How to Combine the Performance of Mainframe with Enterprise Cloud

In this digital economy, there is a widespread misconception that mainframes should be abandoned and decommissioned. Businesses are migrating to the cloud where the pace of technological innovation outpaces business expectations. Enterprises that use mainframes for their mission-critical business applications, however, must contend with several issues, including high ownership costs, monolithic and unscalable design, license monopolies, and limited automation possibilities. Businesses today need a flexible, cost-effective technological foundation that can adapt to the changing needs of the Business 4.0TM era for the modernization of mainframes.

Mainframes are still used by businesses because of their massive transaction processing power, but they are being supplemented with flexible and current digital solutions that do not sacrifice nativity, security, modernism, latency, or compliance. Combining mainframe with enterprise cloud enables businesses to benefit from both power and flexibility.

Modernizing Mainframe Environments

The mainframe, sometimes referred to as "big iron," is demonstrating its tenacity as the demand for strong infrastructure rises. Digital businesses of today require robust data centers, storage, and networking capabilities that are difficult to obtain in the cloud. The disadvantage of just picking the cloud for its "as a service" business model is countered by mainframes' unrivaled scalability in transaction processing. Companies can significantly reduce their technical debt by upgrading their data centers. Businesses may harness the agility of the cloud to run business applications and save money, then combine it with the mainframe's transactional and processing capabilities in a combined mainframe-cloud system.

Several industries, including financial services, insurance, travel, and government, continue to rely heavily on mainframes for high-volume transaction processing. As a result of 5G and the Internet of Things, mainframes will become increasingly important for organizations that require vast volumes of data to be safely handled swiftly and at scale in real-time.

With the introduction of Linux, API, containers, and other technologies, mainframe technologies are undergoing a fundamental upgrade to keep up with quickly evolving market needs, giving them a competitive edge in the modernization process. Self-managing mainframes combine analytics, machine learning, and intelligent automation to foresee issues and discover solutions without the need for human interaction.

Enterprises are exploring a variety of techniques to upgrade their mainframe software. Some organizations have implemented DevOps and Agile processes to combine legacy mainframe systems with new cloud-based systems and procedures, with the goal of creating an enterprise-grade hybrid multi-cloud. Others are combining mainframe programs with modern engagement systems via APIs. 

Refactoring apps for a microservices architecture is another technique for optimizing the portfolio and mitigating risk. This method places the appropriate programs on the appropriate platform, boosting mainframe performance and lowering the cost of processing important workloads.

Another effective method has been to use hybrid cloud strategies that combine mainframe and cloud investments for seamless innovation, new ways of working, and skill acquisition for long-term development and success. Companies that have taken this route have been able to establish new income streams by modernizing and virtualizing data access as well as enhancing system integration.

Every business has a unique workload. Each requires a customized approach to develop its own effective modernization plan. As much as changing fundamental mission-critical programs is difficult and risky, accessing data from mission-essential applications across conventional and cloud systems is vital to success.

Optimizing a Modernization Project

Businesses are compelled to deal with the difficulties of legacy modernization and tech upgrade due to a complicated IT landscape. Mainframes may coexist with the cloud by extensively using and expanding the cloud, giving IT administrators a greater advantage in driving business goals.

Three factors are essential for successful modernization:

●The mainframe must continue to support mission-critical transactional systems.
●Workloads must be redesigned such that they can operate natively in high-performance cloud environments.
●Workloads must communicate with other distributed workloads that are executing on any infrastructure.

To establish a modernization plan, the company must consider workload parameters (such as integration, security, performance, and data volume) as well as ideal workload placement. A gradual modernization strategy that is aligned with business goals will give value through APIs and data access while modernizing legacy components, resulting in a more efficient end state.

Benefits of Synergizing Mainframe with Enterprise Cloud Computing

Infrastructure that is adaptable and elastic: The system supports several virtualized environments that are extremely secure for cloud deployments, such as the VM operating system running virtual servers, hypervisors, blade servers, and logical partitions.

Integral security: Implementing a mainframe in a cloud enterprise enables greater management with high-security transparency and offers a unified view of the whole business. Besides log management and security information and event management (SIEM) interoperability, it also offers consistency in access and identity management.

Utilize next-generation technologies like APIs, DevOps, AI, blockchain, and big data on corporate clouds to complement and complete the mainframe platform's inactive areas.

As a service for mainframes: Where new features are coupled with DevOps and containerization when possible, operational expenses and the capital-intensive mainframe upgrade cycle are minimized, and maintainability is increased.


A more agile, adaptable IT foundation is required as businesses push for digital transformation to shorten their time to market. Focusing on economic sustainability is equally important, thus, businesses must engage in programs that benefit both their employees and their customers. Cloud technologies have gained traction in the business world by providing a quicker, cleverer, and lighter technological infrastructure. Because the cloud's integration capabilities are rapidly expanding to provide organizations with agility, scalability, and flexibility to meet the dynamic demands of Business 4.0 enterprises, mainframes and the cloud may coexist on the same platform.
