Yea, it's exactly like MongoDB which is also AGPL.

Using the database doesn't impose any restrictions on your software.

Even hacking on juju to add API'S you for your client software doesn't impose restrictions on the client -- it just means you are subject to the AGPL licence source distribution rules on the patched version of Juju.

Mongo is a different beast, because the mongo client has a GPL exception which allows your code, that is linked to the mongo client, to use a different license. This is a friendly exception, that the mongo developers allowed. Without that exception everything using mongo even over the Internet would automatically also be AGPL licensed.
