I am an IBM Z Student Ambassador and a rising senior at VCU (Virginia Commonwealth University) Small-Business (50 or fewer emp.) 8/22/2025 "Powerful, Reliable Platform for Enterprise-Scale Workloads" 4.5/5 What do you like best about IBM Z? What I really liked about IBM Z is that it provides an unmatched scalability for critical applications. It's strong in processing large volumes of transactions securely, which makes sense why many enterprises rely on it. What I really like is how an old technology like mainframe is able to integrate modern capabilities like APIs, AI, Cloud, and etc. without sacrificing its strengths in performance and security. Review collected by and hosted on G2.com. What do you dislike about IBM Z? I think one think I find as a struggle (not something I completely dislike), would be the learning curve. New developers might find the mainframe environment intimidating compared to modern cloud platforms. Implementation can required specialized knowledge. Also, it may be costly for small organizations to setup a mainframe environment. Review collected by and hosted on G2.com. What problems is IBM Z solving and how is that benefiting you? IBM Z is helping consolidate large-scale data processing and transactional workloads into a secure environment. It solves challenges around handling high-volume transactions with zero downtime. I would say the benefit would be that it improves efficiency, reducing risk, and supporting modernization without disrupting critical systems. IBM Z is also addressing the need for scalability, reliability, and security in financial and enterprise-grade applications. I believe that IBM Z is also helping bridge the gap between older systems and modern digital services. Review collected by and hosted on G2.com.

IBM Z & LinuxONE Brand Leader 10/12/2025 "Highly Reliable and Scalable for Critical Financial Workloads" 5/5 What do you like best about IBM Z? I really appreciate the reliability and scalability of IBM Z, as these are top concerns for any financial institution I work with. The security standards, including the latest quantum-safe security offerings, are impressive and meet the high demands of my industry. The evolution from console mode to GUI-based interactions, along with Watson x assistance, has made life easier by simplifying tasks.

IBM Z integrates well with Red Hat Linux, enhancing my operations with wide support for various software. Review collected by and hosted on G2.com. What do you dislike about IBM Z? I think the form factor of IBM Z could be improved further. While there's been some change with the introduction of rack-mounted options for business class servers, enterprise class servers still come as large units that can take up several racks. It would be beneficial if the form factor could be minimized even more. Additionally, although electricity consumption has already been reduced, making further reductions would help align with sustainability standards. Review collected by and hosted on G2.com.
