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.

Course Overview
Hi, everyone. My name is Dave Nicolette, and welcome to my course, Mainframe Development: The Big Picture. I'm an independent software development consultant. I've been working with computers since 1977, including mainframes and other systems. This course is an overview of the mainframe platform and its place in the world. Did you know that despite being declared dead, mainframes are involved in more than 80% of business transactions worldwide or that a single mainframe can function as a complete cloud infrastructure. That's not bad for a cold, dead thing. Some of the major topics we will cover include the history and evolution of the mainframe platform, the hardware and software architecture, the operating systems it supports, and the practical applications and future direction of the system, including what kinds of job opportunities you might find with mainframe technology. By the end of this course, you'll know what accounts for the mainframe's longevity, IBM's plans for its future, and how your career could include working on a mainframe. Before beginning the course, you should be familiar with software development and computer systems in general. From here, you should be comfortable diving into mainframe technology with courses like Murach's Mainframe COBOL by Tom Taulli and TSO/ISPF: Getting Started, by George _____. I hope you'll join me on this journey to learn mainframe technology with the Mainframe Development: Big Picture, course at Pluralsight.
