Why EX288

The OpenShift Developer Certification for Cloud-Native Careers

OpenShift is the enterprise platform developers deploy on at banks, telcos, and cloud-native companies. EX288 is the performance-based proof that you can deliver applications on it — from S2I to Tekton pipelines.

Developers Deploy on OpenShift

Every enterprise using OpenShift needs developers who can build, deploy, and troubleshoot applications on the platform. EX288 proves you can.

Live Performance-Based Exam

EX288 is a hands-on exam — you build and deploy real applications using S2I, Helm, and Tekton on a live OpenShift cluster, not multiple choice.

Strong Demand from DevOps and SRE Teams

Cloud-native developers with OpenShift skills are in demand across telcos, banks, and SaaS companies for DevOps and SRE roles.

Complete 10-Domain Coverage

Our curriculum covers every EX288 objective — from OCP basics and S2I to Helm, image streams, Tekton CI/CD, and Operator-deployed apps.

Live OpenShift 4.x Developer Labs

Practise on a real OpenShift 4.14 developer environment — every module includes hands-on labs aligned to exam objectives.
