DevOps Toolchain
Successful DevOps implementations generally rely on an integrated set of solutions or a "toolchain" to remove manual steps, reduce errors, increase team agility, and to scale beyond small, isolated teams. Tools build, deploy, and manage your apps. You can create toolchains that include IBM Cloud services, open source tools, and third-party tools that make development and operations repeatable and easier to manage.
common use cases for dev ops include: cloud native and mobile applications, application integration, and modernization and multicloud management.

key features of UrbanCode Release
Allocate environments Track releases to their particular environments to help ensure that code is deployed to the appropriate environment. Define unique process requirements for specific environments. Perform both repeatable environment-specific tasks and configuration tasks that are only executed once. Define a release Identify the set of applications that will participate in a release. Define release-process checklist items such as documentation reviews, project kickoff dates, and release-ready review dates. Create a lifecycle template Construct a reusable release process template (called a "lifecycle") to describe the path to production through the development and testing phases. Define lifecycles for different types of releases and business units. Specify quality gates to help ensure the software meets the specified criteria for a phase before being deployed into an environment. Gain greater visability Gain visibility into every part of the release with the reusable deployment plan. Track tasks assigned to users, roles, and automated systems. Automatically disseminate plan changes to other scheduled deployments that use the same master plan. Support simplified plans for continuous delivery in early integration and testing environments.
IBM® Cloud Continuous Delivery provides two types of delivery pipelines that you can use to build, test, and deploy your applications.
Classic - Classic delivery pipelines are created graphically, with the status embedded in the pipeline diagram. These pipelines can run on shared workers in the cloud or on private workers that run on your own Kubernetes cluster. Tekton - Tekton delivery pipelines are created within yaml files that define pipelines as a set of Kubernetes resources. You can edit those yaml files to change the behaviour of a pipeline. Tekton pipelines can run on private workers that run on your own cluster. They can also run on IBM-managed workers on the public cloud. The Tekton integration provides a dashboard that you can use to view the output of Tekton pipeline runs. It also provides mechanisms for identifying the pipeline definitions repo, the pipeline triggers, where the pipeline runs, and the storage and retrieval of properties.
Web IDEFeatures
Code hints for node js code Completion Run Bar - You can quickly build and deploy your application to a test environment on IBM Cloud without committing your code to the Git repository. If you are building a Node.js application, you can use IBM Cloud Live Sync to quickly update the application instance on IBM Cloud and develop without redeploying. When you make a change, you can see that change in your running IBM Cloud application immediately (without the need to recompile and redeploy).
Git Repos and Issue Tracking on IBM Cloud
Collaborate with your team and manage your source code with a Git repository (repo) and issue tracker that is hosted by IBM and built on GitLab Community Edition.
key fundamental aspects of an agile team.
Communication between team members, management, and cross-team to discuss rapid change. Introspective opportunities, or team retrospectives, where team members can discuss what went well, what went poorly, and what needs improvement. A flexible, adaptive way of working when projects require quick, unexpected changes. Self-organizing and self-sufficient ways of working that allow teams to assign their own tasks and sprint goals and estimates. Collaboration and independent management amongst team members to improve delivery.
Continuous Integration benefits
Continuous and demonstrated progress for improved feedback Early and improved error detection that lets you address errors early—sometimes within minutes of check-in Improved team collaboration so they know they can change the code, integrate the system, and quickly determine conflicts with other parts of the software System integration that reduces surprises at the end of the software development lifecycle Fewer changes for merging and testing Reduced number of errors during system testing Constantly updated systems to test against
Continuous Delivery
Continuous delivery (CD) is another DevOps practice that focuses on delivering any validated changes to code—updates, bug fixes, even new features—to users as quickly and safely as possible. Continuous delivery picks up where continuous integration ends, automating the delivery of applications to selected infrastructure environments. It ensures automated pushing of code changes to different environments, such as development, testing, and production.
Continuous Integration
Continuous integration (CI) is a shared software development and DevOps practice of integrating code regularly into repositories. Quickly and easily detect errors within your code to keep your team agile and efficient. Continuous integration is a process for accomplishing agile development. Continuous integration is a software development process where developers integrate their code more frequently—at least once a day—in order to identify integration issues earlier, when they are easier to fix. Overall, continuous integration helps you reduce your code development effort, resulting in higher-quality software and more predictable delivery schedules.
Continuous Integration Methodology
Continuous integration requires you to integrate work frequently, which leads to multiple integrations each day. You verify integration by an automated build that detects integration errors as early as possible. The build should include tests as part of verification.

