IBM Cloud Pak for Integration (IBM Integration Software)
Keep Your Core. Modernize How Everything Connects to It.
Your mainframe, ERP and policy systems still run the business well. What holds you back is the tangle of one-off connections around them. IBM Cloud Pak for Integration is the layer that fixes that: one platform for APIs, messaging, events, files and app-to-app flows, where you pick the right pattern for each connection instead of forcing everything through one. You modernize around the core, not through it.
Cloud Pak for Integration Is a Toolbox, Not a Single Product
Here is the part most vendors skip. The Cloud Pak itself does not integrate anything. The technologies inside it do the work.
What CP4I gives you is one platform and one control plane that bundle IBM’s integration products together, so you run them as a set instead of buying and operating each one separately. You choose the blocks your connections actually need, and add more when the work calls for it. That is the real value: standardize how integration is built and operated, and keep your options open on how each system connects.
The Technologies Inside CP4I, and What Each One Does
Eight building blocks, grouped by the job they do. Most estates start with two or three and grow from there.
API management
Turn systems into secured, managed APIs that channels, partners and apps reuse. Create, secure, socialize and version across the full lifecycle.
Application integration
Connect SaaS and on-prem apps with low-code flows, prebuilt connectors and AI-assisted mapping. Less custom glue code to maintain.
Enterprise messaging
Move business-critical messages once and only once, in order, even when a system is down. The backbone for payments, orders and transactions.
Event streaming
Publish and consume high-volume events in near real time, so downstream systems react as things happen instead of overnight.
Event APIs and processing
Catalog Kafka topics like APIs so teams can find and subscribe to them, and turn raw streams into real-time insight.
High-speed file transfer
Move large files and datasets across sites and clouds at speed and reliably, over any distance, where normal transfer stalls.
Security gateway
Enforce security, policy and traffic control at the edge of the integration, usually sitting in front of your APIs.
Unified management
Design, deploy and monitor every integration in one place, and reuse governed assets across teams instead of rebuilding them.
Five Integration Styles, One Platform
Every connection is a design choice. CP4I covers the main styles, so you match the pattern to the problem instead of bending one tool to every job.
Expose core services as governed APIs
Digital channels and partners need controlled access to core systems, and today every team builds its own connection. Nobody has a single view of who is calling what.
Use case: a bank exposes core account services as governed APIs, so mobile, web and partners consume one secured interface instead of a dozen point-to-point links.
React to change in near real time
Systems find out about changes too late because updates move in overnight batches. By the time one system knows, the customer already noticed the gap.
Use case: a retailer streams stock and order events as they happen, so pricing, fulfillment and the customer app all react the moment something changes.
Never lose or double-process a transaction
A payment or an order cannot be lost or processed twice, even when a system goes down mid-transaction. Best-effort connections are not good enough here.
Use case: an insurer moves policy and payment transactions over IBM MQ, with guaranteed once-only delivery between the core and downstream systems.
Stop re-keying data between systems
SaaS tools and legacy apps do not share data, so staff copy it by hand and two reports never quite agree. Every new tool adds another manual step.
Use case: a manufacturer connects Salesforce, an ERP and a legacy order system with low-code flows, so a new order runs end to end without anyone re-typing it.
Move large files and partner data reliably
Big files and partner exchanges run on scripts and FTP that fail quietly and cannot be traced. When a transfer breaks at 2am, no one finds out until it matters.
Use case: a life-sciences firm moves large datasets between sites and partners on Aspera, fast and with a full audit trail, instead of brittle overnight FTP jobs.
What Works Together, and What Is a Choice
Two questions decide most integration designs: which tools combine, and which one to pick when several could do the job. This is where a toolbox needs an architect.
Built to work together
Blocks that are stronger as a pair.
- API Connect + DataPower. DataPower enforces security and traffic policy in front of the APIs that API Connect manages.
- Event Streams + Event Processing. Event Processing turns the raw streams from Event Streams into real-time insight.
