Case Study: Employment Hero achieves faster deployments and modernization with CAST and AWS Application Modernization Lab

Employment Hero accelerates deployments by 83% with CAST

Employment Hero, a provider of HR and payroll solutions, faced challenges with a monolithic .NET payroll platform. Its 1.5+ million lines of code slowed releases and posed resilience risks. Employment Hero engaged with CAST, using CAST Highlight and CAST Imaging via the AWS Application Modernization Lab, to gain a data-driven assessment and build a clear modernization roadmap.

CAST analyzed the codebase, mapping dependencies and scoring cloud readiness. This provided a plan to decouple the monolith and prioritize modernization, shifting from IaaS toward PaaS. The results, accelerated by CAST's insights, included 83% faster deployments, 85% faster builds, and a 41% cost optimization. Engineers also saved significant weekly analysis time, reducing risk and paving the way for cloud-native services.
