How Can You Enable Communication Between Members Of The Development Team Working In Different Locations Around The World Using Azure Devops

For such an application, the isolation of members of different project teams into different communication channels is the first criterion. Additionally, maintaining communication history in the concerned channels is necessary. Effective integration with Azure DevOps is also important for the application and allows one to add external suppliers and contractors to projects. The Microsoft teams have addressed these requirements through their offering of the right capabilities.

Classifying teams allows the creation of different channels by users for the organization of communications according to the topic. Every channel can include a few to thousands of users.

Microsoft Teams provides a guest access feature that allows the invitation of external people to join internal channels for the purpose of meetings, file sharing, and messaging. It helps in B2B project management and can also directly integrate with Azure DevOps.

Q21 How Can I Set Deployment Order For Applications

WebLogic Server 8.1 allows you to select the load order for applications. See the Application MBean Load Order attribute in Application. WebLogic Server deploys server-level resources before deploying applications. Applications are deployed in this order: connectors, then EJBs, then Web Applications. If the application is an EAR, the individual components are loaded in the order in which they are declared in the application.xml deployment descriptor.

What Is The Main Difference Between Bdd And Tdd

If TDD is about designing a thing right, Behavior-Driven Development is about designing the right thing. Like TDD, BDD starts with a test, but the key difference is that tests in BDD are scenarios describing how a system responds to user interaction.

While writing a BDD test, developers and testers are not interested in the technical details , rather in behavior . BDD tests are used to test and discover the features that bring the most value to users.

How Is Devops Different From Agile Methodology

DevOps is a culture that allows the development and the operations team to work together. This results in continuous development, testing, integration, deployment, and monitoring of the software throughout the lifecycle.

Agile is a software development methodology that focuses on iterative, incremental, small, and rapid releases of software, along with customer feedback. It addresses gaps and conflicts between the customer and developers.

DevOps addresses gaps and conflicts between the Developers and IT Operations.

What Do You Mean By Continuous Integration

Presently, developing teams often work on different segments on similar web applications to boost efficiency, reliability and to cut down the errors. The integration tests are exactly what they need to be performed and for this, integration of all the modules is necessary. An automated process is considered for such an approach that basically verifies all the code. This simply lets everything tested in a serial manner and that is why we called it Continuous Integration.

What Is The Key Features Of Git That Makes It More Efficient Compared To Other Version Control Systems Such As Svn And Cvs

Distributed: Git is a distributed version control system. Git has a central server which maintains the project file and its history, called as a repository. Each user of Git has a complete and independent copy of this repository on his own local machine. Hence, Git users can continue working with Git and refer to history even if the central repository is unavailable.

Like Git, alternative source control systems such as SVN and CVS also have a central server which maintains the project files and its history. But unlike Git, users of these version control system do not have a local copy of the project files and its history. Hence these users are dependent on the central system, and cannot continue to work with the version control system if the central server becomes unavailable for any reason.

Snapshot-based: Git is a snapshot-based version control system. Every time a user commits the project, Git takes a snapshot of the project files and changes at that moment and stores a reference to that snapshot. If a file has not changed, Git links to the previous file instead of storing the file again.

Alternative version control systems such as SVN and CVS are delta-based version control systems. These systems store the project files and changes made to each file over time.

Integrity: Every file in Git is checksummed using a SHA-1 hash before it is stored, and is referred to with that checksum. This makes it impossible to lose or corrupt the files without Git detecting it.

Q21 How Do I Move Jenkins From One Server To Another

Ans: There are multiple ways to do that as mentioned below:

• Move a job from one installation of Jenkins to another by simply copying the corresponding job directory.

• Make a copy of an existing job by making a clone of a job directory by a different name.

• Rename an existing job by renaming a directory.

• Enter the project name and, from the options, select ‘Multibranch pipeline’

• Then select the repository location, branch source , and add the branch source credentials.
• Save the project
• Now, Jenkins automatically creates new Multibranch Pipelines for repositories
• Then to connect to the GitHub repo, we need the HookURL
• To get this URL from the repository settings, add this HookURL to the Webhooks section
• Once the jobs are created, Jenkins will automatically trigger the build

Explain The Architecture Of Docker

Q2 What Is The Need For Devops

According to me, this answer should start by explaining the general market trend. Instead of releasing big sets of features, companies are trying to see if small features can be transported to their customers through a series of release trains. This has many advantages like quick feedback from customers, better quality of software etc. which in turn leads to high customer satisfaction. To achieve this, companies are required to:

DevOps fulfills all these requirements and helps in achieving seamless software delivery. You can give examples of companies like Etsy, Google and Amazon which have adopted DevOps to achieve levels of performance that were unthinkable even five years ago. They are doing tens, hundreds or even thousands of code deployments per day while delivering world-class stability, reliability and security.

If I have to test your knowledge on DevOps, you should know the difference between Agile and DevOps. The next question is directed towards that.

Q4 Explain The Different Phases Of The Devops Lifecycle

Azure DevOps interview questions cover every phase of the DevOps lifecycle separately or in a single question. The different phases in the DevOps methodology are:

• Plan â The team discusses all the project requirements, like time for each stage, cost, and more.
• Code â The software engineers write the small codes, known as units, according to the client’s requirements.
• Build â Involves the building of the units.
• Test â The team tests if there are any mistakes. If yes, it is returned for a rebuild.
• Integrate â Involves the integration of all the units of the codes.
• Deploy â codeDevOpsNow is deployed on the client’s environment.
• Operate â Operations are performed on the code.
• Monitor â This is the last phase wherein applications are monitored in the client’s environment.

How Multiple Jobs Can Be Created From A Single Job In Bamboo

It is basically a simple approach. For this, the list of tasks can be divided into simpler and well-defined jobs. It is necessary to make sure that every task or job must be accomplished before the next job is considered. This is necessary because many times it has been observed that a stage or a job depends on some or one previous job. If the same is not completed, there are errors in the next and you need to waste the time locating them. The problem in one job means problems in all others due to the same reason and i.e. their dependency on others.
