The CP4S tutorials¶

Audience: Architects, Application developers, Administrators

Overview¶

In this topic we're going to:

• Introduce you to the CP4S tutorials
• Outline the structure of the tutorials

By the end of this topic you'll understand the CP4S tutorials, and how they can help you design and build cloud native CP4S systems.

Introduction¶

The purpose of the CP4S tutorials is to teach architects, developers and operations staff how to implement a production-ready CP4S deployment on the OpenShift Container Platform. It makes extensive use of the IBM Cloud Pak for Integration (CP4S) and other cloud native technologies such as Tekton, Kustomize, ArgoCD, Prometheus, Grafana and Kibana.

Cloud native systems are loosely coupled, making them resilient, manageable, and observable. A cloud native systems brings robust DevOps automation which allows CP4S developers, administrators and architects to make high quality changes with predictability and minimal toil as frequently as their organization requires.

Using worked examples, you will build and run a modern CP4S deployment according to cloud native principles, gaining hands-on experience of these technologies and their benefits.

The tutorial is structured as a set of tutorials and it is recommended that you follow them in order. Earlier tutorials are foundational, whereas later ones such as high availability and disaster recovery cover advanced features. If you already have a good working knowledge of CP4S and OpenShift, these more advanced topics can be attempted stand-alone. There is an intuitive table of contents. Next and Previous links at the bottom of each page to help you navigate.

The tutorial is intended as a complement to CP4S product documentation; where relevant the tutorial will refer to it and other documents.

Tutorial structure¶

This tutorial is divided into chapters that help you build, step-by-step, a set of working CP4S deployments, based on a cloud native approach. Each chapter comprises topics which you should complete in order to gain a full understanding. The tutorial starts with a simple CP4S application and queue manager. It progresses to CP4S uniform cluster, CP4S NativeHA and multiple availability zone and region configurations.

The tutorial is structured to match the development and operations lifecycle:

• Install and upgrade
• Build and test
• Deployment
• Promotion
• Security
• Monitoring
• Scalability
• Performance
• High Availability
• Disaster recovery
• CPU, memory, network utilization
• Server consolidation

See how the table of contents on the left of this tutorial is arranged to match this lifecycle.

Architecture decisions¶

Throughout the tutorial you'll see alternative implementation choices:

The inline text gives a summary of the architecture decision used to make the technical choice. The link provides a full explanation of the architecture decision.

All architecture decisions are described in the Architecture decisions registry.
