IBM Hybrid iPaaS Architecture
Our IBM Hybrid iPaaS architecture provides a unified control plane for managing integrations across cloud and on-premise environments sustainably.
Cloud Ecosystem
SaaS applications, cloud databases, and event streams running on IBM Cloud, AWS, or Azure.
Secure Hybrid Connectivity
VPN, Private Link, and secure tunnels ensure data moves safely between cloud and on-premise environments.
Unified Control Plane
A single design and management studio (webMethods/App Connect) orchestrates flows across all environments.
On-Premise Agents
Local agents and edge runtimes provide secure access to internal systems without exposing them to the internet.
On-Premise & Legacy Systems
ERP, legacy mainframes, and databases running in your data center, integrated via local runtimes.
Our IBM Hybrid iPaaS practice delivers a single control plane that unifies integration across cloud and on-premise environments. On the cloud side, we connect your SaaS applications — Salesforce, HubSpot, ServiceNow, Jira, Snowflake, Power BI, Workday, Stripe, and Kafka event streams — running on IBM Cloud, AWS, or Azure. On the on-premise side, we reach into your ERP systems like SAP and Oracle EBS, databases including Oracle, MSSQL, and DB2, legacy and mainframe systems like AS400, file and MFT transfers over SFTP and EDI, messaging through MQ, AMQP, and JMS, internal SOAP and REST APIs, and SCADA and IoT edge devices. Both sides are linked through secure hybrid connectivity — VPN, Private Link, TLS and mTLS, on-prem agents, API gateways, credential vaults, and firewall rules on the cloud side, and on-prem agents, edge runtimes, local Kubernetes, secure tunnels, DMZ proxies, data residency controls, and encryption at rest on the on-premise side. At the center sits the IBM Hybrid iPaaS control plane built on webMethods, Integration Server, Broker and Universal Messaging, API Gateway, MFT, IBM Cloud Pak, and App Connect — providing a unified design studio, runtime management across all environments, centralized monitoring and alerting, governance and data residency compliance, and a library of 200+ pre-built connectors, with CI/CD pipelines, error handling, versioning and rollback, RBAC and audit, auto-scaling, environment promotion, and health checks built in. The platform manages 150+ integrations at 99.9% availability, all running on Kubernetes, Docker, Terraform, Helm, GitOps, Prometheus, Grafana, and ELK stack infrastructure.
Our Approach
We design and implement hybrid integration platforms on the IBM stack — webMethods, Integration Server, Broker and Universal Messaging, API Gateway, MFT, IBM Cloud Pak, and App Connect — giving you a unified design studio, runtime management, and centralized monitoring across every environment from a single control plane. Integrations run where they need to: in the cloud on IBM Cloud, AWS, or Azure for your SaaS applications like Salesforce, ServiceNow, Workday, and Kafka event streams, or on-premise through edge runtimes, local Kubernetes, and on-prem agents for your ERP, databases, legacy and mainframe systems, messaging queues, and SCADA and IoT devices.
Both sides are connected through secure hybrid connectivity — VPN, Private Link, TLS and mTLS, credential vaults, DMZ proxies, secure tunnels, and data residency controls — with governance, RBAC, audit trails, and compliance policies enforced consistently across all environments. The control plane includes CI/CD pipelines, versioning and rollback, auto-scaling, environment promotion, error handling, and health checks, backed by a library of 200+ pre-built connectors — so your team delivers new integrations faster while managing 150+ integration flows at 99.9% availability with lower operational overhead.
Key Capabilities
Hybrid Architecture
Design cloud and on-premise runtime topology — placing integrations on IBM Cloud, AWS, or Azure for SaaS connectivity, and on edge runtimes, local Kubernetes, or on-prem agents for ERP, databases, legacy systems, messaging, and IoT devices.
Unified Design & Deploy
Build all integrations in a single webMethods design studio with deployment to any runtime — cloud or on-premise — using CI/CD pipelines, versioning and rollback, environment promotion, and auto-scaling across every environment from one control plane.
Connector Library & Adapters
Leverage a library of 200+ pre-built connectors and adapters to connect cloud CRM, SaaS apps, analytics and BI platforms, HCM systems, payment providers, event streams, on-premise ERP, databases, legacy and mainframe systems, messaging queues, file and MFT, internal APIs, and SCADA and IoT devices.
Connectivity & Security
Establish secure hybrid connectivity through VPN, Private Link, TLS and mTLS, on-prem agents, API gateways, secure tunnels, DMZ proxies, credential vaults, firewall rules, and encryption at rest — ensuring data moves safely between cloud and on-premise.
On-Premise & Legacy Integration
Reach into on-premise and legacy environments — SAP, Oracle EBS, AS400, mainframes, MSSQL, DB2, MQ, AMQP, JMS, SFTP, EDI, SOAP, and SCADA — through on-prem agents, edge runtimes, local Kubernetes, and secure tunnels without exposing internal systems to the internet.
Monitoring & Ops
Centralize monitoring, logging, alerting, and health checks across all cloud and on-premise runtimes — with error handling, RBAC, audit trails, and auto-scaling to maintain 99.9% availability across 150+ managed integrations.
Data Residency & Compliance
Control where data and processes run to meet residency, regulatory, and compliance requirements — with governance policies, data residency controls, encryption at rest, and audit trails enforced consistently across every environment.
