For two decades, the ERP conversation was largely an ERP-selection conversation. Pick NetSuite, SAP, Dynamics, or Oracle, build the business around it, and treat every other system as a satellite that ultimately needs to connect to the ERP.
That model is changing.
The modern enterprise increasingly runs on a constellation of best-of-breed applications: a CRM, CPQ platform, warehouse management system, e-commerce storefront, billing engine, data warehouse, and increasingly, AI-powered applications and agents working across the technology stack.
This is the shift from monolithic ERP toward composable ERP—and it changes what “integration” means.
In a monolithic environment, integration is often treated as a project. In a composable environment, integration becomes infrastructure.
That distinction is where an iPaaS (Integration Platform as a Service) such as Celigo moves beyond being simply “the tool that connects Salesforce to NetSuite” and starts to function as a control plane for enterprise integration.
The Architectural Fork in the Road
Enterprises designing their technology architecture today generally encounter two broad approaches.
1. Centralized ERP as the Hub
In this model, the ERP—or a heavily customized ERP environment—attempts to own as much business logic and data as possible.
Point-to-point integrations, scripts, APIs, and custom middleware connect the ERP to surrounding applications.
This approach can work well when the technology landscape is relatively small and stable.
But as the application ecosystem grows, complexity grows with it. Every new application can introduce another integration, another credential, another dependency, and another component that needs to be monitored and maintained.
The result can be an increasingly difficult-to-manage network of connections.
2. Composable Architecture with an Integration Layer
The second approach separates application capabilities from integration and orchestration.
Instead of making the ERP the center of every workflow, organizations introduce a dedicated integration layer that connects the ERP with the rest of the application ecosystem.
The architecture becomes:
Business Applications → Integration Layer → ERP / Data / AI / Other Systems
The ERP remains a critical system of record, but it is no longer responsible for being the architectural center of the entire enterprise.
The integration layer becomes responsible for coordinating how applications exchange data and participate in cross-system processes.
This is where an iPaaS such as Celigo can play a strategic role.
The benefit isn’t simply fewer integrations. It is the ability to establish a consistent operating model for integration, orchestration, monitoring, error handling, and governance.
Why iPaaS Is Becoming the Integration Backbone
Several forces are pushing organizations toward an integration-layer model.
SaaS Sprawl
Modern businesses increasingly depend on dozens—and sometimes hundreds—of SaaS applications.
No ERP platform, regardless of how broad its suite becomes, is likely to be the native home for every specialized business capability.
An integration layer provides a way to connect this growing application landscape without forcing every business process into a single platform.
Speed of Change
Business teams can adopt, replace, or expand applications much faster than traditional IT development cycles can accommodate.
A centralized integration architecture can make the addition of a new application more repeatable by providing reusable integration patterns, connectors, mappings, and workflows.
The goal isn’t to make every new integration a simple configuration change. The goal is to reduce the amount of custom engineering required to connect and operate systems at scale.
Data Consistency
Finance, sales, operations, supply chain, and customer service often depend on the same underlying business information.
Customer records, orders, inventory, products, payments, and fulfillment information may need to move between multiple systems.
An integration layer can enforce defined synchronization rules and provide visibility into whether those workflows are succeeding.
This is particularly important when businesses require data to move between systems in near real time.
Where Celigo Fits
An iPaaS designed for enterprise application integration can provide the connectivity and orchestration layer required to support a composable architecture.
Celigo is an example of this approach.
Instead of treating integration as a collection of isolated connections, organizations can use an integration platform to establish reusable patterns for connecting ERP, CRM, e-commerce, marketplaces, data platforms, and other business applications.
A simplified architecture might look like:
Shopify → Celigo → ERP
CRM → Celigo → ERP
ERP → Celigo → Data Warehouse
Marketplace → Celigo → ERP → Fulfillment
The important architectural change is that the integration layer becomes the place where these cross-system flows are designed, monitored, and managed.
Celigo as the Enterprise Control Plane
The term control plane is useful because it describes the strategic role an integration platform can play.
In this context, the control plane is not necessarily the place where every piece of business logic lives. Instead, it is the layer where organizations can centralize integration orchestration, monitoring, transformation, governance, and operational visibility.
A mature integration control plane should help organizations answer questions such as:
- Which applications are connected?
- Which business processes depend on each integration?
- Where is data being transformed?
- Which workflows have failed?
- Who owns a failed integration?
- Can failed transactions be retried or recovered?
- How are integrations monitored across the environment?
- How quickly can a new application be connected?
This distinction separates an integration platform from a collection of independent scripts.
A collection of scripts may move data.
A control plane provides visibility and operational governance over how data and processes move across the enterprise.
Celigo vs. Jitterbit: Comparing Integration Approaches
The Celigo vs. Jitterbit discussion is best approached as an architectural comparison rather than a simple feature checklist.
Both platforms address enterprise integration, but organizations should evaluate them against their specific application landscape, integration complexity, technical resources, and long-term architecture.
| Consideration | Celigo | Jitterbit |
|---|---|---|
| Integration approach | Strong focus on application integration and business-process automation | Integration combined with API management and broader connectivity |
| Typical evaluation criteria | Application coverage, reusable flows, business-process automation, ease of implementation | Integration flexibility, API capabilities, customization, and connectivity |
| Target environment | Organizations looking for repeatable integration patterns across common SaaS and ERP applications | Organizations with diverse application environments and more customized integration requirements |
| Key architectural question | How quickly can common enterprise processes be standardized and operated? | How much flexibility and customization does the integration architecture require? |
Neither platform is universally “better.”
