Enterprise Mainframe Spending Expected to Increase Alongside Public Cloud Adoption, ISG Study Finds

Rhea-AI Summary

According to a new ISG Market Lens™ study, companies using mainframes expect to increase their mainframe spending while also increasing public cloud adoption. The survey of 200 executives in the Americas and Europe found that:

- 33% expect to upgrade existing mainframe processors or storage
- 40% expect to increase capacity for traditional mainframes
- 1 in 6 expect to purchase a new mainframe over the next three years

Key findings include:
- Mainframe compute and storage requirements are expected to rise, particularly in MFaaS
- 60% of enterprises have migrated some applications to the cloud in the past 3 years
- 40% have migrated to MFaaS
- Top priorities are cost optimization, retiring legacy systems, adding AI capabilities, and information security
- Nearly a third face challenges in accessing mainframe skills and talent

Positive

Insights

Technology Analyst

The study reveals a complex landscape for enterprise IT, with mainframes maintaining relevance alongside cloud adoption. Key findings include:

• 33% of large enterprises plan to upgrade mainframe processors or storage
• 40% expect to increase traditional mainframe capacity
• 1 in 6 anticipate purchasing a new mainframe in the next three years

This trend contradicts the notion that cloud will completely replace mainframes. Instead, we're seeing a strategic balance between mainframe, Mainframe as a Service (MFaaS) and public cloud. The increase in mainframe investment is driven by several factors:

• Inability to decommission legacy infrastructure
• Conflicting demands like AI adoption and data security
• Rising application storage and compute needs
• Cost optimization pressures

For investors, this suggests potential opportunities in companies providing mainframe services, MFaaS solutions and mainframe modernization services. The ongoing demand for these technologies could benefit firms like IBM, Kyndryl and other mainframe-focused service providers.

IT Infrastructure Specialist

The study highlights a significant shift in enterprise IT strategies, with implications for both mainframe and cloud sectors:

• 60% of enterprises have migrated some applications to the cloud in the past 3 years
• 40% have moved to MFaaS

MFaaS is emerging as a compelling middle ground, offering cloud-like flexibility with fewer migration and security challenges. This trend addresses several critical issues:

• Cost optimization
• Mainframe talent shortage
• Need for AI capabilities
• Information security concerns

Notably, only security is perceived as performing well on current mainframe or MFaaS systems. This presents an opportunity for vendors to improve offerings in cost reduction, AI integration and legacy application retirement. For investors, companies specializing in MFaaS solutions and mainframe modernization services could see increased demand. Additionally, firms addressing the mainframe skills gap through training or automation tools may find a growing market.

Survey of global decision-makers finds conflicting enterprise demands are keeping organizations on mainframes

STAMFORD, Conn.--(BUSINESS WIRE)-- Companies that use mainframes in their current IT operations expect to increase their mainframe spending even as they increase their adoption of public cloud, according to new survey research from leading global technology research and advisory firm Information Services Group (ISG) (Nasdaq: III).

The new ISG Market Lens™ Mainframe and Mainframe as a Service (MFaaS) Study finds one-third of large enterprises expect to upgrade existing mainframe processors or storage, 40 percent expect to increase capacity for traditional mainframes, and one in six expect to purchase a new mainframe over the next three years.

“Mainframes remain important in large enterprises, as organizations strategically balance between mainframe, MFaaS offerings and public cloud,” said Alex Bakker, ISG Distinguished Analyst and co-author of the study. “Though public cloud adoption continues to grow, it will not totally eclipse mainframes in enterprise IT. In fact, mainframe compute and storage requirements are expected to rise, particularly in the form of MFaaS.”

The ISG study was conducted in July 2024 and covered 200 executives in the Americas and Europe with decision-making responsibility for mainframe and MFaaS strategy. The results show enterprises with the largest current IT workloads expect to see the greatest increase in need across all platforms, while those with a high proportion of traditional mainframe expect to accelerate transition to MFaaS to keep pace with their needs.

“Mainframe demand is being fueled by enterprises’ inability to decommission their legacy infrastructure, often due to conflicting enterprise demands such as the adoption of AI, while others are prioritizing data security and resiliency,” said Michael Dornan, principal analyst and co-author of the study. “At the same time, application storage and compute demands are on the rise and IT departments face pressure to optimize costs.”

Over the past three years, nearly 60 percent of enterprises have migrated some applications to the cloud, and over 40 percent have migrated to MFaaS, the study found. MFaaS is often viewed as a lower-cost solution that offers the flexibility and interoperability associated with public cloud with fewer migration and security challenges. It’s also a potential solution to mainframe talent challenges as those with traditional skills retire from the talent pool.

Top enterprise mainframe priorities are cost optimization, retiring legacy applications and infrastructure, adding AI capabilities and information security, but of these, the study found only security is rated as performing well. Fifty-four percent of respondents say information security on their current mainframe or MFaaS is performing better than peer organizations, while cost reduction (rated better than peer companies by 36 percent of respondents), AI (29 percent) and legacy retirement (31 percent) are all struggling to keep pace.

In addition, nearly a third of enterprises say accessing mainframe skills and talent is a challenge, as early retirement reduces staff availability and new employees are less likely to know legacy programming languages. Nearly all respondents were using managed service providers to support mainframe modernization and operations or MFaaS services.

“The competing priorities and challenges surrounding mainframes will drive enterprise demand for mainframe modernization services as companies turn to providers to help them get the full value from existing investments,” Dornan said. “Providers will be expected to impact the bottom line through cost optimization and deliver the benefits of integration and interoperability with other systems and services, including cloud.”
