Glossary

Find terms that you might be interested to know when you use IBM® Wazi as a Service.

access control list

A list that statelessly manages inbound and outbound traffic for a subnet through the use of rules. An access control list helps provide security at the subnet level.

cloud resource name (CRN)

A globally unique identifier for a specific cloud resource. The value is segmented hierarchically by version, instance, type, location, and scope, separated by colons.

component

A collection of artifacts, such as volumes, from an IBM Z platform. A component is reusable with different components to create more than one image.

compute

Infrastructure or resources that serve as the basis for building apps in the cloud.

Custom Resource

Custom Resource (CR) objects are created from CRDs that have been added to the cluster by a cluster administrator, allowing all cluster users to add the new resource type into projects.

While only cluster administrators can create CRDs, developers can create the CR from an existing CRD if they have read and write permission to it.

Custom resource definition

A custom resource definition (CRD) object defines a new, unique object type, called a kind, in the cluster and lets the Kubernetes API server handle its entire lifecycle.

data center (DC)

The physical location of the servers that provide cloud services.

data sets

In z/OS, a named collection of related data records stored and retrieved by an assigned name. Equivalent to a file.

devfile

A portable file that describes your development environment. With the devfile, you can define a portable developmental environment, such as the source code, IDE tools, application runtimes, and predefined commands, without the need for reconfiguration.

experimental offering

An offering that IBM makes available solely for evaluation and testing purposes, and might be unstable or not compatible with previous versions. An experimental offering can be discontinued with short notice. There are no warranties, SLAs or support provided, and experimental offerings are not intended for production use.

floating IP address

A public, routable IP address that makes use of 1-to-1 network address translation (NAT) so that a server can communicate with the public internet and private subnet within a cloud environment. Floating IP addresses are associated to an instance, for example, a virtual server instance, a load balancer, or a VPN gateway, by means of a virtual network interface card (vNIC).

globally unique identifier (GUID)

An algorithmically determined number that uniquely identifies an entity within a system.

hybrid cloud

A cloud computing environment that consists of multiple public and private resources.

IBM Wazi for Eclipse

IBM Wazi for Eclipse is an Eclipse-based modern, lean integrated development environment with program understanding, edit, debug, and build automation capabilities.

Identity and Access Management (IAM)

The process of controlling access of authorized users to data and applications, while helping companies comply with various regulatory requirements.

image

A collection of components that are packaged together as a single deliverable. An image contains the z/OS core system and user-selected z/OS applications and subsystems and is used to be deployed to your target environment.

Image storage server

A type of server that can be used to store z/OS images for Sandbox instances. Sandbox uses SSH File Transfer Protocol (SFTP) server as the image storage server, and stores ADCD images on the server.

initial program load (IPL)

An initial program load (IPL) is the act of loading a copy of the operating system from disk into the processor’s real storage and executing it.

instance

A z/OS instance that is running on an emulated IBM Z hardware from a created image.

Interactive System productivity Facility (ISPF)

The menu-drive interface that offers a wide rang of functions to assist users in working with data files on the z/OS system.

Job Control Language (JCL)

JCL is the command language in z/OS. JCL identifies the program to be executed, the inputs that are required and location of the input/output and informs the Operating System through Job control Statements. In mainframe environment, programs can be executed in batch and online modes. JCL is used for submitting a program for execution in batch mode. JCL is core to development activities, and batch workload is core to all users.

JES 2

A z/OS subsystem that receives jobs into the system, converts them to internal format, selects them for execution, processes their output, and purges them from the system. In an installation with more than one processor, each JES2 processor independently controls its job input, scheduling, and output processing.

Microsoft Visual Studio Code (VS Code)

A code editor redefined and optimized for building and debugging modern web and cloud applications. Visual Studio Code is free and available on Linux®, macOS, and Windows.

profile

A collection of controls used to evaluate whether technology and services are configured in compliance with security policies.
A specification of a resource's capacities and capabilities. Different profiles are optimized for different workloads and use cases. A resource's pricing model might depend on its profile.

quota

The number of resources that can be consumed at an account or service instance level.

Red Hat OpenShift Dev Spaces (formerly Red Hat CodeReady Workspaces)

Red Hat OpenShift Dev Spaces provides a powerful and familiar in-browser IDE with support for Microsoft Visual Studio Code extensions. Developers need only a machine capable of running a web browser to code, build, test, and run on OpenShift.

Red Hat OpenShift

Red Hat OpenShift is a hybrid cloud, enterprise Kubernetes application platform.

route

A route allows developers to expose services through an HTTP(S) aware load balancing and proxy layer via a public DNS entry. An administrator typically configures their router to be visible outside the cluster firewall and can also add additional security, caching, or traffic controls on the service content.

SCM

SCM refers to Software Configuration Management or Source Code Management. It refers to the task of tracking and controlling changes in the software. SCM practices include revision control and the establishment of baselines. If something goes wrong, SCM can determine what was changed and who changed it.

Secret

The Secret object type provides a mechanism to hold sensitive information such as passwords, OpenShift Container Platform client configuration files, private source repository credentials, and so on. Secrets decouple sensitive content from the pods.

security group

A resource that provides rules to filter IP traffic to resources in a virtual private cloud. Rules are stateful, such that packets in response to allowed packets are automatically permitted.

server configuration file

A file (in XML format) used by the SHK Sentinel Key Server to obtain networking and logging parameters. It is at this location: /opt/safenet_sentinel/common_files/sentinel_keys_server/Sntlconfigsrvr.xml

Software-based License Server update file

The specific license key file that is generated in the Rational License Key Center and installed on a Software-based License Server by using an update_license command. This file is used for software-based licensing.

UUID

A universally unique identifier. It is obtained from the Intel machine BIOS. It is used to uniquely associate a UIM serial number with a particular machine.

virtual private cloud (VPC)

A virtual network that is tied to a private user account and isolated from other networks in a public cloud. Only authorized users can access virtual private cloud resources, which include virtual servers, storage, and subnets.

virtual private network (VPN)

A private connection between two endpoints, even when the data is transferred across a public network. Usually, a VPN is used in combination with security methods, such as authentication and encryption, to provide maximum data security and privacy.

Zowe, like Mac or Windows, comes with a set of APIs and OS capabilities that applications build on and also includes some applications out of the box. Zowe offers modern interfaces to interact with z/OS, with which you can 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.
