rohit, i asked this question because requests from domain admins are usually from outside of datacenter for a public cloud.
so artifact built from user package can be directly deployed as a user api server and serve user requests. but to serve domain admin request, sysadmin has to prepare another api server with another set of apis, which is a sub set of admin package, is this correct? sent from phone, sorry for typos. mice 在 2012年12月7日星期五，Rohit Yadav <[email protected]> 写道： > > On 06-Dec-2012, at 4:29 PM, Mice Xia <[email protected]> wrote: > >> [quote] >> 1.

There won't be any pre configured set of apis, this would allow a system admin to decide exactly what level of access s/he wants to provide to a domainadmin role user. This allows him/her to create multiple end points of mgmt server as well, just like the user api server. > > Regards. > >> >> Regards >> Mice >> >> -----Original Message----- >> From: Rohit Yadav [mailto:[email protected]] >> Sent: Friday, December 07, 2012 4:07 AM >> To: [email protected] >> Subject: Arch Rework RFC: API refactoring updates >> >> Few updates; >> >> 1.

In commands.properties, we should be just able to set policy for user role for each api, if apiname is not declared it's blacklisted. It becomes tricky with plugins.

Multiple API servers can be run with different combination of rules in commands.properties. This would allow separation of policy from mechanism, and multiple roles and end points. For example, an admin can create http routers for these api server, so: <url>/hr, <url>/finance, <url>/marketting can be proxies to different user api servers with different set of whitelisted apis. >> >> Comments, suggestions, flames? >> >> Regards. > > -- Sent from Gmail Mobile
