Overall Satisfaction with IBM Z

Mainly IBM Z's versatile platform addressed our wide array of business challenges

1. Deployed to cater to the needs of middleware applications.

2. Focused on the modernization of legacy IT systems which are crucial for business operations and user experiences.

3. Custom in-house applications specific to the Next-generation AI and data analytics

4. Deployed mainly focus on business applications that need robust Reliability and Availability.
  • Linux on Z applications can seamlessly operate on z/OS, which leverages z/OS operations staff and reuse the z/OS environment.
  • Primarily container images with s390x architecture in the Docker Hub can
  • be run in z/OS Container Extensions.
  • Kafka alongside with ZooKeeper API, benifits from the centralized service that maintains configuration information.
  • Unfortunately, there is no provision of morethan one one network interface in each virtual server instance of z/OS systems
  • As a limitation at resource sharing, mainly Disks are not able to share between z/OS virtual server instances
  • Compression is one of the key feature should be included to support in the PCIe
  • IBM App Connect Enterprise for zCX on z/OS leverages the flexibility to integrate z/OS
  • subsystems close to the source and targets, including IIMS, Db2, CICS and IBM MQ.
  • Using niche features of Ansible cloud provisioning, writing many commands to deploy containers, such as in Jenkins, automation jobs in Ansible are described in YAML playbooks
  • IBM Service Management Unite (SMU) Automation for Workload Scheduling
  • Initial setup cost if high on the budget, but considering the logivity of the product its reasonably acceptable to generate a decent ROI on the Z system portfolio.

Do you think IBM Z delivers good value for the price?

Yes

Are you happy with IBM Z's feature set?

Yes

Did IBM Z live up to sales and marketing promises?

Yes

Did implementation of IBM Z go as expected?

Yes

Would you buy IBM Z again?

Yes

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.
