Are server and Instance the same ?

  • A sql server and a instance are the same?

  • No. They are different. A server can host one default instance and/or many named instances. A default instance has no instance name and can be accessed without providing a port number or instance name.

    Some examples of ways to access a SQL Server instance...there are many more but you get the idea:

    Access the local default instance:

    .

    Access the local default instance:

    SERVER_NAME

    Access a named instance:

    SERVER_NAME\INSTANCE_NAME

    Access an instance by server name by its dedicated port number:

    SERVER_NAME,PORT_NUMBER

    Access a local instance by its dedicated port number:

    .,PORT_NUMBER

    Access a default instance by IP address:

    IP_ADDRESS
