DevOps is becoming the latest revolution in the field of Information Technology. DevOps is an extension of agile principles which focuses of user's satisfaction. DevOps is a mix of Product Development, Quality Assurance, and System Operation. It brings down the silos between these departments to increase efficiency in the products of an enterprise.
Nowadays, more and more enterprises are embracing DevOps for its advantages. This presentation is just an introduction of DevOps. People who don't have a deep understanding of computer & IT concepts, can easily follow the commentary on DevOps in this presentation.
DevOps is an approach where one size does not fit all organizations. It involves the constant adaption of new technologies and tools for a seamless experience. The significant advancements in the tools used for DevOps implementation are a sign that DevOps will continue to evolve in the future. For example, Kubernetes is now used along with Docker to improve automated deployment and management. DevOps has further branched out to services like DevSecOps, QAOps, SecDevOps, MLOps , and much more.
Kubernetes: A Top Notch Automation SolutionFibonalabs
Kubernetes is a portable, extensible open-source platform that facilitates automated deployment, scaling, and management of Linux containerized applications. It was developed by Google, written using the GO language. It is a PaaS(Platform as a Service) when used on the cloud, whereas it is also flexible as an IaaS(Infrastructure as a Service) and SaaS(Software as a Service) by enabling portability, simplified scaling, and provision of robust software models.

Cloud-Native Fundamentals: Accelerating Development with Continuous IntegrationVMware Tanzu
DevOps. Microservices. Containers. These terms have a lot of buzz for their role in cloud-native application development and operations. But, if you haven't automated your tests and builds with continuous integration (CI), none of them matter.
Continuous integration is the automation of building and testing new code. Development teams that use CI can catch bugs early and often; resulting in code that is always production ready. Compared to manual testing, CI eliminates a lot of toil and improves code quality. At the end of the day, it's those code defects that slip into production that slow down teams and cause apps to fall over.
The journey to continuous integration maturity has some requirements. Join Pivotal's James Ma, product manager for Concourse, and Dormain Drewitz, product marketing to learn about:
- How Test-Driven Development feeds the CI process
- What is different about CI in a cloud-native context
- How to measure progress and success in adopting CI
Dormain is a Senior Director of Product and Customer Marketing with Pivotal. She has published extensively on cloud computing topics for ten years, demystifying the changing requirements of the infrastructure software stack. She’s presented at the Gartner Application Architecture, Development, and Integration Summit; Open Source Summit; Cloud Foundry Summit, and numerous software user events.
James Ma is a product manager at Pivotal and is based out of their office in Toronto, Canada. As a consultant for the Pivotal Labs team, James worked with Fortune 500 companies to hone their agile software development practices and adopt a user-centered approach to product development. He has worked with companies across multiple industries including: mobile e-commerce, finance, heath and hospitality.

Intro to GitOps with Weave GitOps, Flagger and LinkerdWeaveworks
You may not think of "GitOps" and "service mesh" together – but maybe you should! These two wildly different technologies are each enormously capable independently, and combined they deliver far more than the sum of their parts: a single Git commit can control workflows customized for your exact situation by taking advantage of the service mesh's ability to measure and manipulate traffic anywhere in your application's call graph, and you can rest easy knowing that Git is preserving the complete configuration for your entire application every step of the way.
See how these technologies can work together to tackle complex problems in cloud-native applications.
What you’ll get out of this:
* Understand what GitOps and service meshes can - and can't - do for you.
* Understand basic operations with GitOps and Linkerd.
* Understand the basics of continuous deployment with Weave GitOps and Linkerd.

Webinar: Capabilities, Confidence and Community – What Flux GA Means for YouWeaveworks
Flux, the original GitOps project, began its development in a small London office back in 2017 with the goal to bring continuous delivery (CD) to developers, platform and cluster operators working with Kubernetes. From donating the project to the CNCF, its continued growth within the cloud native community, to its achievement of passing rigorous battle tests for security, longevity and governance, it’s little wonder that Flux v2 has reached yet another celebratory milestone – General Availability (GA).
Flux is the GitOps platform of choice for many enterprise companies such as SAP, Volvo Cars, and Axel Springer; and is embedded within AKS, Azure Arc and EKS Anywhere. It provides extensive automation to CI/CD, security and audit trails, and reliability through canary deployments and rollback capabilities.
Join this webinar by Flux maintainers and creators and discover:
* Latest release features and roadmap for the future.

