Overview

Top rule

Open Enterprise SDK for Go 1.16 is an industry-standard Go compiler for the z/OS platform. This offering makes available the popular Go programming language to z/OS application developers. It brings a powerful framework for quickly building scalable applications to the z/OS platform. A simple programming syntax, rich ecosystem of packages, capability to interact with other languages and platforms, and strong community support across multiple industries are driving the popularity of Go.

Open Enterprise SDK for Go 1.16 enables IBM Z® clients to take advantage of this burgeoning technology to power digital transformation on the IBM Z platform. Because of its relatively easy-to-learn syntax, it enables clients to access a wide variety of new talent for application development and modernization. The rich Go ecosystem of packages enables clients to develop and run applications, especially those that enable the cloud on z/OS. Because of the ecosystem of Go modules and the small size of the language's syntax, application developers typically can deliver Go applications in a shorter time and with fewer new lines of code, resulting in lower costs.

As global economic conditions continue to accelerate the need for businesses to focus on digital transformation, the demand for fast, secure, and modern cloud-native applications on the platform continues to increase. This offering enables organizations to add new workloads and connect z/OS to their private cloud, accelerating their digital transformation and journey to hybrid cloud.

Go has emerged as the language of choice for many cloud-native operations. It forms the foundation for container orchestration such as Kubernetes, containerization technology such as Open Container Initiative, and container application platforms such as Red Hat® OpenShift®.

Open Enterprise SDK for Go 1.16 is available without charge from Shopz and is downloadable and installable via the familiar System Modification Program Extended (SMP/E) install tool. There is an option to receive service and support by ordering IBM Subscription and Support for a charge. The ability to obtain service and support means Open Enterprise SDK for Go can be used for production environments.

This delivery demonstrates the longstanding support for open source software by IBM and its commitment to delivering enterprise-level compiler offerings. It also reflects IBM's ongoing effort to advance the z/OS platform.

Description

Top rule

Open Enterprise SDK for Go

Open Enterprise SDK for Go is the latest addition to the IBM family of compiler development tools. It brings a powerful framework for building fast and scalable applications to z/OS, and provides the facility to write applications in support of cloud infrastructures. It can take advantage of the colocation of your data and existing applications on IBM Z to increase throughput and reduce response time. You can control which data will be exposed externally, while keeping all of your proprietary data secure inside the IBM Z platform.

Open Enterprise SDK for Go is available at no charge from Shopz and can be installed using the familiar SMP/E install tool. It is implemented as a 64-bit application on z/OS UNIX® System Services.

Benefits of Go

Open Enterprise SDK for Go brings another popular programming language to the z/OS platform. Application developers say that the Go programming language is the C for the 21st Century. The capabilities and widespread use of Go make it a natural addition to the z/OS as it continues to advance and support application modernization.

A compiled language. Go is a compiled language. When you finish writing your application, your Go source code is converted into machine-level code that can be read directly by z/OS instead of being run through an interpreter every time your application is run.

Go applications are fast. Your source code is converted into an executable file that can be distributed to run the program on other machines. This makes for easier deployment of your applications.

Error checking. As a compiler, Go can check for errors such as variables that are not used, packages that are missing, and even incorrectly typed operators. As a compiler, Open Enterprise SDK for Go helps you to discover errors during the build process rather than at run time.

Garbage collection. One of the key features of the Go language is its capability to perform garbage collection, or automatic memory management. Go provides extensive control over memory allocation.

Scalability, concurrency, and parallelism. Go was designed to support scalability. As applications grow, they need to handle many smaller sub-tasks concurrently. This is especially true for web applications. Running multiple tasks within an application is called concurrency. Go has many built-in features designed to handle concurrency, most notably goroutines and channels.

A goroutine is a function that is capable of running concurrently with another goroutine. Goroutines can be thought of as lightweight threads. They are managed by the Go runtime instead of the operating system and can consume fewer resources.

Channels provide a way for goroutines to communicate with one another and synchronize their execution. Channels can prevent race conditions from occurring, especially when accessing shared memory using goroutines.

