Mainframe Development: Big Picture

by Dave Nicolette

This course gives an overview of the IBM Z system, general architecture, supported applications and workloads, why enterprises continue to rely on the platform, how it came to be positioned as it is, and where IBM is taking the platform in future.

What you'll learn

Ever since the late 1980s, mainframes were expected to die. But a funny thing happened on the way to the cemetery. Today, mainframes are enjoying a resurgence, and you are finding professional opportunities working on the mainframe platform. Why is that? In this course, Mainframe Development: Big Picture, you’ll learn why mainframes are still mission-critical systems in many large enterprises and government agencies. First, you'll explore the history and architecture that created the infrastructure that we see today. Next, you’ll rediscover capabilities and unique terminology of the mainframe platform. Finally, you'll learn why the platform continues to be relevant in the world of computing. When you’re finished with this course, you’ll understand how mainframes fit into the world of computing and the direction IBM sees for the platform's future.
