Modernize and Optimize Your Mainframe Infrastructure with VRNexGen​

At VRNexGen, we bring a future-ready approach to infrastructure modernization, modernizing your mainframe infrastructure.

Our services are designed to help enterprises integrate advanced tools and frameworks, ensuring enhanced performance, scalability, and automation across their IT landscape. With over 20 years of expertise, we specialize in delivering tailored solutions that modernize your legacy infrastructure without compromising reliability or security.

Why Mainframe Infrastructure Modernization Matters

Legacy infrastructure can limit scalability, increase operational costs, and slow innovation. VRNeXGen helps organizations modernize IBM Z environments through automation, DevOps, cloud integration, and AI-driven operations, enabling greater agility, reliability, and performance.

Our Mainframe Infrastructure Modernization Solutions Include:

Automated Discovery and Delivery Insights (ADDI)

Leverage ADDI to gain comprehensive insights into your application landscape, helping you understand dependencies and streamline your modernization efforts.

IBM Developer for z Systems (IDz)

Boost developer productivity with IDz, a powerful integrated development environment (IDE) that modernizes and optimizes your mainframe development processes.

AI-Driven Operations (AIOps)

Empower your mainframe operations with AIOps, automating and optimizing system performance through real-time analytics and artificial intelligence, reducing downtime and improving operational efficiency.

IBM Dependency-Based Build (DBB) and DevOps Deploy

Achieve continuous integration and deployment (CI/CD) with our expert use of IBM DBB and DevOps Deploy tools, enabling faster development cycles and streamlined deployments in z/OS environments.

z/OS Development and Test Environment (zD&T)

We help you create a seamless development and testing environment by utilizing zD&T, allowing teams to test and innovate without relying on physical mainframe resources. z Development and Test Environment (zD&T) enables enterprises to create a virtualized mainframe environment on x86 hardware. It allows developers to test, develop, and innovate without relying on physical mainframe resources. By providing an accurate replica of the z/OS environment, zD&T accelerates development cycles, reduces costs, and enhances agility. With this solution, teams can experiment, test applications, and troubleshoot in a safe, isolated environment, all while maintaining alignment with mainframe performance and reliability standards.

INFRASTRUCTURE MODERNIZATION

Manage z/OS the way
modern platforms are
managed.

Mainframe infrastructure modernization brings automation, standard REST interfaces, and configuration-as-code to the mainframe — so provisioning and administration are consistent, repeatable, and integrated with the rest of your enterprise.

WHY IT MATTERS

What you gain

These benefits are driven by mainframe infrastructure modernization practices make the mainframe cheaper to run, easier to change, and consistent with how the rest of IT operates.

01

Consistency

Configuration-as-code removes environment drift and one-off manual setups, so systems behave predictably.

02

Speed & reliability

Automated provisioning and workflows cut lead times and eliminate error-prone manual steps.

03

One operating model

The mainframe is managed with the same tools and REST interfaces as the rest of the enterprise estate.
