Keeping it simple
Linux on System z is all about helping to remove complexity from your IT infrastructure: reducing server sprawl, keeping a lid on software licensing fees and minimizing the need for human intervention in managing and maintaining your servers.
While Linux brings advantages to all the platforms that it runs on, choosing the IBM mainframe for Linux applications adds the mainframe core strengths that distinguish the mainframe from the other platforms.
Here are the key capabilities of Linux on System z that make this possible:

Virtualization technology is built into every server in the System z line. It allows you to create and manage discrete virtual processors and communications, storage and I/O devices in a single System z server. These resources can be dynamically shared or reconfigured, helping to simplify the demands placed upon you to plan, purchase and install new hardware to handle new workloads. Also remarkable is the speed with which System z virtualization technology allows you to create and deploy virtual Linux servers-minutes rather than days. This can help accelerate your project schedules and, ultimately, time to market.

Linux, built on open standards, provides the flexibility to make it easier for multiple applications and middleware to work together to deploy new solutions more quickly, and process transactions and data more efficiently. The leading-edge System z technology and coexistence with z/OS, z/OS.e, z/VM, z/TPF and z/VSE is designed to provide high-speed connections among heterogeneous applications in the same server. These high-speed connections called HiperSockets, can be described as an in-storage implementation of a TCP/IP network. By reducing the need for an external network, HiperSockets helps you reduce costs, and complexity, and since all of the communication takes place within the System z server, security is improved as well. The result is a highly integrated environment designed to be free of barriers to information sharing, allowing your business to become more responsive, flexible and efficient, which can help you to get a unified view of your customers and competitors, launch new products faster and process transactions more smoothly.

Advanced System z system management tools are designed to provide the proper amount of resource to the most important applications when needed. The VM Resource Manager lets users assign performance goals to help ensure that your on-demand business meets demands for service. And, Linux together installed with z/OS allows you to take advantage of the z/OS Workload Manager, which can manage the logical partition that Linux is running in, and in concert with the Intelligent Resource Manager to dynamically balance your computing resources to your workloads, to help you to be prepared for spikes in demand. Big jobs get the muscle they need, and small jobs only what they need, keeping utilization and availability high. Virtualization software gives you a single point of system management control, helping to minimize errors and, by extension, effort and costs. And innovative self-configuring, self-healing, self-optimizing and self-protecting features built into every System z server can keep your system running at peak performance with a minimum of human intervention.

System z provides a highly secure Linux platform. System z servers today are the result of over forty years of innovation. Designed to be rugged, resilient, highly available and highly secure, System z servers are often entrusted with the most important, mission critical applications and data that drive a company. Autonomic attributes are designed to allow your machine to be there when you need it, and you can add compute power to a System z server to meet unexpected demand when you need it. Also, virtual Linux servers on System z are isolated, so you can run multiple, heterogeneous workloads simultaneously. Linux on System z solutions can also incorporate several industry-leading security features, such as enhanced cryptography support designed to allow e-business transactions to remain private and secure. Linux, leveraging the mainframe strength, is evolving to an even higher level of quality.
