If you’ve been in the mainframe ecosystem for any time at all, you’ll know that the mainframe has long been associated with stability and staying power. But today’s conversation increasingly centers on the evolution of the next-gen mainframe, and how it fits into modern enterprise architecture.

This week’s quiz looks at how enterprises are actually approaching workload placement in the current landscape (as evidenced by recent industry surveys and reports). The questions explore where the mainframe continues to anchor critical operations, and where hybrid strategies are reshaping the picture. Whether you work hands-on with IBM Z or simply keep an eye on enterprise computing trends, this is a chance to test how closely you’ve been following the next chapter of the platform’s transformation.

1. In a hybrid IT strategy, what is the primary goal of workload placement?

 
 
 
 

2. Which type of workload is most commonly retained on mainframes in hybrid environments?

 
 
 
 

3. According to recent industry surveys, what is one of the main reasons organizations keep core workloads on the mainframe?

 
 
 
 

4. In hybrid architectures, what role does the cloud most often play alongside the mainframe?

 
 
 
 

5. Which technology most commonly enables mainframe data to be used by cloud-native applications?

 
 
 
 

6. When organizations evaluate workload placement, which factor is typically MOST important?

 
 
 
 

7. Which hybrid pattern is most commonly recommended by analysts?

 
 
 
 

8. Which of the following best describes Linux on IBM Z in a hybrid strategy?

 
 
 
 

9. In hybrid workload planning, which metric is most commonly used to evaluate the long-term economic efficiency of running steady transaction workloads on the mainframe?

 
 
 
 

10. From a hybrid placement perspective, which workload characteristic most strongly favors deployment in elastic cloud environments rather than on the mainframe?

    You scored 9 / 10

    Well, I am not so far away from actually working on the Mainframe every day that I don’t understand the benefits and goals for hybrid environments. Since our software helps customers, who we refer to as “Mainframe Mailers,” eliminate MSU fees by running on a zIIP, I should not have missed the question related to MSUs! 🙁

    I gave it my best shot.

      I suppose after 40 years on the platform I should know this stuff!

    I learned long ago, and shortly after learning to use CDC and DEC, that the IBM mainframe was going to be a transformative critical business tool. Even during the days of the ‘mainframe is dead’, I was quite certain most had it wrong.

    Eliminated alternatives in 10 and placed a bet on “bursty…..”.

    10 out of 10 smashed it 🙂

    There are somethings the mainframe just can’t be beaten for and others where cloud and the ability to scale up or down simply makes sense.

    Thanks for another great quiz Planet Mainframe!
