Secure OCI Nifi Integration
Custom Processors for Secure Data Flows in DoD Environments
When Ikeda Innovations was engaged to support the buildout of the Oracle Cloud Infrastructure (OCI) environment—for DoD apps, we were tasked with delivering a suite of secure multi-tenant services to aid customers in their migration to the enclave.
A key service was Apache NiFi, a data processing platform widely used for enabling secure data workflows between isolated systems.
Among the top priorities for migrating systems was ensuring secure, recurring data transfer with on-premises systems, strictly over HTTPS on port 443.
NiFi’s visual design interface and powerful workflow automation capabilities made it the ideal fit for facilitating these data flows.
Tackling a Major Migration Hurdle Head-On
While running NiFi in Oracle Cloud Infrastructure (OCI) was relatively straightforward, a significant challenge emerged: unlike AWS and Azure, Nifi does not offer native processor support for OCI.
This gap created serious obstacles for setting up efficient, scalable, and automated data workflows.
Our customers needed to move data securely into their OCI Object Storage buckets, and this limitation threatened to undermine both our automation goals and deployment timelines.
We had to engineer a solution to bridge the gap.
Interim Integration Approach: Bridging NiFi and OCI with S3-Compatible Storage
As an initial workaround, we leveraged NiFi’s AWS S3 processors to interact with Oracle Cloud’s Object Storage Service.
Since Oracle supports S3-compatible APIs, this allowed us to use AWS SDKs and OCI Customer Secret Keys to enable data movement.
While this approach technically worked, and got data flowing, it came with several critical drawbacks:
- Lack of full feature parity with native OCI capabilities.
- Manual generation and rotation of long-lived access keys every 90 days; a challenge we also solved in our Terraform session-authentication approach.
- Environment-specific configurations, requiring keys to be manually updated in Nifi for each customer and deployment – introducing risk of human error and service disruption.
- Scalability concerns, as maintaining unique credentials across customers and environments became increasingly high maintenance and error-prone.
2i Solution: A Tailored NiFi Processor for OCI
Our customer shared our concerns about the limitations of the S3 compatible approach.
To address the concern, we enhanced Apache NiFi with our own processors specifically for Oracle Cloud (OCI). This solution directly addressed the shortcomings of the S3 approach by leveraging native Oracle authentication and APIs.
Our solution consisted of two main components:
1. Authentication / Authorization Layer: Leveraged Oracle’s concept of “Instance Principals” which allows for compute nodes to be authorized actors (or principals) to perform actions on OCI resources. Instance Principals use short-lived auto-rotating access keys with access governed by IAM policies and Dynamic Group association, strengthening security and improving operational efficiency.
2. Enhanced Java Processors and Services: Enabled secure, direct communication with Oracle Cloud services via native APIs. We built Controller Services to support authentication through the instance’s identity or OKE workload identity, and a handful of processors dedicated to supporting Object Storage operations.
With this setup, NiFi can interact with OCI services securely, automatically, and without credential rotation maintenance.
Tailored Solutions That Build Trust in Federal Cloud Integrations
Our customer quickly recognized the value of this solution.
Without internal Java development expertise, they appreciated that Ikeda Innovations could go beyond traditional infrastructure as code (IaC) support and delivered an enhanced solution.
This project was completed in under 2 sprints, alongside other active tasks—making it a high-impact, cost-effective enhancement with minimal disruption to ongoing operations.
Key Technical Gains for Federal IT: Secure, Automated, Extensible NiFi-OCI Integration
Beyond improved security and reduced manual work, the solution offered several other advantages:
- Performance Gains: A tailored processor could be tuned with OCI specific parameters, outperforming the generic AWS S3 workaround.
- Extensibility: The authentication framework we developed now allows us to build additional processors for other OCI services, such as the File System Service, which could further streamline on-prem to cloud data transfer workflows.
- Self-Reliance: As there are no public contributions to NiFi for OCI from Oracle, our solution ensures we’re not dependent on external sources or vendor timelines for new features.
- Enhanced Security aligned with federal compliance frameworks.
Innovating Beyond the Integration: Enabling Strategic Value in Federal Cloud Environments
This project became more than just a technical solution.
It exemplified toil reduction—a key initiative in federal engineering circles—by automating repetitive, manual tasks such as credential rotation or scheduled file transfers. It also promoted long-term sustainability and simplicity in cloud operations.
Our ability to innovate a purpose-built, automation-friendly solution —combining cloud engineering with our software development— positions Ikeda Innovations as a trusted, forward-thinking partner.
Tailored NiFi-OCI Integration that Builds Trust and Delivers Strategic Value
By developing a tailored Apache NiFi processor for Oracle Cloud, we didn’t just fix a feature gap—we delivered a scalable, secure automation solution that aligned with federal mission needs.
The project strengthened our relationship with our customer and opened new doors for OCI-based innovation.
At Ikeda Innovations, we believe strategic value comes from solving the right problems—and doing it in a way that builds long-term trust, operational capability, and strategic impact.
