ISG to Publish Reports on Mainframe Services and Solutions

Upcoming ISG Provider Lens™ reports will evaluate providers helping enterprises and U.S. public sector agencies modernize mainframe applications and operations

Information Services Group (ISG) (Nasdaq: III), a leading global technology research and advisory firm, has launched a research study examining service providers that enable enterprises and U.S. public sector organizations to transform legacy mainframe environments to meet current needs.

The study results on enterprise mainframe products and services will be published in a comprehensive ISG Provider Lens™ report called Mainframes — Services and Solutions 2024, scheduled to be released in April 2024. The report will cover companies that modernize mainframe applications for the cloud, offer mainframe outsourcing and mainframe-as-a-service (MFaaS), as well as automation tool vendors.

At the same time, ISG will publish the U.S. Public Sector Mainframes — Services and Solutions 2024 report, covering providers with experience in delivering mainframe modernization to state, local, municipal and educational entities in the U.S.

Buyers at enterprises and public agencies will be able to use information from the reports to evaluate their current vendor relationships, potential new engagements and available offerings, while ISG advisors use the information to recommend providers to the firm’s buy-side clients.

Businesses and public service organizations are turning to mainframe modernization to reduce technical debt, enable artificial intelligence (AI), provide better business analytics, enhance compliance, improve resilience and meet carbon-neutral commitments. Generative AI (GenAI) contributes to enhancing automated tools to transform legacy applications for the cloud.

"Mainframe modernization propels businesses forward, merging legacy environments with future-ready cloud innovations," said Jan Erik Aase, partner and global leader, ISG Provider Lens Research. "Enterprises and public sector agencies are leaning on service providers to harness the cloud's resilience, optimize costs and tap into the transformative potential of GenAI."

For the enterprise mainframe services and solutions study, ISG has distributed surveys to more than 130 mainframe product and service providers. Working in collaboration with ISG’s global advisors, the research team will produce five quadrants representing the mainframe services and solutions the typical enterprise is buying, based on ISG’s experience working with its clients. The five quadrants are:

  • Mainframe Optimization Services, evaluating providers of mainframe application modernization that retains the original programming language (such as COBOL) and adds optimization and documentation to enable agility.
  • Application Modernization Services, covering service providers that use advanced application modernization methodologies to rewrite applications written in legacy programming language applications (such as COBOL, RPG, Fortran, PL/1 and Natural) to modern languages (including Java, .Net, C#, Python and others).
  • Mainframe as a Service (MFaaS), assessing infrastructure providers offering shared IBM mainframes on a pay-per-use basis, including all infrastructure components, along with maintenance to ensure workloads perform according to pre-established metrics.
  • Mainframe Operations, evaluating traditional outsourcing providers with experience in mainframe services, which may be delivered in the client’s data center, provider-owned data centers or colocation facilities.
  • Mainframe Application Modernization Software, covering software vendors and toolsets for assessing and converting mainframe applications. Modernization software may include automation tools for reverse engineering, business rules extraction, code review, inspection and other functions.

Geographically focused reports from the study will cover the global mainframe services and solutions market and examine products and services available in “APexCJK” – the Asia Pacific region including the ASEAN countries of Indonesia, Malaysia, Philippines, Singapore, Thailand and Vietnam, as well as Australia and New Zealand, but excluding China, Hong Kong, Japan, Korea and Taiwan – as well as Brazil, Europe, the U.S. and the U.S. Public Sector. ISG analysts Pedro L. Bicudo Maschio (Americas), Oliver Nickels (Europe) and Phil Hassey (“APexCJK”) will serve as authors of the report.

A list of identified providers and vendors and further details on the mainframe services and solutions study are available in this digital brochure.

For the U.S. public sector study, ISG has distributed surveys to more than 60 providers with experience serving U.S. public agencies. ISG will evaluate the providers in four quadrants:

  • Mainframe Modernization Services, assessing providers of legacy application modernization, retaining the original programming language (such as COBOL), and adding modern application development practices (such as DevOps) to enable agility.
  • Application Modernization Services, evaluating service providers that rewrite legacy applications using newer target languages such as Java, .Net, C# and Python to keep applications running and preserve business logic in the face of dwindling numbers of developers skilled in decades-old languages.
  • Mainframe as a Service (MFaaS), covering providers of shared IBM Z mainframes hosted in a data center operated by the provider or a partner. Clients contract for the services on a pay-per-use basis with agreed-upon standards for application performance.
  • Mainframe Operations, evaluating outsourcing providers with skilled teams to keep clients’ mainframes running. They can provide services in the client’s or the provider’s data center. Services typically include job scheduling, performance optimization, security patches and other functions.

A report will cover relevant services available in the U.S. public sector. ISG analyst Peter Crocker will serve as author of the report.

A list of identified providers and vendors and further details on the public sector study are available in this digital brochure.

Providers not listed in either brochure can contact ISG and ask to be included in the study.
