    11  # Update Strategies
    12  
    13  Most applications are long-lived and require updates over time. Whether you are
    14  deploying a new version of your web application or upgrading to a new version of
    15  Redis, Nomad has built-in support for rolling, blue/green, and canary updates.
    16  When a job specifies a rolling update, Nomad uses task state and health check
    17  information in order to detect allocation health and minimize or eliminate
    18  downtime. This section and subsections will explore how to do so safely with
    19  Nomad.
