One of the main reasons why mobile app deployment is so challenging is because the entire procedure is disjoint. It needs proper coordination of internal resources across different systems and teams. Some aspects of the deployment process are almost completely automated while some areas are completely manual. As a result, there is a lot that needs to be done in order to successfully complete the process of app deployment.
Another challenge with mobile app deployment is that it is quite easy for attackers to infiltrate the system if the app is poorly written or not properly secured. Because most mobile apps are short codes, they have to be written to very tiny formats that can easily be manipulated by attackers. Once the code is infected, it cannot be uninstalled unless the application is deleted from the system. Moreover, the infected code will most likely remain active on the device as attackers have access to every app installed on a phone.
Many companies prefer using custom software for app deployment because they can specify rules for how each resource should behave and which resource should be deployed on which devices. Another great thing about using custom software for app deployment is that it enables companies to make the devices behave according to their specific needs. For example, if a company wants to test a new email client on a device that is used for social media, it can be easily implemented. On the other hand, if a company wants to use device security features, it can be disabled.
