The banking and financial services sector is undergoing a gradual shift towards more platform-oriented IT environments. As part of this transition, established platforms such as Red Hat Enterprise Linux (RHEL) and OpenShift have assumed an increasingly important role as the foundation for mission-critical IT. Several parallel requirements are driving this development, often reinforcing one another while at times creating competing priorities. On the one hand, organisations face growing demands for faster digital innovation, new services and AI-driven solutions. On the other, expectations around stability, security and regulatory compliance continue to increase.
This balancing act is not new to the industry. However, as systems have become more distributed, maintaining that balance has become increasingly complex. As a result, platforms based on Linux and container technology have taken on a central role in modern IT environments.
In this article, we take a closer look at how RHEL and OpenShift are used across the banking and financial services sector and the role they play in supporting modern, business-critical IT operations.
Banking and Financial Services – A Unique IT Landscape
From an IT perspective, the banking and financial services sector is unique not only because of specific technical requirements, but because of the combination of rapid change, regulatory oversight and an exceptionally low tolerance for service disruption. IT environments must simultaneously support continuous transformation and a very high degree of operational stability.
As a result, architecture cannot be optimised for a single objective. It must support both change and predictability, often within the same platform and sometimes within the same application landscape.
Many organisations are also operating in environments where legacy systems must coexist with new initiatives involving hybrid cloud and AI. This adds a further layer of complexity and places additional demands on the underlying platform.
Red Hat Enterprise Linux (RHEL) as a Stable Foundation
Red Hat Enterprise Linux, commonly referred to as RHEL, is an enterprise Linux platform designed for organisations with demanding requirements for stability, security and predictable operations over time.
In environments where availability and operational resilience are critical, predictability becomes a key characteristic. This applies both to how systems behave over time and to the way updates, security patches and life-cycle management are handled. Unlike consumer-focused operating systems, RHEL is designed for environments where systems must operate consistently over extended periods, where security updates need to be managed in a controlled manner, and where infrastructure changes must remain predictable.
This is one of the reasons Linux platforms have established such a strong position within mission-critical IT. The combination of flexibility, security and control makes them particularly well suited to environments where availability and regulatory compliance are essential.
Within banking and financial services, this has made RHEL a key component of many organisations’ core IT infrastructure, providing a stable foundation on which to build.
OpenShift – Modernising the Application Platform
OpenShift is Red Hat’s Kubernetes-based platform for building, running and managing containerised applications across large-scale IT environments.
In practice, it provides a more standardised and automated approach to how applications are developed, deployed and operated, regardless of whether the underlying infrastructure resides in a private data centre, in the cloud or within a hybrid environment.
Within banking and financial services, OpenShift is often used as a means of modernising application environments without undertaking large-scale and high-risk transformations of existing systems. This is particularly relevant as legacy systems must coexist with new digital services while requirements for security, governance and control remain unchanged.
Container platforms have become increasingly important in large IT environments in recent years, primarily because they simplify the creation of consistent environments for both development and operations. This reduces dependencies between systems and makes it easier to scale, update and standardise applications over time.
Today, Iver’s Managed OpenShift service forms the foundation for several business- and society-critical systems across both healthcare and the banking and financial services sectors.
Technology Is Rarely the Greatest Challenge
In discussions with organisations across the banking and financial services sector, a common challenge frequently emerges: the technology itself is rarely the primary issue. The real challenge lies in ensuring that technology can be operated effectively and sustainably over time.
Organisations need architectures that support long-term operations while remaining flexible enough to accommodate change. It is equally important to ensure that security and regulatory requirements are not treated as separate concerns, but are integrated into the platform itself from the outset.
In many cases, it is the interaction between these requirements that creates complexity rather than any individual technical component. Designing platforms that successfully balance innovation, governance and operational stability is often the most demanding aspect of the journey.
OpenShift for AI in Banking and Financial Services
AI has rapidly become a key part of the technology agenda and is also reshaping the requirements placed on underlying platforms.
Issues relating to data management, traceability and governance have become increasingly important, particularly in regulated environments where it is not sufficient for technology simply to function. Organisations must also be able to explain, document and monitor how outcomes are generated.
As a result, AI often becomes as much a question of platform and governance as it is of models and algorithms. AI cannot be treated as a separate initiative; it must be considered an integral part of the wider platform strategy.
In this context, OpenShift serves as an enabling platform, combining isolation, scalability and control within a unified environment. By providing a consistent platform for application workloads, data services and AI initiatives, organisations are better positioned to innovate while maintaining compliance and operational oversight.

The Shift Towards Platform-Oriented IT Environments
The direction of travel within banking and financial services is clearly towards more platform-oriented IT environments. Rather than maintaining separate solutions for different requirements, organisations increasingly need integrated platforms where infrastructure, applications, security and operations are managed as part of a cohesive whole.
Several factors are driving this development. On the one hand, organisations are seeking better conditions for innovation and faster development cycles. On the other, they need to manage security, governance and regulatory requirements more consistently across the entire IT landscape.
As IT environments become more distributed, the need for standardisation also increases. This applies not only to technology choices, but also to the way environments are built, monitored and managed over time.
For many organisations, this level of standardisation is becoming a prerequisite for combining innovation with stable operations. Without a common platform approach, it becomes increasingly difficult to maintain efficiency, control and resilience as complexity grows.
At the same time, this evolution is influencing how IT organisations are structured. The focus is gradually shifting away from individual systems and isolated infrastructure towards the performance of the entire platform as an integrated environment. Consequently, areas such as automation, security and operations can no longer be managed separately. Instead, they must be built into the platform from the very beginning.
This shift reflects a broader understanding that technology platforms are no longer simply infrastructure. They have become strategic enablers of business agility, resilience and long-term competitiveness.
