Effort estimation framework for migrating OpenShift to Amazon EKS
Pratap Kumar Nanda and Pradip kumar Pandey, Amazon Web Services
Overview
Many organizations underestimate the effort required for container platform migrations. Based on observed patterns, teams often need more time and resources than initially planned, which can lead to budget overruns and extended timelines.
This guide provides a structured approach to building accurate effort estimates when migrating from Red Hat OpenShift to Amazon Elastic Kubernetes Service (EKS). We address common complexity areas that impact migration timelines, including:
Operator dependencies and custom resource definitions
Security policy translation and implementation
Container image registry migration
Network architecture and connectivity requirements
Service availability
Some AWS services aren't available in all AWS Regions. For Region availability, see AWS services by Region.
