applications. After PAM is used, the application can be completed by PAM without integrating the verification function. For example, in Linux, the Login service provides the system logon service for users. It prompts the user to enter the corresponding user name and password to verify the user's validity. When PAM is used, this verification process can be replaced by PAM. PAM has great flexibility, and the system administrator can use it to freely se

Imagine if we were going to build a mobile app , and not enough budget to buy hardware and software resources, what to do? For example, if we are going to run this appon our existing infrastructure, but we have only a few old low-performance machines on hand, what is the way to deploy and run mobile apps? For some companies, their application itself is not a lot of users, fixed users about hundreds of people. In this case, spending a lot of money to buy resources is certainly not cost-effective
