What is IBM Z?

The new IBM z15 delivers performance, flexibility, availability, protection, and agility to drive digital transformation. It has changed the footprint of IBM Z with a 19” frame, that scales from one to four frames depending on the configuration, enabling significant floor space reduction.

IBM z15 has the commercial data privacy and security enforcement solution, Data Privacy Passports, that provides off-platform access revocation. Choose who accesses data, and when and at what level to revoke their access. One hundred percent of data, at-rest and in-flight, is protected with no performance trade off or application changes. With Fibre Channel Endpoint Security working with the latest DS8900F, achieve total end-to-end protection and authentication.

IBM z15 provides flexibility, portability and choice for hybrid cloud deployment. Cloud-native development simplifies life for developers as they build new applications and modernize existing ones. IBM Z supports private and public cloud via Linux, Kubernetes and industry-standard tools. With the Red Hat OpenShift support, IBM z15 adds to the user's options for cloud integration.

Instant recovery reduces the impact of planned and unplanned downtime. All systems need downtime for maintenance, and security patching.

Best suited for Linux consolidations, Oracle DBs, Blockchain Networks on a single box with extreme throughput (I tested a Ethereum Network, and it brought 4000 tx/s = that is amazing). Modernisation of old COBOL code with building new feature on in Containerised version and the same HW with HyperSockets or SMC-D is the best ultra low latency connection you can use. And with z16, now anything that uses AI models should run on IBM Z.

Companies which have to process high volume of data is best suited to use IBM z for processing. Efficiency, integrity and performance is well maintained in the Z os so for large-scale data, IBM Z os is best suited. Whereas for companies that do not have the large volume to process, Z os is not suited because cost to company for using the Z os will effect the budget of company.

In my opinion, IBM Z is extremely well suited for environments that run high levels of batch processing, online transactional processing such as CICS, interconnects to bridge multiple locations together and provide a single pane view of all locations, extremely fast, and Mainframes do not go down. In my experience, it is very uncommon for a Mainframe to just suddenly die, these boxes are not windows machines, very reliable.

IBM Z is well suited for existing Mainframe systems, where the migration cost to other architecture (money and time!) would be too high. And in that case if these systems require extending with additional functions for capacity. Meanwhile for green field deployments would makes much more sense to choose one of the other open systems, due to the much wider support personnel availability.

Its more appropriate for generative AI use cases wherein compute-intensive applications are hungry for CPU resources, and Z systems are more reliable and robust to a greater extent compared to traditional X36 or architectured Unix-based systems.

Even though Z systems cater to the needs of SMB users and businesses the penetration is not as expected in terms of price point compared to large scale Z systems.

It is recommended when someone needs a reliable system with second to none downtime and has no major crashes, it is also suited for complex and large environments where there is a need for security which IBM Z provides. Sharing large amounts of data is also very easy without any data loss.

Well suited for mission critical and business critical applications. Customers who have unpredicted spikes in workload can rely on the mainframe as it will scale and even run at 100% utilization without crashing. Highest level of security and integrity. Ideal platform for datacenter in a box. So customers who are constrained on datacenter space requirements can look at this platform .Less Appropriate for customers who can run their requirement on Windows PCs and do not require high qualities of service of high security, reliability and availability

Most of the time, server utilization is reliable and stable during peak times. Truly amazing, this product offers a lot and gets it done in no time without any confusion.It is reliable, too accurate and the performance is top-notch. It seems to be competitive in all virtual energy systems and its connectivity is also good. It's available at a low cost, but it's enough to have as many low-cost, more efficient systems as possible. It's a minor thing, but very rarely, it can cause work interruptions while it can get stuck due to more frequent use such as restless work. These power servers are very efficient and really help when things go wrong. I am using this product to retrieve data much faster.

When you need to run a huge number of transactions against big data, reliably, with the minimum total cost of ownership, the solution is the mainframe. If you can build a knowledgeable team around the mainframe, it rocks. Instead of running the serious workload on many, many, many small systems, which is hard to manage by all means of required SMEs, even Datacenter costs, just learn IBM Z and run your workload on the mainframe.

Large high-volume transaction-based systems run well on z/OS. Documentation is good, and support is very good when there is a problem, especially IMS support. IBM should allow many more functions to be offloaded to ziip/zaap than it currently allows. That might help stem the tide of folks wanting to abandon the platform. Allowing more base functions to ziip/zaap might also persuade managers that the platform is not expensive.

IBM Z Is suited for environments that are mission-critical and have a high demand for back-end processing. There is no other platform that can handle huge amounts of workload and is secure and resilient like IBM Z. IBM Z should not be used by small companies or ones that deal with the very little workload. The platform is too expensive for processing small workloads.

1. It is really well suited to handle critical business transactions of processes related to billing and data inventory. 2. Awesome for running batch processes to handles various reconciliation processes 3. Excellent for getting an idea about data analytics If you have legacy data storage or data warehousing applications then integration could be challenging.

IBM Z is well suited for large transactional environments with many input points, such as from computer terminals of an airline in the airports across the world. All of the banking scenarios, claims processing and other styles of environments would be perfect candidates. In addition, Oracle workloads are well suited for this platform, along with traditional DB2 and other Z based supported databases.
