Hi

I wish to provide a service which would pass information to customers each of which would be in their own container. Is it possible to share shared memory between my service (which would write to the shmem) and n containers (which would read from the same shmem).

Thanks

Have you consider using the network enabled memcache server which allows sharing information between servers in memory?

No. I've no idea what it is or where to get more information about it.

Hi,

It's a scalable distributed in-memory object store that uses key/variable pairs.

http://www.danga.com/memcached/

It is in use at some very high traffic sites as an in memory cache system, but could be used for sharing information between applications on different servers. Smile

Because it's not what I want.

I would like to have a block of shared memory that is shared by ALL domains on the server. One domain would write to this block and the remainder would read-only from it.

I don't want a distributed memory system. I want a shared memory system in a virtualised environment.
