  • A Closer Look at Azure DevOps

    A Closer Look at Azure DevOps

    Microsoft’s Azure DevOps Server is emerging as one of the most popular cloud application development environments. Like most continuous integration/continuous delivery (CI/CD) platforms, it provides features such as version control, reporting, project management, automated builds, and testing. It covers all aspects of the application life cycle and enables DevOps. Here’s a closer look at this cloud computing environment.

    Azure DevOps provides a number of different developer services that allow DevOps teams to plan work, collaborate on code development and build and deploy applications. It is highly collaborative and brings together developers, project managers and individual contributors to develop software. It allows organizations to create and improve products much faster than with traditional software development approaches.

    Services or Server?

    Teams can work in the cloud using Azure DevOps Services or on-premises using Azure DevOps Server.

    The cloud offering, Azure DevOps Services, is a scalable, reliable and globally available hosted service. It’s backed by a 99.9% SLA, is monitored by Microsoft’s 24/7 operations team and is available in local data centers around the world.

    The on-premises offering, Azure DevOps Server, is built on a SQL Server back end. The on-premises version is preferable when organizations need their data to stay within their network or when they want access to SQL Server reporting services that integrate with Azure DevOps Server data and tools.

    Although both offerings provide the same essential services, Azure DevOps Services offers some added benefits:

    • Simplified server management.
    • Immediate access to the new features and updates.
    • Improved connectivity with remote sites.
    • A transition from capital expenditures (servers, etc.) to operational expenditures (subscriptions).

    There are also some other key differences depending on your organization’s or your team’s needs. These can also be helpful if you’re migrating from on-premises to the cloud:

    Differences in Specific Feature Areas

    Although Azure DevOps Services is a hosted version of Azure DevOps Server, there are some feature differences. Some Server features aren’t supported in Services; for example, Azure DevOps Services doesn’t integrate with SQL Server Analysis Services to support reporting. Process customization and reporting also differ in their support.

    Integrated Features

    Azure DevOps provides integrated features that can be accessed through a web browser or an IDE client. One or more of the following standalone services can be used based on your organization’s business needs:

    • Azure Repos: Azure repos provides Git repositories or Team Foundation Version Control (TFVC) for source control.
    • Azure Pipelines: This service provides build and release services to support continuous integration and continuous delivery of applications.
    • Azure Boards: This suite of Agile tools supports planning and tracking work, code defects and issues using Kanban and Scrum methods.
    • Azure Test Plans: Azure Test Plans provides several tools to test applications, including manual/exploratory testing and continuous testing.
    • Azure Artifacts: These allow teams to share packages such as Maven, npm, NuGet and more from both public and private sources and integrate package sharing into pipelines.

    Use of the following collaboration tools is also supported:

    • Customizable team dashboards with configurable widgets to share information, progress and trends.
    • Built-in wikis for sharing information.
    • Configurable notifications.

    Azure DevOps supports adding extensions and integrating with other popular services, such as Campfire, Slack, Trello, UserVoice and more. In addition, DevOps teams can also develop their own custom extensions.

    Azure DevOps Services supports integration with GitHub and GitHub Enterprise Server code repositories. Azure DevOps Server supports integration with GitHub Enterprise Server repositories.

    Getting Started

    When you sign up for Azure DevOps, you must first register an organization, project and version control type. DevOps teams can create multiple projects and differentiate them with separate names and access permissions. Projects can be set to public or private. Teams can also use Azure Boards for collaboration and project management, and can also configure use of Agile practices. After setting up your team, you can use the platform to begin deploying your applications to Azure.

    In addition to a collaborative environment, Azure DevOps provides access to an Azure Pipeline service that supports multiple languages and platforms. The Azure DevOps pipeline is a set of services that are grouped into individual projects. 

    Additionally, Azure Test Plans feature facilitates automated testing. It is also possible to set up deployment pipelines with different components for multiple applications. 

    Azure Pipeline can track work status, manage backlogs and create custom reports. With the help of the Azure DevOps pipeline, developers can create, manage and deploy their projects in a single environment. With this solution, DevOps teams will have a single point of contact and can communicate with each other.

  • What is DevSecOps?

    What is DevSecOps?

    While traditional development practices have long separated security and compliance, DevSecOps as a series of best practices integrates security into every phase of the DevOps software development life cycle. DevSecOps introduces and automates security in the earlier phases of the software development life cycle rather than bolting it on at the end. The approach saves money, saves time on tedious manual tasks, helps organizations meet regulatory compliance requirements and significantly reduces the risk of critical security bugs being found after an application’s final build. DevSecOps promotes the use of, for example, active penetration testing, security audits and other security tools within an agile development process.

    The goal of DevSecOps is to create a collaborative environment between developers and security professionals that enables organizations to build secure code faster and more easily. By emphasizing security from the very beginning of the process, it becomes a priority in the app dev process rather than an afterthought. Over time, developers become more familiar with the common weaknesses in software that today result in more insecure applications being deployed than most anyone really wants to admit. The end goal is to create secure applications by making it easier for developers, security experts and operations professionals to collaborate throughout every stage of application development.

    Minimizing Application Vulnerabilities

    It may seem tedious and expensive to integrate security into the development process, but it’s become essential for organizations to embrace DevSecOps to minimize the number of application vulnerabilities that cybercriminals might exploit. When applied throughout the development process, scanning and reporting can take place within a matter of minutes rather than holding up deployment at the end of the process to review the entirety of an application.

    Leaving security to either the end of the application development process or, worse yet, after an application has been deployed only increases the total cost of ownership. It’s much more expensive to remediate a vulnerability after an application has been deployed than it is to address an issue during the application development process.

    Implementing DevSecOps requires organizations to set up workflows that are managed via a continuous integration/continuous delivery (CI/CD) platform. Most critically, developers must understand the role security plays in enabling organizations to identify vulnerabilities as early as possible in the application development life cycle.

    Inserting security audits and penetration testing into the development process, for example, helps ensure the security of an application. When changes are made in a project, scanning, architecture reviews and penetration testing can be triggered within the development flow to save time and resources.

    DevSecOps Adoption

    However, there are many technical and cultural challenges ranging from tool integration to a lack of trust between developers and security teams that can impede the adoption of DevSecOps. Security professionals are tasked with identifying and preventing vulnerabilities in applications. Acceptance test criteria, user designs and threat models should be created by security professionals. The development team then needs to define a code review system to ensure uniformity.

    Despite those concerns, the most important thing is to simply get started. Ideally, development and security teams should work together to create a safe application development and software development environment. There is no need to create separate teams or apply different policies.

    The biggest benefit of DevSecOps is that it eliminates silos between development and operations. As a result, software engineers integrate cybersecurity processes from the start of the development process. This includes ensuring that every component, configuration item, and installation process is securely patched and documented. This concept of shifting security to the left allows the security team to identify and remediate security threats early on.

    In the longer term, however, adopting DevSecOps best practices will ensure security remains a top priority in the wake of a series of high-profile cybersecurity breaches. In short, there is now more focus on DevSecOps with the goal of securing software supply chains.