What is DevOps Services_ Tools and Benefits.pdfkomalmanu87
This closer relationship between “Dev” and “Ops” permeates every phase of the DevOps lifecycle: from initial software planning to code, build, test, and release phases and on to deployment, operations, and ongoing monitoring. This relationship propels a continuous customer feedback loop of further improvement, development, testing, and deployment. One result of these efforts can be the more rapid, continual release of necessary feature changes or additions.
What is DevOps Services_ Tools and Benefits.pdfkomalmanu87
Some people group DevOps goals into four categories: culture, automation, measurement, and sharing (CAMS), and DevOps tools can aid in these areas. These tools can make development and operations workflows more streamlined and collaborative, automating previously time-consuming, manual, or static tasks involved in integration, development, testing, deployment, or monitoring.
Help students get familiar with the basic concepts of DevOps processes and technologies and the challenges facing companies who are looking to embrace scalable software deployment.

Understanding the GitOps Workflow and CICD Pipeline - What It Is, Why It Matt...Gibran Badrulzaman
Travelio Tech Talks 2022 presentation
The recommended workflow for implementing GitOps with Kubernetes manifests is known as trunk-based development. This method defines one branch as the "trunk" and carries out development on each environment in a different short-lived branch. When development is complete for that environment, the developer creates a pull request for the branch to the trunk. Developers can also create a fork to work on an environment, and then create a branch to merge the fork into the trunk.
Once the proper approvals are done, the pull request (or the branch from the fork) gets merged into the trunk. The branch for that feature is deleted, keeping your branches to a minimum. Trunk-based development trades branches for directories.
You can think of the trunk as a "main" or primary branch. production and prod are popular names for the trunk branch.
Trunk-based development came about to enable continuous integration and continuous delivery by supplying a development model focused on the fast delivery of changes to applications. But this model also works for GitOps repositories because it keeps things simple and more in tune with how Kustomize and Helm work. When you record deltas between environments, you can clearly see what changes will be merged into the trunk. You won’t have to cherry-pick nearly as often, and you’ll have the confidence that what is in your Git repository is what is actually going into your environment. This is what you want in a GitOps workflow.

Climate Science Flows: Enabling Petabyte-Scale Climate Analysis with the Eart...Globus
The Earth System Grid Federation (ESGF) is a global network of data servers that archives and distributes the planet’s largest collection of Earth system model output for thousands of climate and environmental scientists worldwide. Many of these petabyte-scale data archives are located in proximity to large high-performance computing (HPC) or cloud computing resources, but the primary workflow for data users consists of transferring data, and applying computations on a different system. As a part of the ESGF 2.0 US project (funded by the United States Department of Energy Office of Science), we developed pre-defined data workflows, which can be run on-demand, capable of applying many data reduction and data analysis to the large ESGF data archives, transferring only the resultant analysis (ex. visualizations, smaller data files). In this talk, we will showcase a few of these workflows, highlighting how Globus Flows can be used for petabyte-scale climate analysis.
How to Position Your Globus Data Portal for Success Ten Good PracticesGlobus
Science gateways allow science and engineering communities to access shared data, software, computing services, and instruments. Science gateways have gained a lot of traction in the last twenty years, as evidenced by projects such as the Science Gateways Community Institute (SGCI) and the Center of Excellence on Science Gateways (SGX3) in the US, The Australian Research Data Commons (ARDC) and its platforms in Australia, and the projects around Virtual Research Environments in Europe. A few mature frameworks have evolved with their different strengths and foci and have been taken up by a larger community such as the Globus Data Portal, Hubzero, Tapis, and Galaxy. However, even when gateways are built on successful frameworks, they continue to face the challenges of ongoing maintenance costs and how to meet the ever-expanding needs of the community they serve with enhanced features. It is not uncommon that gateways with compelling use cases are nonetheless unable to get past the prototype phase and become a full production service, or if they do, they don't survive more than a couple of years. While there is no guaranteed pathway to success, it seems likely that for any gateway there is a need for a strong community and/or solid funding streams to create and sustain its success. With over twenty years of examples to draw from, this presentation goes into detail for ten factors common to successful and enduring gateways that effectively serve as best practices for any new or developing gateway.

