SIA Module 4

Enterprise Service Bus

Enterprise Service Bus

A software platform utilized in the process of distributing work across connected application components.

Enterprise Service Bus

Intended to provide uniform method of moving messages based on the message content and business policies imposed

Enterprise Service Bus

Acts as a collection of switches that can guide messages

Enterprise Service Bus

Core of application processes

Enterprise Service Bus

An ___ does not mandate the location of components or the programming language, nor does it impose any constraints on those language. Instead, it serves the purpose of unifying the numerous communication channels.

Enterprise Service Bus

Can provide load balancing, which means that the performance of a component can be improved by instantiating several copies

Enterprise Service Bus

Layer of abstraction is provided to take advantage of the services provided

Enterprise Service Bus

Encourages loose coupling between services by demonstrating the abstraction of SOA endpoints

EAI

A framework for integration that maybe utilized in order to combine a collection of computer systems. It is a wide notion that covers patterns of integration. Does this by defining a set of integration principles and middleware.

EAI

The Concept

ESB

The Tool

EAI

An overarching framework for combining a collection of systems. Often uses a hub-and-spoke model.

ESB

Infrastructure software that implements EAI. Acts as a distributed broker between services.

Application Integration

Message Routing & Mediation
Service Orchestration & Choreography

Protocol & Format Conversion

Error Handling & Monitoring

Security & Governance

Core Application and Benefits of ESB

Application Integration

Linking CRM, ERP, and HR for real-time synchronization.

Message Routing & Mediation

Delivering messages based on business rules or conditions.

Service Orchestration & Choreography

Facilitate service delivery to carry out complicated business processes.

Protocol & Format Conversion

Translating protocols (SOAP to REST) or formats (XML to JSON).

Error Handling & Monitoring

Has the ability to record and report error message and perform quick fixes.

Security & Governance

Message-level encryption and authorization enforcement.

Message Brokers

Message transformers

Message Routing and Mediation

Service Adapters

Message Queues

Message Transformation Engines

Monitoring Tools

ESB Architecture and Components

Message Brokers

Intermediaries for receiving/transmitting messages.

Message Transformers

Data transformation across distinct formats (XML/JSON).

Message Routing and Mediation

Task of delivering and routing messages making use of predetermined rules.

Service Adapters

Standardized interfaces to interact with backend systems.

Message Queues

Facilitate asynchronous communication; store messages until the receiver is ready

Message Transformation Engines

Responsible for complex data transformation and mapping between various data.

Monitoring Tools

Visibility into performance, health, and activity.

Apache Camel

An open-source integration framework based on Enterprise Integration Patterns (EIP)

Apache Camel

Frequently utilized in various enterprise interprise scenarioes for message routing and transformation.

Apache Camel

It offers comprehensive selection of connectors.

Spring Integration

A lightweight framework that was built on top of the Spring framework, and implements event-driven architectures.

Spring Integration

Abstractions for event handling, message channels, and asynchronous flows are provided by it.

Spring Integration

Ideal for when an event-driven communication pattern can be implemented on a system that is built on microservices with publish-subscribe approach using Spring Integration.

Configuration and Management

Monitoring and Alerting

Security and Access Control

Performance Optimization

Deployment and Management

Configuration and Management

Equipped with Centralized Management Console for monitoring message flows.

Monitoring and Alerting

Monitoring KPIs, establishing alerts and notifications for real-time visibility.

Security and Access Control

Offer support for RBAC; ensures only users with permission can gain access.

Performance Optimization

Connection pooling, caching, and resource tuning to improve efficiency.