Infrastructure & Platform
Run the hybrid iPaaS on enterprise-grade infrastructure with Kubernetes, Docker, Terraform, Helm, GitOps, Prometheus, Grafana, and ELK stack — supporting the full IBM stack including webMethods, Integration Server, Broker, Universal Messaging, API Gateway, MFT, IBM Cloud Pak, and App Connect.
How it Works
1. Event Triggers
An integration flow is triggered by an event — a change in a cloud SaaS application like Salesforce or ServiceNow, an incoming API call, a Kafka event stream message, a data change in an on-premise ERP or database, a file landing on an SFTP server, or a scheduled job. The trigger can originate from either the cloud or on-premise side.
2. Secure & Route
The request passes through the secure hybrid connectivity layer. Cloud-bound traffic uses VPN, Private Link, TLS and mTLS, API gateways, and credential vaults. On-premise-bound traffic routes through on-prem agents, secure tunnels, DMZ proxies, local Kubernetes runtimes, and firewall rules — ensuring data never traverses an unsecured path regardless of direction.
3. Orchestrate & Transform
The IBM Hybrid iPaaS control plane takes over — webMethods and Integration Server execute the integration logic, applying data mapping, transformation, enrichment, conditional routing, and error handling. The flow runs on whichever runtime is appropriate: a cloud instance on IBM Cloud, AWS, or Azure, or an on-premise Integration Server or edge runtime in your data center.
4. Deliver to Target
The processed data is delivered to the target system — an on-premise ERP like SAP or Oracle EBS, a database like Oracle, MSSQL, or DB2, a legacy mainframe or AS400, a messaging queue over MQ, AMQP, or JMS, a file transfer via MFT or SFTP, a cloud CRM, an internal SOAP or REST API, or a SCADA and IoT endpoint. The 200+ pre-built connectors handle protocol and format differences.
5. Govern & Comply
Every flow is governed throughout execution — RBAC controls who can design, deploy, and operate integrations, audit trails capture every action and data movement, data residency policies ensure workloads run in the correct jurisdiction, and versioning with rollback capabilities protect against deployment issues. Compliance is enforced consistently across cloud and on-premise environments.
6. Monitor & Scale
The entire platform is monitored through centralized dashboards with Prometheus, Grafana, and ELK stack — providing logging, alerting, and health checks across all runtimes. Auto-scaling adjusts capacity based on load, CI/CD pipelines manage deployment promotion across environments, and the platform maintains 99.9% availability across 150+ managed integration flows.

Frequently Asked Questions
Most enterprises run a mix of cloud SaaS applications and on-premise systems like ERP, databases, mainframes, and messaging queues that can't be moved to the cloud — whether for technical, regulatory, or cost reasons. A hybrid iPaaS gives you a single control plane to design, deploy, monitor, and govern integrations across both environments, rather than managing separate tools for cloud and on-premise. It also ensures data residency and compliance requirements are met without sacrificing connectivity.
The control plane is built on the full IBM integration stack — webMethods, Integration Server, Broker and Universal Messaging, API Gateway, MFT, IBM Cloud Pak, and App Connect. We select and configure the right combination based on your integration patterns, runtime requirements, and existing IBM investment. If you're already running parts of this stack, we unify and modernize them under a single control plane.
Yes — that's one of the core strengths of hybrid iPaaS. We connect to on-premise ERP systems like SAP and Oracle EBS, databases including Oracle, MSSQL, and DB2, legacy and mainframe systems like AS400, messaging queues over MQ, AMQP, and JMS, SFTP and EDI file transfers, internal SOAP and REST APIs, and SCADA and IoT edge devices. On-prem agents, edge runtimes, local Kubernetes, and secure tunnels reach these systems without exposing them to the internet.
We establish secure hybrid connectivity through multiple layers — VPN, Private Link, TLS and mTLS, on-prem agents, API gateways, secure tunnels, DMZ proxies, credential vaults, firewall rules, and encryption at rest. Data residency controls ensure workloads run in the correct jurisdiction, and all credentials are stored in vaults rather than integration code. The same security policies are enforced consistently on both the cloud and on-premise sides.
The architecture is designed for enterprise scale. Our reference deployments manage 150+ integration flows at 99.9% availability with auto-scaling, health checks, and centralized monitoring across all environments. The 200+ pre-built connectors accelerate delivery of new integrations, and CI/CD pipelines with versioning and rollback ensure changes are deployed safely as the platform grows.
Error handling is built into every layer. The control plane includes retry logic, dead-letter handling, alerting, and detailed logging for every flow. Centralized monitoring through Prometheus, Grafana, and ELK stack gives your team immediate visibility into failures across cloud and on-premise runtimes. Versioning and rollback capabilities let you revert a deployment quickly if a new release introduces issues.
Absolutely. The hybrid model supports runtimes running on your own infrastructure — on-premise Integration Servers, local Kubernetes clusters, and edge runtimes in your data center — all managed from the same unified control plane as your cloud runtimes. This is essential for workloads with data residency requirements, latency constraints, or systems that cannot be exposed externally.
An initial control plane setup with secure connectivity, core runtimes, and a first set of integrations typically takes 6–10 weeks. If you're already running parts of the IBM stack, we can unify and modernize the environment faster. After the platform is operational, new integrations are delivered incrementally — the 200+ pre-built connectors and CI/CD pipelines with environment promotion mean most new flows go live in days rather than weeks.