1. A Mindtree Whitepaper
GitLab is one of the most popular DevOps platforms, and provides an
ecosystem for code and release management and the pipeline tools for
end-to-end management. In this whitepaper, we discuss the methods
and best practices to implement DevOps using the GitLab ecosystem,
and cover its tools, branching strategy and design.
GitLab-based
DevOps Platform
2. GitLab Tools
GitLab is a full-fledged DevOps system that provides a software repository, CI/CD system, user management
and monitoring from a single ecosystem as a Software as a Service (SaaS) offering with industry standard
end-to-end security.
Apart from traditional command line tools, it provides webUI for both operations, maintenance and
performing regular branching, tagging, merging and any other Git operations. These rich user interfaces are
available for CI/CD pipeline monitoring, status check and configurations as well.
GitLab enables high flexibility to integrate most other third party tools such as SonarQube, build scripts for
the most modern technology stacks and automation, as well as deployment plugins to cloud labs such as
Firebase Cloudlab and BrowserStack. Apart from regular environment-based deployment in cloud hosting, it
also supports multi-cloud based deployment.
The GitLab DevOps ecosystem ensures continuous feedback, which is a key need for agile development.
We have depicted the GitLab ecosystem in Figure 1.

3. Plan & Create
As part of plan and create program, the manager plans the release and defines milestones. The business
analysts author user stories and collaborate with team members.
Software Repository
A version-controlled software code management system that is easy to create and manage with workflows
for each solution tenant in the architecture. The repository’s access is supported with industry standard
security like user management with role-based access management, multi factor authentications and SSL
handshakes. This code base can be configured with workflows and branching strategies, while code review
stages can be defined by integration to internal or external tools.
GitLab Pipeline[CI/CD]
The crux of the solution support for a whole devops ecosystem is provided via the GitLab pipeline, where a
continuous integration and continuous deployment is managed. Modern solutions such as a docker
container-based scalable DevOps build pipelines are available with a flexibility of integrating a private runner
or an on-premises / local build system. Multi-cloud-based solution deployment is supported with ease, while
enough plugins and tools are available that will help assess the code quality. Additionally, automated test
cases can be executed, while release management is supported via build deployment to environments or
external distribution entities such as appcenter, testflight, Play Store and app stores.
Issue Tracking
Monitoring and issue tracking is supported, which helps tag/manage issues. The release supports continuous
delivery in addition to continuous integration and deployment. It also has an automated issue tracking
system that can help issue reporting at each stage of continuous development and deployment, which
enables seamless tracking for continuous delivery that meets the defined quality standards.
Manage and Secure
As part of manage, we handle various phases of the program, and as part of security, we manage the overall
security of the solution.

4. We have depicted various GitLab tools across various solution pillars needed for a full-fledged DevOps
implementation. For each solution pillar, GitLab has various corresponding tools that help meet the devops
needs. The Kubernetes and docker-based solution is purely the next gen solution for a Devops platform.
It has a sophisticated mechanism for stakeholders and users such as project management, development team,
quality assurance team, devops engineers and business users, enabled with a rich user interface and visual
dashboards for metrics. This enables effective collaboration from all participating teams in all roles and
responsibilities.
For the compliance needs, Static Application Security Testing (SAST), Dynamic Application Security Testing
(DAST), license management, dependency check and container scanning tools take care of quality standards,
and automated checks makes continuous delivery adhere to quality profiles.
Let us check the GitLab devops setup and configuration process to follow for dependencies that need to be
identified for a program that has both cloud and mobile apps deployment.
Given below are the Prerequisites for GitLab devops setup,
1. Enterprise subscription
2. Creation of a software repository
3. Repo workflow
4. Branching strategy
5. Environment strategy
6. GitLab pipeline strategy
7. Tools consideration in each GitLab pipeline stages
8. Quality profiles and gates for each stage or overall pipeline
9. Build deployment and distribution strategy
10. App promotion strategy
Tools and strategy consideration for GitLab DevOps
Design
Given below are the main design considerations:
• Single eco system for end-to-end devops
• Managed SaaS-based solution for DevOps
• Easy to configure and scalable DevOps for a large-scale program with a multi-pod-based diverse
technology stack
• Industry standard security, manage and monitor mechanism
• Continuous delivery that suits the agile methodology-based project
Drivers
• Git way of working for developers, devops and release managers
• Optimized infrastructure maintenance
• Steps and stage-wise configuration with automated issue tracking, quality gates for standard and security
scans for compliance
5. Motivations
• Automated devops system that lets everyone in the team to contribute, brings in collaboration, enables
remote monitoring and performs automated issue reporting and tracking for a continuous delivery
• Keeps system as well as source code secured and compliant with security standards and quality gates
We have depicted a sample GitLab based DevOps in Figure 3
Branching Strategy
Designing and implementing appropriate branches is crucial to implement an extensible development and
deployment strategy. In this section, we have laid out a few GitHub-based branching best practices.
To start with, we need to define the core branches based on the development and deployment needs. In
Figure 4, we have defined the branching strategy that we commonly use.

