build a Data Integration Strategy.
2. Develop a Comprehensive Business-to-Business Integration Strategy.
3. Implement Your ESB Using a Stepwise Approach.
4. Build Effective Enterprise Integration on the Back of Business Process.
5. Implement and Optimize Application Integration Governance.

Can Kafka replace ESB?

Apache Kafka: An Open Source Event Streaming Platform

Integration and Stream Processing are still key functionality but can be realized in real time natively instead of using additional ETL, ESB or Stream Processing tools.

Is Kafka a middleware?

Apache Kafka is an open source stream processor that can be used as a message broker as well. Kafka provides low end-to-end latency with exceptional durability (persistence). It's a popular middleware tool.

What is ESB architecture?

An Enterprise Service Bus (ESB) is fundamentally an architecture. It is a set of rules and principles for integrating numerous applications together over a bus-like infrastructure. ESB products enable users to build this type of architecture, but vary in the way that they do it and the capabilities that they offer.

Are Microservices RESTful?

Microservices: The individual services and functions – or building blocks – that form a larger microservices-based application. RESTful APIs: The rules, routines, commands, and protocols – or the glue – that integrates the individual microservices, so they function as a single application.

Why did SOA fail?

SOA services are much larger in scope, have more interdependencies, and communication and data storage are handled outside the services. This requires the entire application to be rebuilt and redeployed, leading to slow deployment times and cascading failures.

Which SOA principles are applied in Microservices as well?

“Bounded Context” - SOA encourages sharing of components, whereas microservices try to minimize on sharing through “bounded context.” A bounded context refers to the coupling of a component and its data as a single unit with minimal dependencies.
