Mastering Mainframe Modernization

By the end of this lesson, you'll have a solid understanding of the core hardware components that make up a mainframe and the role of operating systems like z/OS in the overall architecture.

By the end, you’ll have a solid understanding of how these applications support key business processes and why they continue to play a vital role in modern enterprises.

By the end of this lesson, you’ll be able to identify key performance issues, technological shortcomings, and security risks that are often encountered with legacy mainframes.

We’ll dive into the infrastructure that powers mainframe systems, focusing on the core components like networking, storage, and databases.

We’ll explore the business rationale behind mainframe modernization, specifically how companies can reduce costs through cloud integration and automation, as well as improve system agility and business responsiveness.

We’ll explore how integrating with modern technologies like cloud, mobile, and analytics can reduce downtime, improve scalability, and enhance security.

We'll explore how outdated technology impacts business growth and security and discuss the competitive disadvantage of failing to keep pace with companies that have already embraced modernization.

We’ll dive into real-world case studies to see how businesses successfully transitioned from legacy mainframe systems to modern infrastructures.

We’re going to explore one of the most widely used modernization strategies: Re-hosting.

We’re diving into one of the most important modernization strategies: Re-platforming.

The focus is one of the most complex and impactful modernization strategies—Refactoring.

We’re tackling a significant decision point in mainframe modernization—Replacing Legacy Systems.

We’ll begin constructing a clear, actionable modernization roadmap.

We move forward with creating a step-by-step migration plan that will guide you through the complex process of modernizing your mainframe systems.

We’ll explore the process of identifying potential risks, creating a mitigation plan, and developing contingencies for when things don’t go as expected.

We’ll focus on how to involve all key stakeholders—from technical teams to business leaders and vendors—throughout the modernization process.

We’ll explore the fundamental concepts of hybrid cloud architectures, specifically how they can seamlessly work with your mainframe systems.

We’re going to explore the powerful tools of APIs and microservices architectures to modernize legacy systems, particularly mainframes.

We’ll discuss how to select the right cloud platform for integrating mainframe workloads.

We’ll be diving into two critical aspects of cloud integration—security and compliance.

This lesson is all about introducing you to DevOps, specifically how it applies to mainframe environments.

We’re going to be focusing on setting up Continuous Integration and Continuous Deployment (CI/CD) pipelines for mainframes.

We’ll dive into Infrastructure as Code (IaC) and how it can transform how you manage mainframe environments.

We’ll focus on one of the core principles of DevOps: collaboration between development and operations teams.

We will explore the tools and techniques you can use to monitor modernized mainframe systems, ensuring their health and longevity in a world that demands peak performance.

We'll explore strategies for improving performance and reducing costs, especially in hybrid environments where cloud integration plays a significant role.

We will explore two key areas:

1. How to ensure your mainframe systems can scale to accommodate growing workloads.

2. Incorporating emerging technologies like AI and IoT to stay ahead of the curve.

We’ll be focusing on two critical areas: Security Management and Compliance in hybrid cloud-mainframe environments.
