Build secure applications with OpenShift 4.3 on public cloud
Example bank application highlights building secure cloud application with OpenShift 4
Building secure applications that ensure data privacy and security when deployed to a public cloud environment is crucial for businesses that collect customer data, particularly for regulated industries like finance, retail, banking, and others. In this article, I introduce you to an Example Bank application my team built to explore and share approaches for creating secure cloud-based applications with Red Hat OpenShift 4.3 on IBM Cloud.
Overview of the Example Bank application
See how the application works
Create an account (via IBM App ID) by using a generated name in the app’s dropdown. When you hit the home button of the app, you can click on the various app icons there to create credit card transactions.
Secure microservices application architecture
When building our Example Bank application, we had to keep public cloud security top of mind. The application is secured with HTTPS, and the interaction between the microservices is even encrypted with TLS via the OpenShift Service Mesh. Even the build pipeline for the application includes a scan of the codebase for security purposes.
The following diagram outlines the architecture of the software:

Use the open source code and instructions in the following content to understand the steps we followed to build the secure cloud application with OpenShift 4.3:
- Article: An introduction to OpenShift 4
- Article: Threat modeling in the context of microservice architectures
- Tutorial: Fun with OperatorHub
- Code pattern: Focus on data privacy with a back end for a mobile bank app
- Code pattern: Microservices with the OpenShift Service Mesh
- Tutorial: Build serverless Node.js applications with the OpenShift Serverless Operator
- Tutorial: Build a Tekton Pipeline to deploy a mobile app back end to OpenShift 4
Building secure, private cloud applications is more important than ever. The credit card example application we built serves to:
- Share a working integration of the latest features of OpenShift 4
- Explore security concepts of public cloud secuirty and approaches for creating cloud-native applications
