01Competitive Landscape

Narrative competitive analysis

- AWS vs IBM-led modernization: IBM emphasizes hybrid and on-mainframe models and incremental modernization approaches; AWS emphasizes migration of execution onto AWS and integration with AWS services. A customer's decision commonly depends on whether the organization intends to exit the mainframe platform or modernize while retaining execution on IBM Z. - AWS refactor (Blu Age) vs AWS replatform (Rocket/NTT DATA): Both approaches are offered within the AWS portfolio, but they have different cost and operational profiles. Replatform approaches can reduce immediate code changes but may preserve legacy design and attract higher runtime licensing; refactor approaches create modernized artifacts but require more conversion and testing effort. - Partner ecosystem: AWS’s approach is heavily partner-enabled; systems integrator capability and experience are frequently as important as tooling.

	AWS Mainframe Modernization	IBM watsonx Code Assistant for Z	Rocket / Micro Focus Enterprise Server (on AWS)
Suitable For	Organizations adopting AWS and seeking refactor and replatform pathways with integration into AWS ecosystem	IBM Z customers seeking AI-assisted analysis and hybrid/on-prem approaches	Organizations prioritizing runtime compatibility and rehosting of COBOL/PL/I workloads
Starting Price	Published per-core/per-runtime pricing available from the vendor; additional AWS infrastructure costs apply	Public watsonx pricing is presented at broader levels; Z-specific enterprise pricing is typically quote-based	Pricing typically provided via quotes; vendor materials emphasize as-a-service and licensed deployment models
Key Strength	Integration with AWS control plane and services; multiple modernization patterns available	Domain focus on IBM Z and hybrid deployment models; tooling aligned with on-mainframe operations	Established rehosting and runtime compatibility; familiar model for COBOL/PL/I workloads
Key Weakness	Changes to managed runtime availability for new customers; significant partner involvement; pricing complexity	Cost models and efficacy depend on codebase and program governance; still requires modernization governance	May preserve legacy architectural constraints; achieving cloud-native agility can require further refactoring
