If you are new to the topic of z/OS, Keep in mind that seventy percent of the world’s data still resides on the mainframe. If you use the z operating system in your day to day work, you know that it's a legacy system but it still does most of the processing and transactions for banks, retail, healthcare systems today. If you spend time with more modern technologies, you might not realize that the mainframe can process over 30 billion transactions per day (even more than Google) and IBM's latest mainframe hardware can process up to 146 million transactions per second. That's why it's still around and vital to the global economy. GitLab for z/OS helps the z team become more agile.
