Is the need for security defined for each function?
Precisions
The security needs are different depending on the clients and the hosted services. The same generic rule of excellence in this area is not always necessary. The design of high availability mechanisms, which involves many redundant components, should be able to adapt to real needs in order to reduce the impact of the services.
