This blog aims to provide an introduction, a high level overview, to IBM zD&T, discussing its components, features, and steps to start learning and utilizing it effectively.
Understanding IBM zD&T
IBM zD&T, also known as IBM z Systems Development and Test Environment, is a comprehensive solution designed to facilitate mainframe application development, testing, and training without the need for dedicated mainframe hardware. It allows developers to create, deploy, and test mainframe applications in a virtualized environment, replicating the functionalities of an IBM z System.
Components of IBM zD&T
1. Management Console: This web-based interface serves as the central hub for managing virtualized mainframe environments. From here, users can create, configure, and monitor virtual machines, networks, and storage resources.
2. Emulator: The emulator replicates the behavior of an IBM z System, enabling developers to run mainframe operating systems, such as z/OS, z/VM, and z/VSE, on standard x86-based servers. It provides a highly accurate simulation of mainframe hardware, including processors, memory, and I/O devices.
3. Operating Systems: IBM zD&T supports various mainframe operating systems, allowing developers to choose the environment that best suits their needs. These include z/OS, IBM's flagship mainframe operating system, as well as z/VM (Virtual Machine) and z/VSE (Virtual Storage Extended).
4. Development Tools: IBM zD&T comes with a range of development tools and utilities tailored for mainframe development, including compilers, debuggers, and performance analysis tools. These tools enable developers to write, compile, debug, and optimize mainframe applications efficiently.
5. Integration with DevOps Tools: To streamline the development process, IBM zD&T integrates seamlessly with popular DevOps tools and frameworks, such as Jenkins, Git, and IBM UrbanCode Deploy. This integration allows for automated build, test, and deployment pipelines, ensuring rapid and reliable delivery of mainframe applications.
