Mainframe Myths Debunked in 5 Minutes

What do you think of when you hear the word "mainframe"? Slow? Expensive? Outdated?
In this video, Rosalind Radcliffe blows up those myths and explains how modern IBM ZSystems mainframes can accelerate your digital transformation with incredible power and speed matched with reduced energy requirements.

I'm retired now, but I have been working with Mainframes & EAMs since 1964. I've worked with IBM, RCA's, Honeywell's, Burroughs, CDC, Crays, Nixdorf's, ICL's, Univac's, Xerox, Magnuson's, and more. It has taken me to 64 countries and met many great people both in the industry and out. A Great IBM update Video.

My first 10 years in the industry were spent on big mainframes in the banking industry back in the 1980's doing transaction processing with ATM's and branch automation (and more). We had virtualization and distributed systems long before PC's even had viable networking. It's been interesting watching it go full circle over the last 40 years. A room full of rack mounted individual machines always seemed unnecessarily complex compared to a room full of a couple of mainframes.

I've learned so much about mainframes over the past year, and I'll tell you, I was very surprised! So much of global commerce and transactional processes are run on IBM mainframes, and I also didn't know that most batch jobs are run through IBM mainframes as well. This video was very informative and helpful, Rosalind. Thank you!

If more people spent just 5 minutes watching this, then the world would be a better place

Between 1997 and 2016 I used to work at Miami Dade College. The IT department had an IBM OS/390 with MVS Operating system. I was one of the 25 developers maintining applications with thousands on lines of code written in JCL, Cobol and Natural. The system also had night shift operators running scheduled jobs for the users. Online serving 8 campuses, 36, 000 students and 4, 000 employees. The system was running smothly until everything was migrated to ERP PeopleSoft working on PCs

I've done software development for 20 something years, but never mainframe. Recently, I started the Zexplore tutorial and learning more about the hardware. It's a whole other universe! The hardware throughput and flexibility of configuration is absolutely bonkers. Now It feels like commodity hardware has basically been asleep for the last decade.

Retired z/OS sysprog. What do I think of when I hear "mainframe"? Hyper-reliable. Ours had a CPU fail once. How did we know? IBM called my boss to schedule the CE to come in to replace a module, hot swap. We didn't suffer any outage because the firmware swithed in a backup CPU and restarted the failing instruction on it. No user or system software outage. Just and entry in the OS hardware log.

I am impressed with the backwards writting.

[gdevelek]

If it's not expensive, why don't you explain how z/OS license price changes proportionately with CPU count... or how much a 64GB memory upgrade costs.... Oh, and the IBM cloud charges you a mere $5.28 per hour for a small z/OS VM...

I think IBM Mainframe users should bring the customers to talk about it.. only then people in the world and the tech professionals will realize the significance of it.. Unfortunately customers can't be brought for IBM's benefit and of course their's.. today's world needs more advertisement.. New Tech guys don't check the facts.. So, along with facts, we need the real users (customers of mainframes) who should come front and talk about it.. then eventually they will find it a career opportunity and join us..

The last 3090 I was on was at a bank in the 90's. I was sold when I wrote a simple COBOL program to do some check processing and in less than 20 seconds or so, it went through 2M records. I was impressed!

Circa 2000 I worked in a data center in Nashville, TN. A coworker went to school with a guy who ran three mainframes, he got paid 200k a year for each (lots of money today, even more back then). When I asked what they were used for, thinking it was science or modeling, all three were payroll servers ;_; he told me how they processes thousands and thousands of paychecks in just a few days, for government, healthcare, etc. Not what I expected.

It's.not expensive until you see the quotes from IBM.

I used a 1410 main frame in about 1963 to run a statistical model of a large experiment, then in grad school I used a 7040 main frame to run numerical models. In about 1970 my team fixed MVS to do cloud computing using remote Aschi card readers, punches and printers. Later on, I found VM/CMS much more useful than TSO as a development system. We could submit jobs to MVS for compilation and execution. I think that the video should talk more about z-os and hardware high reliability (like say Stratus) for CICS and IMS transactions.

YoY apprx. 3-5% of the Mainframe Customers decommissioned their MF in Germany. Reason: Skill gap (Cobol, Assembler, PL/1, z/OS SysProg, Db2 and IMS skills etc.), Cost (24% MLC Increase of IBM Software and of course of the ISVs), Agility in Development. Each industry is affected (Insurance, Finance, Public, Retail, Automotive etc.). Good bye mainframe....

Very interesting perspective, but the machine is not old because we don't have any new hardware, but because of part of the environment. For example, creating a file and editing it. Most corporations run mostly legacy Applications on them. It does have pretty powerful tools, , but nobody is telling me JCL is a language with a modern syntax. It's also expensive to run and maintain. I know high-performance cloud-based solutions are expensive too. The consolidation 40:1 is just wishful thinking unless we are comparing a hierarchical problem running on a relational database on Linux vs IMS running the same problem on the mainframe, or a 15K Linux box against a million-dollar Mainframe platform.

Wish ISPF was still available for the x86 market. Loved the text editor! Started on IBM 1620/1710. Then 370, 390, and 3033. Also did DEC minis and helped invent the quad core for Intel.

[lennytheleopard]

There's still a skills shortage for classic "Z" as we are all old (or dead) but I guess this video is aimed at getting new customers on z hardware. In 1982 I was told "COBOL only has 5 years left" Nope.

[Fife_knight]

Basically it's a mainframe on steroids, occupies less space, flexibility in working in various cloud environments, conducive to applications development and maintenance

[christopherpetersen]

Not one word was false, but it's all the same song for decades with IBM. They keep fighting the wrong fights. Telum is amazing. Z is amazing, but for a huge amount of the industry, that's just noise.