- App Connect + API Connect. Expose an App Connect flow as a managed API, and an internal integration becomes reusable across teams.
- Event Endpoint Management + API Connect. Publish Kafka topics in the same portal as your APIs, so teams discover events and APIs in one place.
- MQ + Aspera. Messaging carries the transactions, Aspera moves the bulk files. Different jobs, same estate.
A design choice, not a default
Cases where picking one means not needing the other.
- MQ vs Event Streams. MQ for guaranteed, ordered delivery of transactions. Event Streams for high-volume events with many subscribers. Sometimes you run both.
- API vs messaging vs events vs file. The same data can move as a REST call, a message, an event or a bulk file. Latency, volume and reliability decide which fits.
- App Connect vs custom code. Low-code flows when speed and maintainability matter more than a hand-built integration.
Cloud Pak for Integration gives you the flexibility. Someone still has to design it well for your systems: the right pattern per connection, built and governed so it holds up. That is the part we do.
Safe Access to the Core, Without Replacing It
The strongest reason to standardize integration is not tidy architecture. It is that your core systems, whether that is IBM Z, IBM i or another transactional core, still run the business, and every new channel, AI project and automation has to reach them without making them fragile.
CP4I is the layer that gives new work safe, governed access to core services and data. You connect a stable core to modern channels, analytics and automation in small, controlled steps, instead of re-platforming everything at once. It is also where CP4I meets the other Cloud Paks, each with its own job around the same core.
Ad-hoc Connections vs. a Standardized Integration Platform
Why enterprise IT and operations leaders standardize integration on one platform instead of adding more point-to-point connections or one more single-purpose tool:
| Decision Dimension | Ad-hoc, Tool-by-Tool Integration | Multishoring on IBM Cloud Pak for Integration |
|---|---|---|
| Pattern per connection | One favorite tool gets forced onto every job, whether it fits or not. | API, messaging, event or file: the pattern is matched to each connection. |
| The core system | Reached through fragile custom links, or left untouched and worked around. | Reached through safe, governed access. The core stays authoritative. |
| Operations | Separate products, each with its own console, updates and skills. | One platform and control plane on OpenShift, one way to run it all. |
| Visibility and reuse | No shared view; the same integration gets rebuilt in three places. | Central monitoring and a governed asset repository teams reuse. |
| Engagement model | Open-ended scope with an unclear first outcome. | Starts with a bounded integration assessment and a measurable first pilot. |
Integration You Can Govern, Trace and Trust
Connecting two systems is the easy part. Keeping the whole estate governable as it grows is where most integration programs run into trouble. That is where we focus.
Reusable patterns & ownership
We agree on target patterns and clear ownership up front, so one local project does not quietly pile up new architectural debt.
Observability & error handling
Every flow is monitored and alertable. When something fails, you can see where and why, backed by our integration error-handling platform.
Boundary security & auditability
Gateway policy, encryption and access control at the edge, with the trace and evidence that risk, legal and compliance ask for.
Proven Enterprise Integration Outcomes
These are Multishoring integration projects across BizTalk, Azure and Oracle Health estates. They show how we standardize and modernize integration around a stable core. Cloud Pak for Integration is the IBM-native way we now deliver the same result.
90% Drop in Support Incidents at Pernod Ricard
We moved a global BizTalk document-exchange platform to a hybrid Azure architecture and added the iTrack error-handling tool, which cut the data chaos across the estate.
A Cloud Integration Strategy for Tikkurila & PPG
We migrated a BizTalk integration solution to Azure Logic Apps and realigned the data flows to a new business structure after the acquisition.
The Interface That Went Dark
A three-hospital health system replaced blind-spot monitoring with a single view of its Oracle Health interfaces, so failures get caught before they reach operations.
Start With a 10-Day Integration Assessment
A short, bounded assessment run by senior integration architects. We map your connections, match each one to the right pattern and the blocks that fit, and define the first safe change, all before you commit to any platform.
Interface & Estate Inventory
Catalog current connections, systems of record, partners and the flows that hurt most today.
