Open Enterprise SDK for Go Modernization Guide

The Open Enterprise SDK for Go enables z/OS application development using the Go programming language. It provides a compiler, runtime environment, and standard libraries optimized for the z/OS platform.

The SDK supports compiling Go code for execution on z/OS. It allows developers familiar with Go to create and maintain applications on the mainframe.

The SDK includes the `go` command-line tool, standard Go libraries, and z/OS-specific extensions. It also provides documentation and samples to help developers get started.

The primary command is `go`, used for compiling, building, testing, and running Go programs. For example, `go build` compiles the current package, and `go run main.go` executes the main function in `main.go`.

The SDK uses standard Go configuration files, such as `go.mod` for managing dependencies. Environment variables like `GOROOT` and `GOPATH` are also used to configure the Go environment.

The SDK primarily supports native Go APIs. It allows Go programs to interact with z/OS system services and resources through Go language bindings.

The SDK supports integration with other z/OS components through standard Go networking libraries and system call interfaces. It uses TCP/IP for network communication.

The Open Enterprise SDK for Go enables developers to leverage their Go skills to build and maintain applications on z/OS, potentially reducing development costs and time.

By using Go, organizations can modernize their z/OS applications and integrate them with other systems and platforms that support Go.

The SDK allows organizations to attract and retain developers familiar with Go, expanding the talent pool for z/OS development.

The SDK leverages z/OS security features for authentication and authorization. Specific authentication methods include those supported by z/OS, such as RACF.

The access control model is based on z/OS security mechanisms, such as RACF, which provides role-based access control (RBAC).

The SDK supports encryption using z/OS cryptographic services. Data can be encrypted in transit using TLS and at rest using z/OS data set encryption.

The SDK integrates with z/OS audit and logging facilities, providing detailed logs of system events and user activities. These logs can be used for security monitoring and compliance.

The SDK can be administered through z/OS system administration tools and interfaces. User management is handled through z/OS security systems like RACF.

Key configuration parameters include settings for the Go runtime environment, such as memory allocation and garbage collection. These can be configured through environment variables and Go program settings.

The SDK provides monitoring and logging capabilities through z/OS system monitoring tools and Go logging libraries. System events and application logs can be monitored for performance and troubleshooting.
