One of Belgium's largest communications companies sought a seamless application migration to Red Hat OpenShift Container Platform 4 (OCP 4), adhering to all the best practices around container security and vulnerability.

The Challenge

Migrating to a new container platform

Our client was facing significant challenges in application migration from OCP 3 to OCP 4. These included:

  • Overloaded infrastructure due to over-provisioning at the hypervisor and OpenShift layers
  • Poor planning for the capacity requirements and projections from application teams
  • Lack of skilled resources for migration
  • Unavailability of an automated solution for image availability in the enterprise registry for the developers

The Objective

Streamline migration

They sought to streamline their OpenShift clusters and a seamless migration to OCP 4.

  • Application migration from OCP3 to OCP4
  • Improve cluster performance
  • Optimized use of hardware
  • Refinement of log shipment and monitoring stack

The Solution

Seamless migration to Red Hat OCP 4

HCLTech helped them set up the container platform, improve the cluster performance and monitor the applications. Our solution:

  • Defined platform architecture and designed the container platform
  • Ensured seamless migration to OCP 4 with all the integrations in place
  • Improved cluster performance by refining the CPU request and default resource values in a limited range across clusters for better capacity usage
  • Automated the central inventory monitoring and showcased the real-time cluster usage by creating a monitoring dashboard
  • Implemented app log forward solution on OCP4 towards ELK and Splunk, including nested JSON parsing
  • Enabled the application teams for image sync, repo creation and migration activities

The Impact

Measurable time savings

Our client experienced rapid and agile migration to OCP 4.

  • Saved hours of time and effort through automating processes around node addition and OpenShift 4 cluster build using Terraform
  • Effective forecasting is achieved through real-time data consumption captured on a centralized dashboard
  • Decommissioning of OCP 3 within the stipulated timeframe
  • The logging and monitoring stack helped users analyze their logs effectively
