The Azure  DevOps Project simplifies the process of bringing existing code and Git repositories to Azure for the creation of CI and CD pipelines.
Now let’s move on to the advanced Azure DevOps Interview Questions for seasoned professionals.

Containers allow you to bundle together software code, configurations, dependencies, and packages into a single unit or object. Multiple containers can run on the same machine and share the same operating system, allowing for fast, reliable, and consistent deployments anywhere.

This is a straightforward Azure DevOps interview question, but it can be challenging to respond to. Azure Repos is a version control system for managing the various versions of a code as well as the code itself throughout the development lifecycle. It’s simple to keep track of any code changes made by different teams. It also keeps a detailed record of these changes and their history in order to improve team coordination. At a later stage, the changes are merged.

The following containers are supported by Azure Development and operation(DevOps):
• Azure Kubernetes services 
• Docker
• Containers in Asp.Net
• Azure Service Fabric app with Docker integration

Azure Pipeline develops and tests code projects automatically. It’s an Azure cloud service that works with a wide range of project types and languages. This service aids in making code projects more accessible to other users.

In DevOps, Selenium is used for continuous testing. It specialises in regression and functional testing in various forms.

Azure DevOps offers a service called Azure Test Plans. It includes a browser-based test management solution as well as critical user acceptance testing, exploratory testing, and planned manual testing capabilities. It also comes with a browser extension that allows for exploratory testing and stakeholder feedback.
Exploratory and manual testing are important methods for assessing the quality of a product or service.

Azure Boards is a service provided by Azure DevOps. It aids in the management of work in software projects and offers a variety of functionalities such as native support for Kanban and Scrum, customizable dashboards, and integrated reporting. Boards, sprints, work items, dashboards, backlogs, queries, and other features are available in Azure Boards.

One of the more difficult Azure DevOps interview questions. Azure DevOps Services is a Microsoft Azure cloud service that provides a highly scalable and reliable hosted service that is globally available. DevOps Server, on the other hand, is an on-premise solution with a SQL Server back end.
When enterprises want to keep their day within their network or when they need access to SQL Server reporting services that are integrated with Azure DevOps data and tools, they choose the on-premise offering.

Multiple tools and technologies can be used in conjunction with Azure to create solution architectures for the following DevOps scenarios:
• Continuous Integration/Continuous Delivery for Azure VMs 
• Continuous Integration/Continuous Delivery for Azure Web Apps 
• Continuous Integration/Continuous Delivery for Azure VMs 
• Using Azure Web Apps and Jenkins for Java CI/CD 
• Using Jenkins and Terraform for immutable infrastructure on Azure Virtual Architecture 
• Container CI/CD with Jenkins and Kubernetes on Azure Kubernetes Service

Azure pipelines exist to ensure a secure, simple, and quick way to automate project development processes as well as their availability. They are completely free to use in public projects and reasonably priced in private ones (free 30 hours per month).
Here are a few reasons why you should use CI/CD and Azure pipelines:
• Supports any platform or language 
• Allows collaboration with open-source projects>
• Development on Windows, Mac, and Linux machines
• Allows for simultaneous deployment to multiple types of targets 
• Integrates with GitHub and Azure deployments

Here are a few Jenkins plugins that you might find useful:
• Maven 2 project 
• HTML publisher 
• Amazon EC2 
• Join 
• Copy artefact 
• Green Balls

Yes, it’s conceivable. Jenkins is portable, meaning it can be moved or copied from one server to another. It is possible to move the jobs directory from the older server to the new or current one when copying Jenkins. This allows you to move an installation by copying it into the appropriate job directory.

The dogpile effect, also known as a cache stampede, occurs when a cache expires and the website is bombarded with multiple requests at the same time. By generating a new value as the cache expires, the semaphore lock helps to prevent this effect.

Memcached has a number of features, including: 
• CAS Tokens 
• Callbacks 
• GetDelayed 
• Binary protocol 
• Igbinary
