The IBM System Z server (Mainframe) is the system of record
for most Fortune 1000 companies, housing critical business data as well as PII data
from customers that must be available at all times but cannot be compromised.
The Mainframe platform is behind just about every critical user experience in
business today. For this reason, every company shares common concerns about the
security of their customer data and the compatibility and performance of the
applications that drive their business.
What is Zowe?
Zowe is an open source project for the Mainframe. Alike Mac OS or
Windows, Zowe comes with a set of APIs and OS capabilities that application
developers can leverage. Zowe also includes some application samples and
applications out of the box.

Zowe main components
Zowe Application
Framework: A web user interface (UI) that provides a virtual desktop
containing a number of apps allowing access to z/OS function. Base Zowe
includes apps for traditional access such as a 3270 terminal and a VT Terminal,
as well as an editor and explorers for working with JES, MVS Data Sets and Unix
System Services.
API Mediation Layer: Provides
a gateway that acts as a reverse proxy for z/OS services, together with a
catalog of REST APIs and a dynamic discovery capability. Base Zowe provides
core services for working with MVS Data Sets, JES, as well as working with
z/OSMF REST APIs. The API Mediation Layer also provides a framework for Single
Sign On (SSO).
Zowe CLI: Provides
a command-line interface that lets you interact with the mainframe remotely and
use common tools such as Integrated Development Environments (IDEs), shell
commands, bash scripts, and build tools for mainframe development. It provides
a set of utilities and services for application developers that want to become
efficient in supporting and building z/OS applications quickly. The CLI
provides a core set of commands for working with data sets, USS, JES, as well
as issuing TSO and console commands.
Where to start?
The installation of Zowe™ consists of two independent
processes:
- installing Zowe runtime on z/OS
- Install the Zowe Application Framework, the API Mediation Layer, and a number of micro services that provide capability to both.
- Install the Zowe Cross Memory Server. This is an authorized server application that provides privileged services to Zowe in a secure manner.
- installing Zowe CLI on your computer (The Zowe CLI is not installed on z/OS and runs on a personal computer)
