Evaluate the Market. Discover Opportunities. Shape Your Legacy Strategy.

The 2025 Gartner® Market Guide for Mainframe and Legacy System Cloud and Hosting Providers we believe is an essential reading for IT and infrastructure leaders navigating the complex shift from legacy architectures to modern, scalable cloud environments.

Inside the report, Gartner outlines key use cases, emerging trends, and the capabilities organizations should demand when selecting cloud or hosting providers to support mainframe and non-x86 platforms.

Our key takeaways:

  • Market dynamics, including the decline in mainframe hardware spend and the rise of modernization initiatives
  • The four strategic use cases driving legacy hosting demand:
    Public cloud proximity, small footprint optimization, read-only environments, and data center divestment
  • Comparative insight into hosting vs. cloud delivery models
  • A framework for evaluating vendors based on platform scalability, SLA strength, security, and cost-efficiency
  • A list of 14 Representative Vendors, including Comarch Group

Why It Matters

Mainframes and legacy systems remain foundational to industries like banking, manufacturing, and government. But evolving business needs and talent gaps are accelerating the move to hosted or cloud-based alternatives.

This Gartner report can help decision-makers:

  • Understand when and why to consider offloading legacy systems
  • Build a business case for modernization, grounded in objective analysis
  • Identify which vendors best align with your operational, technical, and financial requirements
