Modernize Your API Layer Without Re-Architecture
APIs are no longer just connectors between applications—they’re central to digital transformation. From enabling real-time decisions to powering modern user experiences, APIs play a critical role in hybrid and multi-cloud architectures.
Yet, as API ecosystems grow in complexity, organizations face new challenges:
- How to secure APIs across environments
- How to minimize latency
- How to govern APIs centrally, without routing traffic outside their infrastructure
This is where Anypoint Flex Gateway on IBM Power delivers a strategic advantage. It allows enterprises to run, secure, and scale APIs close to the workloads—without migrating or rearchitecting mission-critical systems.

What Is Anypoint Flex Gateway?
Anypoint Flex Gateway is MuleSoft’s high-performance, lightweight API gateway. Designed for both containerized and VM-based deployments, it provides:
- Enterprise-grade API security
- Centralized governance and monitoring
- Low-latency execution at the infrastructure edge
When deployed directly on IBM Power Systems, Flex Gateway enhances API traffic handling by eliminating unnecessary hops, improving performance, and reducing security risks.
Why Deploy Flex Gateway on IBM Power?
Many enterprise applications—such as ERP, transaction engines, or AI models—run on IBM Power Systems. Routing their API traffic through external gateways often introduces performance bottlenecks or compliance risks.
Deploying Flex Gateway natively on IBM Power offers significant advantages:
- High-throughput processing with local API execution
- Reduced latency for mission-critical services
- Secure, isolated traffic handling within the Power environment
- Full control and lifecycle management via Anypoint Platform
This approach gives organizations the ability to modernize without disruption, gaining all the benefits of an advanced API gateway—right where their systems already run.
Key Benefits
Seamless Integration with Existing Infrastructure
- Runs natively on Red Hat Enterprise Linux (RHEL)
- Supports Red Hat OpenShift for container orchestration
- Installs easily with minimal configuration or downtime
Enterprise-Grade API Security and Governance
- Enforce OAuth 2.0, JWT validation, and rate limiting
- Apply consistent policies across internal and external APIs
- Use Anypoint Platform for centralized governance, visibility, and control
Optimized Performance and Reliability
- Avoids unnecessary network hops
- Maintains high-speed execution for real-time APIs
- Inherits IBM Power’s 99.999% uptime and workload isolation features
Step-by-Step: How to Deploy Flex Gateway on IBM Power
- Prepare the Environment:
- Ensure the system runs on RHEL or OpenShift
- Validate CPU, storage, and network configurations
- Download and Install Flex Gateway:
- Retrieve the latest build from MuleSoft
- Use YUM or Docker to install and deploy
- Register with Anypoint Platform:
- Connect the gateway to your control plane using CLI
- Enable API visibility and centralized control
- Configure APIs and Security Policies:
- Use YAML files or the API Manager UI
- Define routes, enforce policies, and enable rate limiting
- Optionally, develop custom policies using the Policy Development Kit (PDK)
- Monitor and Scale:
- Leverage Anypoint Monitoring for traffic analysis and troubleshooting
- Scale horizontally using OpenShift orchestration
Key Use Cases: Where Flex Gateway on IBM Power Excels
- Financial services: Real-time payment processing and transaction validation
- Manufacturing: Secure integration between legacy ERP and modern analytics tools
- Retail: Fast, secure APIs for live inventory, checkout, and loyalty systems
- Healthcare: Localized handling of sensitive patient data and compliance-bound APIs
In each scenario, running the gateway directly on IBM Power ensures minimal latency, stronger security, and seamless orchestration.
IBM Power: A Trusted Foundation for API Workloads
