ISG To Publish Study On Modernizing Mainframes In The Enterprise Environment

ISG Provider Lens report will look at ways providers are helping enterprises move mainframe applications to the cloud

Information Services Group (ISG) a leading global technology research and advisory firm, has launched a research study examining service providers that help enterprise customers modernize their traditional mainframe-based IT environments and move applications to the cloud.

The study results will be published in a comprehensive ISG Provider Lens™ report, called Mainframes ­– Services and Solutions, scheduled to be released in April. The report will cover several mainframe-related services, including mainframe modernization, mainframe application modernization and mainframes as a service.

The report also looks at ways enterprises that prefer to keep legacy applications on mainframe platforms can introduce agile methods, DevOps, application programming interfaces and microservices to improve agility and integrate mainframes with private and public clouds.

Enterprise buyers will be able to use information from the report 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.

The new report will examine how service providers are helping enterprises move to cloud environments and align their mainframe applications with their digital business strategies, said Jan Erik Aase, partner and global leader, ISG Provider Lens Research. “Service providers leverage high-performance hardware and software tools for continuous modernization, enabling mainframe applications to integrate with new technologies and computing platforms,” he said.

ISG has distributed surveys to more than 65 mainframe technology and service providers. Working in collaboration with ISG’s global advisors, the research team will produce five quadrants representing the services and products the typical enterprise client is buying in the mainframe space, based on ISG’s experience working with its clients. The five quadrants are:

• Mainframe Modernization, examining providers that offer legacy application modernization and introduce code repositories such as GitHub or equivalents, DevOps integration, testing automation and security testing. Modernization retains the original programing language, such as COBOL, adding architecture optimization and documentation to enable agility.

• Mainframe Application Modernization and Transformation, covering providers of application development and maintenance services with newer application modernization methodologies to assess and rewrite legacy programming language applications written with COBOL, RPG, Fortran, PL/1, Natural and others that typically run on mainframes. The main target programming languages may include Java, .Net, C# and others, enabling the same logic and business rules to run on any platform, including the public cloud.

• Mainframes as a Service (MFaaS), examining infrastructure service providers that offer shared IBM Z mainframes under a pay-per-use contract model. Services include facilities, hardware, connectivity, mainframe network management, licensing, operating system and subsystems, tools, and all maintenance services that are required to keep mainframe workloads running per the expected performance established upfront.

• Mainframe Operations, assessing traditional outsourcing providers with extensive experience in offering mainframe services. Typical participants employ experienced practitioners to cover legacy mainframe technologies and the most recent mainframe releases. Mainframe operations service providers offer skilled teams to keep clients’ mainframes running. These services include job scheduling, performance optimization, CICS©, batch, backup, restore, system upgrades, security patches and other typical mainframe operations.

• Mainframe Application Modernization Software, examining providers of software and toolsets that enable legacy application assessments and application conversion, including replatforming, rehosting, refactoring, rewriting or reengineering. Mainframe modernization software includes reverse engineering, business logic mapping, business rules extraction, code review and inspection, documentation, emulators, compilers, frameworks and application development tools that can accelerate code modernization and application modernization.

The report will examine mainframe products and services available in the U.S., Canada and Europe. ISG analysts Pedro L. Bicudo Maschio and Oliver Nickels will serve as authors.

A list of identified providers and vendors and further details on the study are available in this digital brochure. Companies not listed as mainframe service providers can contact ISG and ask to be included in the study.