Pattern & Block Fit
Match each connection to an integration style and the CP4I blocks that fit, and flag the design choices.
Target Architecture
Design the control-plane pattern, standards and ownership model for your estate.
Roadmap & Pilot Proposal
Deliver a prioritized modernization roadmap and a fixed-scope first pilot.
From Assessment to a Governed Integration Program
After the assessment, our senior teams deliver the roadmap in focused, measurable sprints. We prove the pattern on one connection before scaling it.
First Integration Pilot
Deliver one connection end to end on Cloud Pak for Integration, in the style that fits it. Prove the pattern against a real, measurable outcome.
Scale the API & Event Program
Build reusable APIs and event streams, onboard partners and channels, and retire the most fragile point-to-point links.
Governance & Handover
Standardize monitoring, error handling and boundary security, then transfer knowledge to your internal integration team.
“A Cloud Pak gives you options. The value shows up when someone maps those options to your systems. We pick the integration pattern for each connection, then build and govern it, so your core stays stable while everything around it moves faster.”

Frequently Asked Questions: IBM Cloud Pak for Integration
What is IBM Cloud Pak for Integration (now IBM Integration Software)?
It is IBM’s hybrid integration platform, recently renamed IBM Integration Software. Think of it as a toolbox rather than a single product: it puts API management, application integration, enterprise messaging, event streaming, high-speed file transfer and a security gateway on one platform and one control plane. It runs in containers on Red Hat OpenShift, on-premises or in any cloud, and you use the blocks your connections need.
What technologies are inside CP4I?
The main blocks are IBM API Connect (API management), IBM App Connect (application integration), IBM MQ (enterprise messaging), IBM Event Streams with Event Endpoint Management and Event Processing (event streaming), IBM Aspera (high-speed file transfer) and IBM DataPower Gateway (security). A shared Platform UI, integration assemblies and an asset repository let you design, run and reuse everything in one place.
Do we need all of the components?
No. That is the point of the toolbox. Most estates start with two or three blocks that match their most pressing connections, for example API management plus messaging, and add event streaming or file transfer later when a use case calls for it. You standardize the platform once and choose the tools per connection.
IBM MQ vs Event Streams: which do we need?
Use IBM MQ when a message must be delivered once, in order, and never lost, such as a payment or an order. Use Event Streams when you need to publish high-volume events that many systems subscribe to in near real time, such as stock or activity updates. They are different jobs, and plenty of estates run both. We help you decide per connection rather than defaulting to one.
How is CP4I different from an iPaaS like Boomi, MuleSoft or Azure Integration?
iPaaS platforms are strong for cloud and SaaS integration. Cloud Pak for Integration is built for enterprises that also need mission-critical messaging (IBM MQ), event streaming and high-speed transfer under one self-managed, hybrid control plane, often sitting close to a mainframe or regulated core. We work across both worlds. If you already run Azure, BizTalk, Boomi or Tibco, we modernize and coexist with it instead of forcing a replacement.
How does CP4I connect a legacy or mainframe core without replacing it?
CP4I exposes core functions as governed APIs, reliable messages and events, so new channels use the core without touching it. Your IBM Z, IBM i, ERP or policy core stays the source of truth. This is the Modern Mission Critical idea: keep the reliable core, give new work safe and governed access to it, and modernize around it in small steps.
How much faster is integration development on CP4I?
IBM markets Cloud Pak for Integration as delivering up to around 300% faster integration development, through low-code flows, reusable assets and AI-assisted design (IBM’s own figure, so treat it as a vendor benchmark, not a guarantee). Your result depends on your estate and how well the patterns are designed. In our own integration work, re-architecting a global estate cut support incidents by 90% at Pernod Ricard.
How does Multishoring deliver for US-based enterprise teams?
Our senior architects work in agile two-week sprints with four to six hours of daily overlap with US Eastern and Central working hours, transparent tracking, and dedicated PMO governance. We have US offices in New York, Philadelphia, San Francisco, Seattle, Chicago and Austin, with delivery centers in Europe.
