A Modern Alternative to ESBs: Why Enterprises Are Moving to Operational Data Hubs

Sep 03,2025

From Process-Centric to Data-Centric Integration

For years, Enterprise Service Buses (ESBs) have been the standard solution for integrating enterprise systems, especially in SOA-driven environments. They provided a central hub to route messages, orchestrate services, and manage complex workflows.

But in the age of real-time applications, microservices, and customer-centric operations, traditional ESBs are falling short. Today’s businesses demand data-first, low-latency, and schema-aware integration — and that’s where Operational Data Hubs (ODHs) come in.

Why Traditional ESBs Fall Behind

Although ESBs were effective in the past, they pose serious limitations in today’s landscape:

High latency: ESBs are not built for real-time; most rely on message queues and batch processing
Tightly coupled interfaces: Changes in one service often break others
Complex governance: Managing message schemas, transformations, and routing rules becomes brittle
Limited data capabilities: No inherent support for change data capture (CDC), schema evolution, or analytics-driven consumption

As enterprises scale, maintaining ESB logic becomes a bottleneck for both development and innovation.

What Is an Operational Data Hub?

An Operational Data Hub is a modern integration layer designed to synchronize, transform, and serve operational data in real time.

Unlike ESBs, which are focused on services, ODHs focus on data — continuously integrating changes from multiple systems and making them available to downstream consumers such as APIs, microservices, dashboards, and AI models.

Head-to-Head: ESB vs Operational Data Hub

Feature	ESB	Operational Data Hub
Integration Focus	Process / services	Data / events
Latency	Minutes to hours	Milliseconds to seconds
Architecture	Centralized message bus	Streaming data pipelines
Adaptability	Static interface contracts	Schema-aware, flexible
Primary Use Cases	Workflow orchestration, SOA	Real-time sync, Customer 360, API data services
Example Tools	MuleSoft, WSO2, Tibco	TapData, Confluent, StreamSets

Real-Time Is the New Default

Business applications increasingly rely on real-time context:

Retail personalization engines need up-to-date customer data
Operations teams need live dashboards on inventory and supply chain
AI models need continuous data streams to improve performance

ESBs can’t keep up with these use cases. They weren’t designed to handle CDC-based streaming, incremental views, or materialized APIs.

Operational Data Hubs fill this gap.

How TapData Enables a Modern Data Hub Architecture

TapData offers a purpose-built platform for real-time operational integration:

Log-based CDC support for Oracle, MySQL, PostgreSQL, SQL Server, and more
Sub-second data sync pipelines to MongoDB, ClickHouse, Kafka, and API targets
Auto-refreshed materialized views for real-time dashboards and API delivery
Schema mapping and evolution handling built-in
No-code pipeline designer for fast deployment across legacy and modern systems

With TapData, enterprises can replace outdated ESBs with a scalable, data-centric integration fabric optimized for both operational use and analytics.

Migration Considerations

Thinking of moving away from an ESB? Consider the following steps:

Identify existing ESB flows that are data-dominant (e.g., syncing orders, customers, inventory)
Rebuild these flows as CDC-based pipelines in TapData
Replace hardcoded interfaces with API-ready materialized views
Monitor performance and validate with consumers before decommissioning ESB logic

This gradual approach allows for low-risk modernization, especially in enterprises with legacy infrastructure.

Summary: Replace Complexity with Speed and Flexibility

Traditional ESBs were built for an era of static systems and slow data. Today, agility, speed, and real-time insights are critical to business success.

An operational data hub offers the modern enterprise:

Lower latency
Easier maintenance
Greater data accessibility
Faster time to value

TapData helps teams move from process-first to data-first, giving you a platform to power everything from APIs to machine learning — in real time.
