VSTS ( Visual Studio Team Services ) Interview Questions for Experienced/VSTS Interview Questions and Answers for Freshers & Experienced

What are the necessary components for the integration of Azure DevOps and Bitbucket?

The integration of Azure DevOps and Bitbuckets requires a self-hosted agent and an external Git service connection. Since GitLab CI/CD is compatible with GitHub and Bitbucket. Instead of moving an entire project to GitLab, it is possible to connect the external repository. One can make use of GitLab CI/CD in this manner.

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.

When you undergo devops training, you can get familiar with different phases in DevOps. The different phases available in the DevOps lifecycle are as below:

Plan: Firstly, there must be a plan for the type of application required to be developed. It is always a decent idea to get a rough picture of the development process.

Code: The application is coded according to the end-user requirements.

Build: It involves building the application by assimilating different codes created in the previous steps.

Test: Recognized as the most vital step of the application development, it involves testing the application and rebuilding, if necessary.

Integrate: Several codes from different programmers are combined into one.

Deploy: The code is deployed in a cloud environment for future usage. Any new modifications do not influence the overall functioning of a high-traffic website.

Operate: Operations are carried out on the code if needed.

Monitor: The performance of the application is monitored. Modifications are done to fulfill the end-user requirements.