The right choice depends on factors such as the applications an organization already uses, the complexity of its workflows, the technical skills of its integration team, governance requirements, and the degree of customization required.
The broader architectural point remains important: when an organization adopts an iPaaS as its integration layer, it is making a deliberate decision to centralize integration orchestration and operational management rather than embedding every connection inside individual applications.
The Connector Ecosystem Is a Strategic Differentiator
It is tempting to evaluate iPaaS platforms based primarily on their flow-building interfaces.
The more durable question is whether the platform can reliably connect the systems the business actually operates.
A mature connector should do more than establish a basic API connection.
It should ideally:
- Understand the target application’s data and object model.
- Simplify authentication and credential management.
- Account for API limitations and operational requirements.
- Provide meaningful error handling and monitoring.
- Support transformations and field mappings.
- Be maintained as the underlying application’s APIs evolve.
- Provide reusable patterns for common business processes.
This is where the connector ecosystem becomes strategically important.
If an organization regularly integrates ERP, CRM, e-commerce, finance, logistics, and data platforms, the quality and breadth of those connections can directly affect implementation speed and ongoing maintenance effort.
What This Means for ERP Integration Tools
The category of ERP integration tools is evolving.
Historically, ERP integration largely meant connecting the ERP to a handful of adjacent applications.
Today, the integration platform increasingly needs to support an entire ecosystem.
That raises four strategic questions.
Where Should Cross-System Logic Live?
Should a particular workflow be controlled by the ERP, CRM, CPQ platform, or integration layer?
A composable architecture encourages organizations to separate application-specific functionality from cross-application orchestration.
The integration platform can coordinate processes that span multiple systems while allowing individual applications to focus on their core capabilities.
How Should New Systems Be Onboarded?
In a heavily customized ERP architecture, introducing a new application can mean developing additional custom integrations.
With a centralized integration layer, organizations can establish reusable patterns for connecting new applications and implementing common workflows.
This doesn’t eliminate integration work, but it can make that work more standardized and repeatable.
Who Enforces Data Synchronization?
Different applications may contain different representations of the same business entity.
The integration layer can enforce defined synchronization rules that keep information aligned across systems.
The goal isn’t for the integration platform to become the source of truth for every data domain. Instead, each domain can retain its authoritative system while the integration layer manages how that information is synchronized.
How Resilient Is the Architecture to Vendor Change?
Technology landscapes change.
Organizations replace CRMs, adopt new commerce platforms, migrate ERP systems, or introduce new data and AI technologies.
When integration logic is tightly embedded inside individual applications, these changes can become expensive and disruptive.
A dedicated integration layer can provide greater separation between applications, potentially reducing the impact of replacing individual components.
The Role of Integration in AI-Enabled Enterprises
The importance of the integration layer becomes even more apparent as organizations adopt AI agents and intelligent automation.
Consider an AI agent that needs to:
- Identify a customer.
- Retrieve customer and order information.
- Check inventory.
- Determine eligibility or pricing.
- Create or update an order.
- Update the CRM.
- Trigger fulfillment.
- Record the transaction in the ERP.
The AI may provide the reasoning and interaction layer, but the underlying actions still need to occur within trusted enterprise systems.
This creates a critical architectural requirement:
AI needs governed access to enterprise applications.
The integration layer can provide the pathways through which AI-driven processes interact with ERP, CRM, commerce, data, and other systems.
That makes iPaaS increasingly relevant to AI architecture—not because the integration platform replaces AI, but because it can connect AI capabilities to the systems where business transactions actually happen.
When a Centralized Integration Layer Makes Sense
A centralized integration layer isn’t automatically the right answer for every organization.
Organizations should consider factors such as:
- The number and diversity of applications.
- Integration volume and complexity.
- The amount of custom development already in place.
- Governance and monitoring requirements.
- The frequency with which applications change.
- The technical capabilities of the internal team.
- Requirements for real-time or event-driven integration.
For a small environment with only a few stable applications, direct integrations may be perfectly reasonable.
As the application landscape becomes larger and more interconnected, however, the value of centralized integration governance tends to increase.
Composable ERP and Centralized Integration Are Not Opposites
The debate between composable ERP and centralized integration can create a false choice.
Organizations don’t necessarily need to choose between a flexible application architecture and centralized integration.
They can use both.
- Composable applications provide flexibility.
- The ERP provides a system of record for core business transactions.
- The integration layer provides connectivity and orchestration.
- Data platforms provide analytics and enterprise insight.
- AI applications provide new ways to interact with enterprise capabilities.
Together, these components create a more flexible architecture than relying on a single application to perform every function.
The Strategic Takeaway
Composable ERP isn’t a rejection of ERP.
It is a rejection of the idea that the ERP must define the architecture of the entire enterprise.
The ERP remains critical for financials, transactions, and core business processes. But as organizations adopt more specialized applications, the architecture connecting those applications becomes increasingly important.
That’s where an iPaaS can become strategic.
Platforms such as Celigo can provide a centralized layer for connecting applications, orchestrating workflows, managing transformations, monitoring integrations, and establishing operational governance.
Whether an organization ultimately chooses Celigo, Jitterbit, or another iPaaS, the larger architectural question is the same:
Are you treating integration as a collection of projects—or as permanent enterprise infrastructure?
Organizations that make integration a strategic architectural layer can be better positioned to adopt new applications, connect emerging AI capabilities, and evolve their ERP ecosystem without rebuilding every integration from scratch.
That is the real promise of the composable model.
The ERP remains important.
But the integration layer increasingly determines how effectively the entire technology ecosystem works as one business.
