These approaches did not simply replace one another. The enduring challenge is to connect the right systems across organizational boundaries while balancing shared contracts, change autonomy, workflow ownership, and lifecycle cost.
Why systems integration began as an enterprise problem
Integration is not just a matter of making two applications exchange data. Teams also need to agree on what information means, which processes it supports, who owns each side of an interface, and how changes will be governed. A technically functional connection can still fail organizationally if its assumptions do not match how the enterprise actually works.

NIST’s 1997 report, Standardization and Enterprise Integration (NISTIR 6049), made that relationship central: standards should reflect real enterprise processes. Its author, Jim G. Nell, warned, “If that is not done, the effort to produce the standards largely will be wasted.” The point is practical: standardization can make exchange more repeatable, but a standard that does not fit the work may not change how people or systems operate.
Manufacturing made the boundary visible
Manufacturing shows why shared terminology and explicit boundaries matter. The ISA-95 series was first published in 2000 to normalize integration between enterprise systems and control systems. ISA describes it as a framework for information exchange between manufacturing control functions and enterprise functions, with models and terminology intended to help manufacturing and IT personnel collaborate.

Chris Monchinski, identified by ISA as its 2019–20 Vice President of Standards & Practices, described ISA-95’s aim as “normalizing the integration practices between isolated enterprise and control systems and, in doing so, reducing costs and increasing success rates for these efforts.” That statement describes the standard’s intent; it is not a measured finding of a particular cost reduction or success-rate increase.
How integration approaches broadened
As systems and organizations became more distributed, integration became a question of architecture as well as data exchange. Different approaches put the shared contract, workflow logic, and responsibility for change in different places. The milestones below illustrate that broadening scope, not a single sequence in which each new method made its predecessor obsolete.
| Milestone | What it contributes | What it does not establish |
|---|---|---|
| NISTIR 6049 (1997) | Connects enterprise integration and standards to how organizations actually operate. | A specific integration protocol or product. |
| ISA-95 (first published 2000) | Provides manufacturing-oriented models and terminology for information exchange between enterprise and control functions. | A universal model for every industry. |
| IEEE 42020-2019 | Defines architecture processes for governance, management, conceptualization, evaluation, and elaboration across a lifecycle. | A specific integration protocol. |
| OASIS SOA Reference Architecture Foundation (approved December 2012) | Frames service-oriented architecture around views that include participation and ownership. | A requirement that every organization adopt the same service model. |
| Current cloud integration guidance | Shows how APIs, messaging, events, and orchestration can connect applications, data, services, and devices across on-premises, cloud, and edge environments. | A context-free ranking of patterns or a vendor-neutral product prescription. |
What service-oriented architecture added
Service-oriented architecture (SOA) shifted attention toward services and the ecosystems around them: who participates, who owns a service, and how services are realized and used. OASIS approved its Reference Architecture Foundation for SOA in December 2012. The Open Group’s OSIMM offers seven abstract levels of service-integration maturity, which organizations can use to describe a current state and discuss a transformation path.
A maturity model is an assessment aid, not a universal ranking of business quality. A higher level is not automatically the right destination for every organization; the useful question is whether a particular capability addresses a real need, such as reducing unwanted dependencies or clarifying service ownership.

How APIs, cloud workflows, messaging, and events fit together
Modern cloud integration guidance treats integration as a mix of interaction patterns rather than a choice of one technology for everything. A direct API call can fit a process that needs an immediate request and response. Messaging or events can fit work that can be handled asynchronously. Orchestration provides a way to define and run workflow logic.
Microsoft’s basic Azure reference architecture illustrates one vendor-specific implementation: Logic Apps orchestrates workflows, while API Management publishes and catalogs APIs. The example also documents importing OpenAPI-described web services and SOAP APIs. It is an example of how current tools can connect newer and existing interfaces, not a recommendation that Azure is the default platform.
Choose the interaction pattern by the work
| Pattern | Useful question | Trade-off to examine |
|---|---|---|
| Point-to-point link | Is this a narrow connection between two known systems? | How many dependencies and separate changes will accumulate as more systems connect? |
| Service-oriented design | Should a capability be exposed for participation by multiple consumers? | Who owns the service, its contract, and the changes consumers must accommodate? |
| Direct API call | Does the caller need a response immediately to continue? | How tightly are availability, response time, and release changes coupled between caller and provider? |
| Messaging or event handling | Can work be processed asynchronously, or should multiple consumers react to a change? | Who handles the workflow and its operational responsibilities across producers and consumers? |
| Orchestration | Does a workflow need an explicit place to define and run its steps? | Which team owns that logic, and how will it evolve with the systems it coordinates? |
These patterns can coexist in one environment. APIs do not automatically eliminate older middleware or web services, and events do not make synchronous calls unnecessary. A system may use a direct call for one interaction, an orchestrated workflow for another, and asynchronous messaging for work that does not require an immediate response.
What changed—and what did not
- The options expanded. Integration can be organized around standards, services, APIs, orchestration, messaging, and events, rather than treated as a single kind of connection.
- Ownership became an architectural concern. Service boundaries and workflow logic raise questions about who maintains contracts and coordinates change.
- Architecture became a lifecycle practice. IEEE 42020-2019 covers governance and evaluation as well as operation, sustainment, decommissioning, and disposal. Integration decisions therefore need to account for systems as they change and eventually retire, not only at initial design.
- The central coordination problem remained. Teams still need workable agreements about meaning, boundaries, responsibility, and change.
How to choose an integration approach
There is no context-free winner among point-to-point links, services, APIs, messaging, events, and orchestration. Before choosing, map the specific systems and organizational boundaries involved, then work through these questions:

Best Value
- What must be shared? Define the data, capability, or business outcome that needs to cross the boundary, and agree on its meaning.
- Who owns each side? Identify the teams responsible for the systems, shared contracts, workflow logic, and changes. Include participation and ownership in the design rather than leaving them implicit.
- When does the work need to happen? Decide whether the process needs an immediate request/response or can tolerate asynchronous handling. Choose the interaction pattern accordingly.
- Where should workflow logic live? Determine whether callers should contain it, an orchestrator should define it, or producers and consumers should coordinate through events.
- How much coupling is acceptable? Examine whether one system depends on another’s implementation, availability, or release schedule. A defined interface alone does not guarantee loose coupling.
- How will the design be maintained? Consider evaluation, operation, sustainment, and eventual retirement. For manufacturing, explicitly assess the boundary between enterprise and control functions and whether ISA-95’s domain-specific models apply.
The history of systems integration is therefore not a march toward one final architecture. It is the expansion of choices for sharing information and coordinating work, with standards and lifecycle governance helping those choices fit real organizational boundaries.
