How Kaltura Accelerates CI/CD Using AWS CodeBuild-hosted Runners

This article describes how Kaltura migrated its CI/CD infrastructure from self-managed Amazon EKS runners to AWS CodeBuild-hosted runners for GitHub Actions, achieving significant operational and cost improvements.

• Reduced DevOps operational overhead by 90% and infrastructure costs by 60%
• Decreased build queue times by 66% through webhook-based architecture instead of polling
• Eliminated manual configuration requirements with auto-discovery and self-service capabilities
• Maintains enterprise security with VPC isolation, IAM fine-grained access, and private network access
• Supports 1,300+ daily builds across 1,000+ repositories and 100+ workflow types
• Simplified Docker builds with native CodeBuild support, eliminating Docker-in-Docker complexity
• Minimal migration effort requiring only single-line workflow changes to runs-on label

Kaltura's migration demonstrates how managed AWS services can replace complex self-hosted infrastructure while improving performance, reducing costs, and maintaining enterprise-grade security requirements.
