Red Hat OpenShift: Bridging the Gap Between Legacy and Modern Applications

The IT landscape is a tapestry woven from both legacy and modern applications. Legacy applications, often built on monolithic architectures, hold crucial business logic and data. Modern applications, built with containers and microservices, offer agility and scalability. But managing these disparate worlds can be a challenge. This is where Red Hat OpenShift steps in, offering a hybrid cloud application platform that seamlessly supports both legacy and containerized workloads.

What is Red Hat OpenShift?

Red Hat OpenShift is a Kubernetes-based container platform that streamlines the development, deployment, and management of containerized applications. Built on a foundation of Red Hat Enterprise Linux (RHEL), it provides a secure and reliable environment for running containerized workloads. However, OpenShift’s capabilities extend beyond just containers. It offers a robust framework for integrating legacy applications into the modern application landscape.

Supporting Legacy Applications

OpenShift offers several ways to integrate legacy applications:

  • Virtualization: Legacy applications can be virtualized and deployed as pods within OpenShift clusters. This allows them to leverage the platform’s security, networking, and scaling capabilities.
  • API Integration: OpenShift provides tools for exposing legacy application functionalities as APIs. These APIs can then be consumed by modern containerized applications, enabling a hybrid integration approach.
  • Sidecar Containers: For more fine-grained integration, sidecar containers can be deployed alongside legacy applications. These containers can handle tasks like logging, monitoring, and security, offloading them from the legacy application and improving its efficiency.

Benefits of a Hybrid Approach

By supporting both legacy and containerized workloads, OpenShift offers several key benefits:

  • Reduced Complexity: Organizations can manage their entire application portfolio from a single platform, simplifying operations and reducing tool sprawl.
  • Modernization Flexibility: Legacy applications don’t have to be ripped and replaced overnight. OpenShift allows for a gradual modernization approach, integrating legacy functionalities into new, modern applications.
  • Improved Resource Utilization: OpenShift efficiently allocates resources across both legacy and containerized workloads, leading to better utilization of hardware infrastructure.
  • Faster Time to Market: The platform’s automation capabilities streamline the development and deployment process, allowing organizations to deliver new features and applications faster.
  • Enhanced Scalability: OpenShift allows for horizontal scaling of both legacy and containerized applications, ensuring they can handle increasing workloads.

Challenges Addressed by OpenShift

The hybrid approach championed by OpenShift addresses several key challenges faced by IT teams:

  • Integration Silos: OpenShift breaks down the silos between legacy and modern development teams, fostering collaboration and innovation.
  • Security Concerns: The platform enforces security policies across the entire application stack, ensuring a consistent security posture for both legacy and containerized workloads.
  • Infrastructure Management: OpenShift simplifies infrastructure management by providing a unified platform for managing both legacy and containerized deployments.
  • Skills Gap: The platform’s automation features and developer tools reduce the reliance on specialized skills, allowing teams to focus on building great applications.


Red Hat OpenShift offers a compelling solution for organizations navigating the hybrid IT landscape. By seamlessly supporting both legacy and containerized workloads, it empowers businesses to bridge the gap between the old and the new. With its focus on security, scalability, and automation, OpenShift helps organizations deliver modern applications faster, while ensuring the continued operation of their critical legacy systems. As businesses continue to modernize their application portfolios, Red Hat OpenShift is poised to play a pivotal role in this transformation journey.
