Service aliases can be considered as mappings of services. Accessing a service alias is equivalent to accessing the service itself, allowing multiple service aliases to point to a single service. Service aliases are primarily applicable in the following scenarios:
If you do not want to use the service name as the polarismesh service name—for example, if you want the polarismesh service name to be in uppercase while Kubernetes service names are restricted to lowercase—you can use the alias annotation to specify an uppercase polarismesh service name.
You want to expose a service in a namespace to another namespace. In this case, you can use a service alias to specify another namespace.
Different application names are required to provide services to different external clients, but the actual backend service is the same.
