What is DevOps?

DevOps is a union of people, process and technology products which covers Continuous Integration (CI), Continuous Delivery, Continuous Deployment (CD), Continuous Testing and Project Management.

It is an approach which simplifies the software application delivery and working structure, thereby improving quality and enabling faster delivery and also value to end users by maintaining both functionality and end-user experience.

What is difference between Azure and Azure Devops?

Azure and Azure DevOps are two different things. Azure is a Microsoft cloud computing platform that offers a wide range of services, including compute, storage, networking, databases, and machine learning.

Where as Azure DevOps is also owned by Microsoft. It is a suite of tools and services that helps for the software development lifecycle. Azure DevOps offers features like Continuous integration and continuous delivery (CI/CD), project management, test management, artifact repository. Azure DevOps tools can be used with any cloud platform.

What is Azure DevOps?

Azure DevOps is a collection of services provided by Microsoft to support the end-to-end development lifecycle. It includes services for:

  • Version control (Azure Repos)
  • Reporting (Azure Boards)
  • Requirements management (Azure Artifacts)
  • Project management (Azure Boards)
  • Automated builds (Azure Pipelines)
  • Lab management (Azure Test Plans)
  • Testing (Azure Test Plans)
  • Release management (Azure Pipelines)

With Azure DevOps, developers can use a single platform to plan, develop, test, and deploy their applications. These services can be used together or individually, and integrate with a wide range of tools and frameworks.

Azure DevOps is a cloud-based service, which means that all data and services are stored on Microsoft’s servers and can be accessed from anywhere with an internet connection.

What is Azure DevOps Services?

Azure DevOps Services is a collection of services provided by Microsoft that allows for the management of the entire software development lifecycle. It includes tools for agile planning, source control, continuous integration and continuous delivery, and testing.

It also provides a central location for collaboration and communication among developers, stakeholders, and customers. Additionally, it has a built-in integration with Azure, which allows for easy deployment of applications to the cloud.

Note: Azure DevOps Services was formerly known as visual studio team services (VSTS).

Where to Access Azure DevOps services?

One can access Azure DevOps services through dev.azure.com

What is Azure DevOps Server?

Azure DevOps Server is a Microsoft product that provides version control, reporting, requirements management, project management, automated builds, lab management, testing, and release management capabilities. It is the on-premises version of Azure DevOps, and allows organizations to run these services on their own servers, rather than using the cloud-based Azure DevOps services.

Note: Azure DevOps Server was formerly known as team foundation server (TFS).

What is TFS in Azure DevOps?

Team Foundation Server (TFS) is the previous version of Azure DevOps Server. It is a Microsoft product that provides version control, reporting, requirements management, project management, automated builds, lab management, testing, and release management capabilities.

TFS was available as an on-premises product, which allowed organizations to run these services on their own servers, rather than using the cloud-based Azure DevOps services.

In 2018, Microsoft rebranded TFS as Azure DevOps Server, and made it available as an Azure DevOps Server on-premises deployment option. The main difference between TFS and Azure DevOps Server is the name and branding, and the Azure DevOps Server provides more capabilities and integrations than TFS.

Is Azure DevOps Server Free?

Azure DevOps Server is not free. It is a paid product, with pricing based on the number of users and the level of access they need. However, Microsoft does offer a free version of its DevOps services, called Azure DevOps Services, which includes many of the same features as the server version.

What are the Benefits of using Azure DevOps?

Here are some important benefits of using Azure DevOps or Azure DevOps Server:

  1. Increased efficiency: Azure DevOps can help teams to automate tasks, which can save time and improve productivity.
  2. Improved quality: Azure DevOps can help teams to improve the quality of their software by providing features such as automated testing and continuous integration.
  3. Increased collaboration: Azure DevOps can help teams to collaborate more effectively by providing a central place to store code, track work, and communicate with each other.
  4. Reduced risk: Azure DevOps can help teams to reduce the risk of errors and defects by providing features such as version control and automated testing.

What is service connection in Azure DevOps?

In Azure DevOps, a service connection is a secure and authenticated link between Azure DevOps and an external service or resource. Service connections act as bridges between Azure DevOps and external systems, such as Azure subscriptions, GitHub repositories, or container registries.

User needs to provide the necessary credentials and configuration details required for Azure DevOps to establish a connection and communicate with the external service.

What is the use of pipeline in Azure DevOps?

Azure pipelines allows users to automate the process of software development and operations together to run Continuous Integration or Continuous Delivery (CI/CD) pipelines.

What is the use of build pipeline in Azure DevOps?

Azure DevOps build pipeline is the automated system used for continuous integration. Like Build Code, Create Packages and Run Code.

What DevOps practice does Azure Application Insights support?

Azure Application Insights is a comprehensive service provided by Azure, offering a range of powerful tools for monitoring, data collection, and analysis of application health and performance metrics. With its focus on Continuous Monitoring, Azure Application Insights is a valuable asset for DevOps practices.

By leveraging this service, organizations can ensure seamless monitoring and gain insights into their applications, enabling them to make informed decisions and optimize performance.
