Benefits of IBM Mainframes Today

Benefits of IBM Mainframes Today

In Chapter 3, we explored the enduring advantages of the mainframe environment, tracing back to the launch of IBM S/360. These advantages are encapsulated in the term "qualities of service." This section highlights the benefits associated with the z/OS operating system and mainframe applications.

  • Advanced Workload Management: Optimizes resource allocation to ensure efficient processing of workloads.
  • Centralized Operations and Integrated Systems Management: Simplifies administrative tasks and enhances operational efficiency.
  • Non-disruptive Change Management: Allows for system updates and changes without interrupting services.
  • System Integrity and Security: Provides robust security features to protect against unauthorized access and data breaches.
  • Virtualization and Scalability: Supports virtualization for efficient resource utilization and scalability to meet growing demands.
  • Transaction Processing: Ensures reliable and efficient processing of transactions.
  • Interoperability with Distributed Systems: Facilitates seamless integration with and connection to distributed systems.
  • Colocation of Application Components: Allows for the consolidation of related application components for improved performance.
  • A Single Version of the Truth: Ensures data consistency and reliability across the system.

The System z mainframe has been a cornerstone of high-quality, high-availability services for decades. This enduring reliability is why two-thirds of global business processes are powered by mainframes.
