What is Azure DevOps?

DevOps is a combination of both development (Dev) and operations (Ops) practices that bring in people, processes, and technology together to continuously provide value to the organizations in their endeavor to make their business processes faster and more efficient.

What is release in Azure?

A release is a construct that holds a versioned set of artifacts specified in a CI/CD pipeline. It includes a snapshot of all the information required to carry out all the tasks and actions in the release pipeline, such as stages, tasks, policies such as triggers and approvers, and deployment options. There can be multiple releases from one release pipeline, and information about each one is stored and displayed in Azure Pipelines for the specified retention period.

What is deployment in Azure pipeline?

A deployment is the action of running the tasks for one stage, which can include running automated tests, deploying build artifacts, and whatever other actions are specified for that stage. Initiating a release starts each deployment based on the settings and policies defined in the original release pipeline. There can be multiple deployments of each release even for one stage. When a deployment of a release fails for a stage, you can redeploy the same release to that stage. To redeploy a release, simply navigate to the release you want to deploy and select deploy.

What are processes in DevOps?

The DevOps process flow is all about agility and automation. Each phase in the DevOps lifecycle focuses on closing the loop between development and operations and driving production through continuous development, integration, testing, monitoring and feedback, delivery, and deployment.

What are the 5 main phases in the DevOps lifecycle?

Various phases such as continuous development, continuous integration, continuous testing, continuous deployment, and continuous monitoring constitute DevOps Life cycle.

How many steps are in DevOps?

The DevOps pipeline typically has eight stages. In the Development phase, they are: plan, code, build, and test. In the Operations phase, the stages are: release, deploy, operate, and monitor.

Is DevOps under cloud?

DevOps is a software engineering practice that is suited to cloud computing. In a DevOps environment, developers collaborate with IT operations and other teams. DevOps goes beyond continuous integration and continuous delivery (CI/CD) to enable near-instantaneous deployment of products and services in the cloud.

What are the DevOps principles?

1) Automation: Automate everything, such as workflows, testing new code, and how your infrastructure is provisioned to cut down on waste and overwork. 2) Iteration: Write small chunks of code during a time-box sprint to support releases and sub-releases that increases the speed and frequency of deployments. 3) Continuous improvement: Continuously test, learn from failures, and act on feedback in order to optimize performance, cost, and time to deployment. 4) Collaboration: Unite teams, foster communication and breakdown silos between development, IT operations, and quality assurance.

What are the Benefits of DevOps?

.Faster time to market .Higher ROI .Greater user/customer satisfaction .Increased efficiency .Improved collaboration .Early detection and correction of issues As teams work together seamlessly, supported by both process and culture, one of the many benefits of DevOps include greatly reduced risk of miscommunication or misalignment. Clear communication results in increased efficiency and ultimately higher quality products. Additionally, agile practices, such as continuous integration and deployment, combined with automated testing and regular feedback both accelerate the development process and ensure that bugs or other issues are detected and managed early.

What are the Benefits of migrating to the cloud?

The ultimate goal of any cloud migration is to host applications and data in the most effective way, based on cost, performance, and security. The cloud offers a number of advantages and solutions for digitally-minded organizations including: Greater flexibility Scalability Elasticity Tighter security Reduced costs

What is PaaS (Platform-as-a-Service)?

PaaS, or Platform-as-a-Service, is a cloud computing model that provides customers a complete cloud platform—hardware, software, and infrastructure—for developing, running, and managing applications without the cost, complexity, and inflexibility that often comes with building and maintaining that platform on-premises. It is a cloud computing platform designed to enable organizations to deploy, provision and run applications without needing to build out the underlying infrastructure. In essence, the cloud provider delivers the infrastructure, while the organization either provides its own application or uses an application that has been made available by the cloud provider. Every leading cloud service provider—including Amazon Web Services (AWS), Google Cloud, IBM Cloud and Microsoft Azure—has its own PaaS offering. Popular PaaS solutions are also available as open source projects (e.g. Apache Stratos, Cloud Foundry) or from software ventors (e.g. Red Hat OpenShift and Salesforce Heroku).

What is IaaS (Infrastructure-as-a-Service)?

Infrastructure-as-a-Service, commonly referred to as simply “IaaS,” is a form of cloud computing that delivers fundamental compute, network, and storage resources to consumers on-demand, over the internet, and on a pay-as-you-go basis. IaaS enables end users to scale and shrink resources on an as-needed basis, reducing the need for high, up-front capital expenditures or unnecessary “owned” infrastructure, especially in the case of “spiky” workloads. In contrast to PaaS and SaaS (even newer computing models like containers and serverless), IaaS provides the lowest-level control of resources in the cloud. Amazon Web Services (AWS) Amazon is one of the most popular eCommerce stores today. ... Microsoft Azure. Azure is another cloud-computing industry giant. ... Alibaba Cloud. Alibaba Cloud, also known as AliYun, is a Chinese IaaS provider. ... Google Cloud Platform.

What is SaaS (Software-as-a-Service)?

Software as a service (SaaS) allows users to connect to and use cloud-based apps over the Internet. Common examples are email, calendaring, Zoom, DropBox, Github, Doc Sign, Adobe, Oracle and office tools (such as Microsoft Office 365). SaaS provides a complete software solution that you purchase on a pay-as-you-go basis from a cloud service provider.