different DevOps tools.
IBM Architecture Room Live is used to design and communicate new architectures. It is a browser-based design and architecture tool allowing real-time, multi-user, multi-site collaboration via a virtual architecture "whiteboard." IBM Rational Test Workbench is used to virtualize the test environment dependencies that are not available when the team needs to start testing. It enables the creation, execution, and reporting of the quality of the integration, functional and performance capabilities as well as the end to end business and technical scenarios. IBM UrbanCode Deploy is used to automate the deployment of software to different environments. It mitigates the risk of managing multiple application configurations, integrations, and versions across many ecosystems. IBM UrbanCode Velocity is used to orchestrate the overall delivery of the entire software solution. It provides insight into how value flows through each delivery pipeline and highlights where bottlenecks are disrupting the flow.
IBM Garage Methodology
IBM Garage Methodology is foundational to the IBM Garage and is a unique methodology that curates industry best practices layered with a depth of experience only IBM can bring.
IBM UrbanCode Release Automation
IBM UrbanCode® Release is a collaborative release management solution that helps you plan, execute and track a release through every stage of the delivery lifecycle. With UrbanCode Release you can manage the release of interdependent applications, infrastructure changes, and simultaneous deployments of multiple applications.
DevOps principles include:
Improved processes that truncate feedback loops to continuously implement needed bug fixes and vulnerability remediation earlier and more cost-effectively Continual experimentation that encourages risk-taking and learning from success and failure, so continuous attempts will lead to future success and mastery Learners becoming teachers and passing along their acquired knowledge to their colleagues Using DevOps automation to improve efficiency Giving continuous feedback to the entire organization Incentivizing development, test, and deployment teams to collaborate on shared goals
benefits for integrating systems frequenlty
Integration issues identified earlier, when they are easier to fix more predictable delivery schedules higher quality product the overall integration effort is reduced
Continuous Integration Best Practices
Maintain a single source repository Automate the build Use (at least) daily mainline commits Test in a clone of the production environment Automate deployment
The Git Repos and Issue Tracking tool integration supports teams to manage code and collaborate in many ways by
Manage Git repositories through fine-grained access controls that keep code secure Review code and enhance collaboration through merge requests Track issues and share ideas through the issue tracker Document projects on the wiki system
Creating Toolchains
Open toolchains are available in the Public and Dedicated environments on IBM Cloud®. You can create a toolchain in two ways: use a template to create a toolchain or create a toolchain from an app. Each toolchain is associated with a specific resource group or organization (org). If a toolchain is associated with a resource group, any user that has Identity and Access Management (IAM) Viewer permission for the toolchain resource or the resource group that contains it can access the toolchain.
Jobs (build, deploy, and test) are grouped into stages.
Run By default, IBM Cloud Continuous Delivery automatically runs the build and deploy tasks when you commit changes to the Git repository. The pipeline also features a "run" icon that runs a stage of the pipeline but only runs on committed code or builds, depending on the stage. View Toolchain You can access the Continuous Delivery toolchain by clicking View toolchain from the Application Details page. To browse to the delivery pipeline (or any other tool), click its tool card in the toolchain overview page. Jobs Jobs (Build, Deploy, and Test) are grouped into stages. You can change the order of the stages by moving them by dragging and dropping.
Continuous Deployment
While "continuous deployment" and "continuous delivery" may sound like the same thing, they are actually two different approaches to frequent release. Continuous delivery is a software development practice where software is built in such a way that it can be released into production at any given time. Continuous deployment takes automation a step further and removes the need for manual intervention. Continuous deployment takes automation a step further and removes the need for manual intervention. Continuous deployment is the natural outcome of continuous delivery done well. Eventually, the manual approval delivers little or no value and is merely slowly things down. At that point, it is done away with and continuous delivery becomes continuous deployment.

DevOps
an increasingly common approach to agile software development that developers and operations teams use to build, test, deploy and monitor applications with speed, quality and control. DevOps is relevant to any kind of software project regardless of architecture, platform or purpose. DevOps enables fast and automated deployment of services.
