Mainframe modernization

Deloitte’s mainframe modernization services align to your business strategy to future proof your organization while maximizing ROI

The IT landscape is rapidly evolving, but mainframe technology can limit the ability to take advantage of new technologies such as Generative AI. In addition, many organizations dependent on mainframe technology face limited flexibility to meet evolving business demands due to a shrinking talent pool and rising operational costs. Deloitte’s mainframe modernization services can help you accelerate your mainframe modernization and provide your organization with the agility and flexibility you need to achieve your strategic goals.

Why mainframe modernization, why now?

Discover the power of a comprehensive cloud migration strategy for innovation and agility.

Mainframe modernization can be challenging

As the cost of operating mainframes increases, harnessing the value of cloud becomes table stakes, and Generative AI can transform opportunities to innovate, the race to accelerate modernization—especially of mainframe applications—is on.

But many organizations face steep challenges, particularly in answering strategic and tactical questions such as where to start to meet critical business needs most effectively, and how to choose appropriate mainframe modernization strategies to align investments with business priorities.

Our modernization services—delivering flexibility and choice

To help you meet your challenges, we offer three approaches to modernization. These approaches enable us to tailor our services based on your strategy and provide you with maximum flexibility and choice in how you achieve your goals. Each approach begins with an assessment of your current environment. After the assessment, you can choose from one, or all, of our three approaches in the order than makes sense for your business.

Our approach includes:

Innovating your most strategic business capabilities utilizing the latest technologies.

${column2-large-text}

Prioritizing getting off the mainframe as quickly as possible, while minimizing risk and business disruption.

${column3-large-text}

Accelerating the path to commercial off-the-shelf software or software-as-a-service.

We also have products to help streamline your modernization journey. Our TruNorth product provides a cockpit view of all the relevant assessment data to help you develop a plan for mainframe modernization. Our innoWake product helps simplify your modernization efforts by employing a fully automated migration process to convert legacy code and migrate it to cloud.

Assessment

At the outset of each modernization engagement, we assess your environment. Through this comprehensive assessment process, we deliver comprehensive insights into your mainframe environment, including dependencies across applications and data and the business capabilities they enable.

Bottoms-up technical-focus

We help you discover the risk of your “unknown unknowns.” Our thorough technical assessment, using our TruNorth, examines your entire mainframe ecosystem to unravel technical complexities, dependencies, code quality, and business rules.

Top-down functional focused assessment

We help you baseline business capabilities with sector-standard blueprints. These blueprints expedite our assessment by providing a baseline of industry leading practices and expected capabilities to benchmark against your capabilities.

“Meet in the Middle” approach

We connect the bottoms-up assessment performed by our engineers experienced in mainframe modernization with the top-down assessment, validated by our sector subject-matter specialists, to create a detailed understanding of the relationships between your technology components and the business capabilities they support.

Modernization approaches

Once your assessment is complete and we’ve worked with you to analyze the results, you can choose to start your modernization efforts with any of the approaches listed below, and you can deploy any or all of the approaches in your modernization journey.

Approach one: Innovate your most strategic business capabilities utilizing the latest technology

Our TruNorth suite plays a critical role in this approach. TruNorth helps visualize existing relationships across tables, modules, and business domains, and it identifies the interdependencies. With these insights, we can help you determine the decomposition effort and the impact of “cutting” data from your monolithic applications to move it to cloud. We have a similar capability to visualize code dependencies for “cutting” the monolith. Through this analysis, we can define bounded contexts, accelerating modernization to move from existing calls to microservices.

Key considerations for this approach include:

  • Accelerated development: With this approach you can prioritize modernization of your most strategic business capabilities first, moving them off the mainframe, to help you maximize your technical innovation choices to drive optimal competitive advantage.
  • Complex interim integrations to mainframe (coexistence): This is a progressive approach, modernizing “pieces” of your mainframe infrastructure and creating a state of “coexistence” with capabilities both on and off the mainframe that will require integration points to be developed and maintained until all capabilities have been moved off the mainframe.