The multitasking aspects of concurrency are possible in single-core processors. With multi-core processors and with Go you can raise the concept of concurrency to true parallel programming for increased scalability of your applications.

Simplicity. Go is an easy-to-understand language. The language specification document is small, making the language easy to learn and easy to write.

The main goal of creating Go was to combine the best features of other programming languages, including:

  • Ease of use, together with state-of-the-art productivity
  • High-level efficiency, along with static typing
  • Advanced performance for networking and the full use of multi-core power

Static typing. Go is a statically typed and strongly typed language. This enables Go to catch classes of bugs at compile time rather than at run time. Go has primitive types like int, byte, string, and structs. For your convenience, Go also has built-in types for lists and maps.

Although dynamically typed languages are more flexible and can save you time and space, statically typed languages don't wait until run time to show issues that are often difficult to debug. A statically typed language like Go can provide better performance at run time because the types do not have to be checked dynamically while executing (the typing was already checked before running). A statically typed language can provide better performance at run time because the knowledge of types enables machine code optimization.

Extensive standard library and growing list of third-party packages

Go offers an extensive set of standard libraries and additional third-party packages. Go's large set of standard libraries includes highly used programming tasks in areas like string operations, cryptology, archiving, mail operations, Unicode encoding and decoding, math routines, networking, error manipulation, operating system interfaces, and other popular functions. These packages encourage code reuse.

In addition to the standard library, there is a growing collection of freely available packages from the Go community. These modules are available from the GoPath directory that is accessible from the Golang community website. These packages have been contributed to the Go community by current Go programmers.

With the rich ecosystem of modules in the Go standard library and GoPath directory, application developers can make reuse of these modules to fulfill common programming tasks. Developers can implement business functions with fewer lines of code, which can help to shorten development times and reduce costs. The continued contribution of modules from the community ensures a steady stream of new libraries and tools.

IBM and open source

Originally from Google, Go is now open source and is continually being improved by the open source community. Go boasts an ever increasing and passionate community of coders and enthusiasts. Go's development and support have been driven by the collaboration of this community. There is continual refinement, which helps ensure that Go solutions are as mature as possible. This community also contributes numerous additional modules to the Go collection of packages.

With the initial release of Open Enterprise SDK for Go being an enablement of one of the latest Go community versions, IBM maintains a high level of currency with releases from the Golang open source community. In this way, z/OS clients can enjoy the functionality of latest Go release from Golang.

Value Unit-based pricing

Value Unit pricing for eligible IBM Z IBM International Program License Agreement (IPLA) programs enables a lower cost of incremental growth and enterprise aggregation. Each IBM Z IPLA product with Value Unit pricing has a single price per Value Unit and a conversion matrix, called Value Unit Exhibit, for converting from some designated measurement to Value Units. Most commonly, Millions of Service Units (MSUs) is the measurement designated by IBM to be converted to Value Units. Some other measurements are engines or messages. Since MSUs are the most common measurement, that measurement will be used for the remainder of this description.

Value Unit pricing offers price benefits for you. For each IBM Z IPLA program with Value Unit pricing, the quantity of that program needed to satisfy applicable IBM terms and conditions is referred to as the required license capacity. Each of the various Value Unit Exhibits stipulate that the larger your required license capacity, the fewer Value Units per MSU you will need. Value Unit Exhibits are uniquely identified by a three digit code and referred to using the nomenclature VUExxx, where xxx is the three digit code.

Subsequent acquisitions of Value Unit priced programs offer additional price benefits. The quantity of each IBM Z IPLA program that you have acquired is referred to as entitled license capacity. If you wish to grow your entitled license capacity for an IBM Z IPLA program, the calculation to determine additional needed Value Units is based upon the number of Value Units already acquired.

For each IBM Z IPLA program with Value Unit pricing, you should:

  • Determine the required license capacity, in MSUs.
  • Aggregate the MSUs across the enterprise.
  • Convert the total MSUs to Value Units, using the applicable Value Unit Exhibit.
  • Multiply the price per Value Unit by the total number of Value Units to determine the total cost.

