   DevOps - automation
   Release Management (Azure DevOps)
   • End-2-End Management (backlog, build,
   test, release)
   • History
   • Approval Workflows
   • Different Phases
   Release Management is a service in Visual Studio Team Services (VSTS)
   and Team Foundation Server (TFS 2015.2 and later) and an essential
   element of DevOps CI/CD that helps us to continuously deliver software
   to our customers at a faster pace and with lower risk. We deliver our
   software in multiple environments all the way to production, with semi-
   automated processes with approvals and on-demand deployments.

    Diverse Teams are Smarter
    In a nutshell, enriching your employee pool with representatives of different genders,
    races, and nationalities is key for boosting your company’s joint intellectual potential.
    Creating a more diverse workplace will help to keep your team members’ biases in check
    and make them question their assumptions.

    • They focus more on facts
    • They process those facts more carefully
    • They’re also more innovative

    What’s it all about
    Always be open and eager to learn. The
    world is changing, especially in technology,
    and we will always need to keep up. In
    addition to technology, seek to learn and
    understand from those who are different
    from you. DevOps is, at its heart, a cultural
    movement, wherein groups with
    traditionally very different goals come
    together to learn from one another with
    empathy. We do better when we hear from
    those with diverse backgrounds and
    viewpoints and voices. Remember: we are
    building tech for the world. The world is
    made up of many people with varied
    experiences.