Release

Feature
Each solution component will have its own independent Github repository
6. The main branches are as follows:
• Feature branch is used for user story/feature development
• Dev branch is used for Dev environment
• Release branch is used for stable releases
• Master branch represents what’s in production currently or is production-ready.
In Figure 5, we have depicted the process of a release across all these branches.
Given below are the high level steps in the release management flow:
1. User stories are developed in separate Feature branches and merged back into the Dev branch
2. Dev branch allows bug-fixing, hardening and other release preparation to continue in isolation. No feature
development should happen on these branches.
3. Dev branch will be protected so that code in feature branches can be reviewed and approved by designated
reviewers before merging into release branch. This can be implemented using built-in Pull request and
protection features of GitHub.
4. QA-approved build version gets deployed to UAT and other pre-production environments. If there are any
defects, it will be done from the Dev branch.
5. Once the code is stable enough for release, it will be pushed to the Release branch. The code in this branch
is tagged with the release number.
6. The code from Release branch will be pushed to the Master branch for production deployment.
At a high level, the flow will be like this:
Feature Branch Dev Branch Release Branch
To handle the production bug fixes, we use a hotfix branch as depicted in Figure 6. A branch will be created as
needed for hotfixes in production. These will originate from the master branch and merged back into master
as well as the dev branch for inclusion in future releases. Hotfix branches should be very short-lived.

7. DevOps Implementation
The start of the pipeline is based on the code commit, which can either be automated or set for manual
execution. Each of these start a stage that can either have a single or multiple jobs with an objective that
decides if the stage has been successfully completed. Quality gates can be defined for each stage to manage
the quality levels.
Build
It is a build phase to generate the binary files in either debug or release mode. The GitLab pipeline .yml file
will have the package manager dependency such as Maven, NPM, Pega, to compile the binary using gradle,
npm etc.
Test and Code coverage
Unit test cases and fast fail test cases can be configured here to identify the code quality. Additionally, UI
automation test cases can also be executed in this phase. The end objective of this phase is to identify the
code coverage in terms of percentage through these test cases.
Code correction
Code analyzer and lint tools perform code correction checks and report identified issues in this stage.
Code analysis
SonarScanner or SonarQube-based code analysis is performed in this stage. This stage can also be configured
to consolidated issues identified by the code correction phase, so that all issues are available from a single
SonarQube dashboard.Quality gate rules can be defined at this stage before a final artifact is generated such
that only if the rules are passed, the pipeline proceeds to the next stage.

8. Artifact generation and signing
Artifact generation is a phase where a final distributable binary is created that also includes signing the
artifact to make it secure and ensure that code obfuscation is achieved.
Dependency scanning
Dependency scanning helps determine if the external code integrated in the binary such as plugins, sdks,
frameworks, library contains any vulnerabilities.
License management
As part of this phase, we attribute all the licensed software used in the application along with their licenses.
Artifact Upload
At this stage of a pipeline, the artifacts upload to perform a deployment to external systems such as App
store / Play store for mobile apps or multi-cloud-based environment for specific deployment of web apps so
that the backend solution can be enabled. A successful deployment means a successful pass of all quality
gates set for previous stages of pipeline, thus assuring compliance to security and quality standards.
