Managed Google Play is a private version of the Google Play Store designed for large organizations to manage and deploy applications and updates to Android device fleets. It offers security, scalability, and deployment capabilities, but its features are limited compared to other solutions like Esper's app deployment solution. Managed Google Play is best suited for general-purpose devices with lots of apps, whereas enterprises with dedicated device environments may find it insufficient due to limitations in testing and deployment granularity. Esper's solution provides more granular control over fleet software deployments through code-driven extensibility, making it a better option for organizations with unique requirements.
