Integrating ROSA Applications with AWS Services (CS221)

In today's rapidly evolving cloud-native landscape, enterprises are looking for scalable, secure, and fully managed Kubernetes solutions that work seamlessly with existing cloud infrastructure. Red Hat OpenShift Service on AWS (ROSA) meets that demand by combining the power of Red Hat OpenShift with the scalability and flexibility of Amazon Web Services (AWS).

In this blog post, we’ll explore how you can integrate ROSA-based applications with key AWS services, unlocking a powerful hybrid architecture that enhances your applications' capabilities.

📌 What is ROSA?

ROSA (Red Hat OpenShift Service on AWS) is a managed OpenShift offering jointly developed and supported by Red Hat and AWS. It allows you to run containerized applications using OpenShift while taking full advantage of AWS services such as storage, databases, analytics, and identity management.

🔗 Why Integrate ROSA with AWS Services?

Integrating ROSA with native AWS services enables:

Seamless access to AWS resources (like RDS, S3, DynamoDB)

Improved scalability and availability

Cost-effective hybrid application architecture

Enhanced observability and monitoring

Secure IAM-based access control using AWS IAM Roles for Service Accounts (IRSA)

🛠️ Key Integration Scenarios

1. Storage Integration with Amazon S3 and EFS

Applications deployed on ROSA can use AWS storage services for persistent and object storage needs.

Use Case: A web app storing images to S3.

How: Use OpenShift’s CSI drivers to mount EFS or access S3 through SDKs or CLI.

spec:

  accessModes:

    - ReadWriteMany

  storageClassName: efs-sc

  resources:

    requests:

      storage: 5Gi

2. Database Integration with Amazon RDS

You can offload your relational database requirements to managed RDS instances.

Use Case: Deploying a Spring Boot app with PostgreSQL on RDS.

How: Store DB credentials in Kubernetes secrets and use RDS endpoint in your app’s config.

env

Copy

Edit

SPRING_DATASOURCE_URL=jdbc:postgresql://<rds-endpoint>:5432/mydb

3. Authentication with AWS IAM + OIDC

ROSA supports IAM Roles for Service Accounts (IRSA), enabling fine-grained permissions for workloads.

Use Case: Granting a pod access to a specific S3 bucket.

How:

Create an IAM role with S3 access

Associate it with a Kubernetes service account

Use OIDC to federate access

4. Observability with Amazon CloudWatch and Prometheus

Monitor your workloads using Amazon CloudWatch Container Insights or integrate Prometheus and Grafana on ROSA for deeper insights.

Use Case: Track application metrics and logs in a single AWS dashboard.

How: Forward logs from OpenShift to CloudWatch using Fluent Bit.

5. Serverless Integration with AWS Lambda

Bridge your ROSA applications with AWS Lambda for event-driven workloads.

Use Case: Triggering a Lambda function on file upload to S3.

How: Use EventBridge or S3 event notifications with your ROSA app triggering the workflow.

🔒 Security Best Practices

Use IAM Roles for Service Accounts (IRSA) to avoid hardcoding credentials.

Use AWS Secrets Manager or OpenShift Vault integration for managing secrets securely.

Enable VPC PrivateLink to keep traffic within AWS private network boundaries.

🚀 Getting Started

To start integrating your ROSA applications with AWS:

 Deploy your ROSA cluster using the AWS Management Console or CLI

 Set up AWS CLI & IAM permissions

 Enable the AWS services needed (e.g., RDS, S3, Lambda)

 Create Kubernetes Secrets and ConfigMaps for service integration

 Use ServiceAccounts, RBAC, and IRSA for secure access

🎯 Final Thoughts

ROSA is not just about running Kubernetes on AWS—it's about unlocking the true hybrid cloud potential by integrating with a rich ecosystem of AWS services. Whether you're building microservices, data pipelines, or enterprise-grade applications, ROSA + AWS gives you the tools to scale confidently, operate securely, and innovate rapidly.
