Mainframes

TL;DR

Enterprise-grade systems used to process very large volumes of data in real time.
Valued for high reliability, security, and performance.
Typically expensive and require specialized skills to operate and maintain.

Definition

A mainframe is a large, high-powered computer that is capable of handling and processing vast amounts of data and information quickly and efficiently.

Explanation

Mainframes are designed to manage and process large quantities of data with high throughput and low latency, making them suitable for real-time processing demands. They deliver strong security, reliability, and performance and are often deployed by organizations with substantial data-processing needs. Mainframes can support both traditional mainframe applications and, in some cases, emerging technologies.

Examples

IBM System z

The IBM System z is a powerful, scalable mainframe that can handle a wide range of workloads, from traditional mainframe applications to emerging technologies like artificial intelligence and cloud computing. The System z is built on IBM’s advanced hardware and software technologies and offers high levels of security, reliability, and performance.

Unisys ClearPath Dorado

The Unisys ClearPath Dorado is a mainframe specifically designed for mission-critical applications. The ClearPath Dorado is built on Unisys’ proprietary technology and offers high levels of security, reliability, and performance. It is used by organizations in a wide range of industries, including finance, healthcare, and government.

Use cases

Banks, insurance companies, and government agencies that need to process large amounts of data in real time.
Organizations in finance, healthcare, and government for mission-critical workloads.

Notes or pitfalls

Mainframes are expensive and require specialized skills to operate and maintain, which can make them less appealing to smaller organizations or those with limited budgets.
Despite cost and staffing requirements, mainframes can be essential tools for organizations with large, real-time data-processing needs.
