By Deployment

On-premise deployment holds the dominant share, accounting for over 70% of the segment as enterprises prioritize full control over data, compliance, and security. This model remains essential for financial services, public sector agencies, and telecom operators handling sensitive, high-volume transactions. Hybrid deployment is growing quickly as organizations integrate mainframes with cloud platforms to improve scalability and modernization. Cloud-only deployment represents the smallest sub-segment but continues to expand as enterprises adopt flexible consumption models and shift selected workloads off-site.

Key Growth Drivers

1. Rising Demand for High-Volume Transaction Processing

The mainframe market continues to expand as enterprises increasingly rely on platforms that support high-volume, low-latency transaction processing. Banking, insurance, retail, and government agencies handle millions of daily transactions that require unmatched reliability, throughput, and uptime. Mainframes deliver consistent performance with sub-second response rates and near-zero downtime, enabling mission-critical operations. The growth of digital banking, online payments, and real-time fraud detection further fuels adoption, as organizations seek systems capable of processing massive workloads securely while maintaining strict regulatory and operational requirements.

• For instance, IBM z17, announced in 2025, runs on the new Telum II processor, which supports more than 450 billion AI inferencing operations per day with 1‑millisecond response time.

2. Expansion of Hybrid IT and Modernization Initiatives

Hybrid IT adoption is accelerating mainframe demand as enterprises integrate legacy core systems with cloud-native environments. Organizations are modernizing application architectures through APIs, containerization, and DevOps pipelines to improve agility without disrupting existing workloads. Mainframe-as-a-Service offerings allow businesses to scale compute capacity on demand and reduce operational costs. These modernization strategies help enterprises unlock additional value from long-standing mainframe investments, enabling seamless interoperability with public cloud platforms while preserving the performance, auditability, and security benefits inherent to mainframe infrastructure.

• For instance, TCS, this AI‑powered solution can reduce modernization costs by over 70% and deliver application modernization results twice as fast as traditional manual conversion approaches.

3. Increasing Focus on Advanced Security and Compliance

Growing cybersecurity risks and stricter compliance mandates are strengthening the role of mainframes in enterprise IT strategies. Mainframes provide built-in hardware encryption, secure multi-tenancy, centralized governance, and automated auditing capabilities that meet regulatory standards across sectors such as BFSI, healthcare, and government. Their architecture minimizes exposure to external threats and unauthorized access, offering a resilient environment for sensitive data and high-stakes operations. As threat landscapes expand and data protection regulations intensify globally, organizations view mainframes as essential platforms for safeguarding critical digital assets.

Key Trends & Opportunities

1. Integration of AI, Automation, and AIOps

AI-driven automation is reshaping mainframe operations as enterprises deploy AIOps for predictive maintenance, anomaly detection, workload optimization, and intelligent resource allocation. These capabilities reduce manual intervention, enhance availability, and improve operational efficiency. Vendors increasingly integrate on-chip AI accelerators and machine-learning-based tools to streamline performance tuning and boost real-time processing. The opportunity lies in leveraging mainframes as centralized analytics hubs that handle large-scale datasets, enabling enterprises to embed AI into mission-critical workflows without compromising speed, security, or reliability.

• For instance, DXC also claims to complete 47,000 workload migrations to the cloud annually, leveraging AI and automation to accelerate and de-risk transitions from legacy mainframe environments.

2. Growing Adoption of Mainframe-as-a-Service (MFaaS)

MFaaS is emerging as a strategic opportunity as organizations seek to reduce capital expenditure while maintaining mainframe capabilities. Cloud-based consumption models allow enterprises to access scalable compute power, automated updates, and managed services without investing in hardware ownership. This shift supports modernization, accelerates deployment, and simplifies maintenance for organizations with limited in-house expertise. MFaaS providers also offer advanced monitoring, security, and system integration services, making the model attractive for sectors with fluctuating workloads or regulatory-driven compute demands.

• For instance, HCL manages more than 710,000 MIPS (Million Instructions Per Second) across its global mainframe delivery footprint.

3. API-Driven Modernization and Open-Source Integration

API-driven modernization is enabling mainframes to integrate seamlessly with open-source tools, microservices, and cloud-native applications. Enterprises are increasingly adopting RESTful APIs, Linux distributions, and open frameworks to modernize legacy applications while retaining core processing capabilities. This trend opens opportunities for hybrid application development, faster innovation cycles, and improved data accessibility. Companies can extend traditional workloads into digital ecosystems without rewriting entire platforms, reducing modernization risks and costs while enhancing operational flexibility.

Key Challenges

1. Shortage of Mainframe Skills and Aging Workforce

A significant challenge facing the mainframe market is the shrinking pool of skilled professionals. Many experienced COBOL, z/OS, and mainframe systems engineers are nearing retirement, while younger IT professionals gravitate toward cloud-native and open-source technologies. This talent gap complicates maintenance, modernization, and innovation efforts. Organizations struggle to recruit and train new talent capable of managing both legacy applications and modern integration frameworks, increasing operational risks and slowing digital transformation initiatives reliant on mainframe infrastructure.

2. High Modernization Costs and Integration Complexity

Despite their advantages, mainframes often require substantial investment for upgrades, application modernization, and integration with cloud ecosystems. Migrating legacy code, rearchitecting systems, and aligning mainframe workloads with digital platforms can be time-consuming and costly. Complexity increases when enterprises manage heterogeneous environments or depend on decades-old custom applications. Additionally, modernization efforts may disrupt mission-critical operations if not managed carefully. These challenges create barriers for organizations with limited budgets or constrained technical resources, slowing the pace of transformation.
