What is Zowe?

Zowe offers modern interfaces to interact with z/OS and allows you to work with z/OS in a way that is similar to what you experience on cloud platforms today. You can use these interfaces as delivered or through plug-ins and extensions that are created by clients or third-party vendors.

Zowe consists of the following main components.

Zowe App Framework

Contains a Web user interface (UI) that provides a full screen interactive experience. The Web UI includes many interactions that exist in 3270 terminals and web interfaces such as IBM z/OSMF.

Explorer server

Provides a range of APIs for the management of jobs, data sets, z/OS UNIX System Services files, and persistent data.

API Mediation Layer

Provides an API abstraction layer through which APIs can be discovered, catalogued, and presented uniformly.

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.