To simplify conversion from the designated measurement to Value Units or vice-versa, use the Value Unit Converter Tool. For additional information or to obtain a copy of the Value Unit Converter Tool, see the IBM Z Software Pricing website.

Note that Value Units of a given program cannot be exchanged, interchanged, or aggregated with Value Units of another program.

To determine the required license capacity for the IBM Z IPLA program you selected, see the Terms and conditions section.

  • The IBM Z IPLA program you select
  • The applicable Value Unit Exhibit
  • The applicable terms
  • Whether your current mainframes are full-capacity or sub-capacity.

For more information on the Value Unit Exhibit for the IBM Z IPLA program you selected, see the Ordering information section.

Program number Program name Terms Parent, if applicable
5655-GOZ IBM Open Enterprise SDK for Go 1.16 Execution-based Not applicable
Full-capacity mainframes

In cases where full capacity is applicable, the following terms apply.

Execution-based, z/OS-based, full machine-based: The required capacity of an IBM Z IPLA program with these terms equals the MSU-rated capacity of the machines where the IBM Z IPLA program executes.

For more information on mainframe MSU-rated capacities, go to the IBM Z software pricing resources webpage.

Reference-based: The required license capacity of a IBM Z IPLA program with these terms equals the license capacity of the applicable monthly license charge (MLC) program. This MLC program is called the parent program.

Sub-capacity mainframes

In cases where sub-capacity is applicable, the following terms apply.

Execution-based: The required capacity of an IBM Z IPLA sub-capacity program with these terms equals the capacity of the LPARs where the IBM Z IPLA program executes.

z/OS-based: The required license capacity of an IBM Z IPLA program with these terms equals the license capacity of z/OS on the machines where the IBM Z IPLA program executes.

Reference-based: The required license capacity of an IBM Z IPLA program with these terms equals the license capacity of the applicable monthly license charge (MLC) program. This MLC program is called the parent program.

Full machine-based: The required license capacity of an IBM Z IPLA program with full machine-based terms equals the MSU-rated capacity of the machines where the IBM Z IPLA program executes.

For more information on mainframe MSU-rated capacities, see the IBM z Systems® Machines Exhibit , Z125-3901, or see the Exhibits section on the IBM Z software pricing resources webpage.

IBM Z IPLA sub-capacity programs with reference-based terms add value to the parent program across the environment, regardless of where in the environment the IBM Z IPLA program executes.

An environment is defined as either a single or stand-alone machine or a qualified Parallel Sysplex®. You may have one or more different environments across the enterprise. To determine the required license capacity for each IBM Z IPLA program with referenced-based terms, each environment should be assessed separately.

When an IBM Z IPLA sub-capacity program with reference-based terms is used in a qualified Parallel Sysplex environment, the required license capacity of the IBM Z IPLA program must equal the license capacity of the parent program across the Parallel Sysplex. Qualified Parallel Sysplex refers to one where MLC pricing is aggregated across the sysplex.

Sub-capacity eligibility

To be eligible for sub-capacity charging on select IBM Z IPLA programs, you must first implement and comply with all terms of one of the following:

  • Sub-capacity Workload License Charges (WLC)
  • Sub-capacity Entry Workload License Charges (EWLC)
  • Sub-capacity Advanced Workload License Charges (AWLC)
  • Sub-capacity Advanced Entry Workload License Charges (AEWLC)

Statement of good security practices

Top rule

IT system security involves protecting systems and information through intrusion prevention, detection, and response to improper access from within and outside your enterprise. Improper access can result in information being altered, destroyed, or misappropriated or can result in misuse of your systems to attack others. Without a comprehensive approach to security, no IT system or product should be considered completely secure and no single product or security measure can be completely effective in preventing improper access. IBM systems and products are designed to be part of a regulatory compliant, comprehensive security approach, which will necessarily involve additional operational procedures, and may require other systems, products, or services to be most effective.

Important: IBM does not warrant that any systems, products, or services are immune from, or will make your enterprise immune from, the malicious or illegal conduct of any party.
