To answer the title question, the best place is probably the Cloud SIG mailing list. More about the Cloud SIG in general at https://fedoraproject.org/wiki/Cloud_SIG, and specifically the mailing list https://admin.fedoraproject.org/mailman/listinfo/cloud. > I'd like to know the differences in the capabilities between fc17/fc18 and > RHEL? It depends what thing you're talking about. Many cloud-related packages are included as part of EPEL, which is a Fedora-backed project to build extra packages for Enterprise Linux. > Are these clouds primarily for data storage, or can I use fedora as a > front-end where my mail applications (such as webmail and pop/imap) > would access data in an Amazon cloud? This still leaves a single point > of failure in my fedora system, however. We don't actually have a cloud-backed data storage service. There is work in progress to package OwnCloud, which is a web service you can install to run your own cloud-backed storage system. Alternately, there is SparkeShare, which uses Git as a backend, making it easily adaptable to a cloud solution. I don't quite understand the question about front end mail applications. Fedora has plenty of mail clients which can use any remote server, cloud-hosted or not. > What is the difference between OpenStack, Sheepdog, and Eucalyptus? These are all software to build your own cloud infrastructure. OpenStack and Eucalytus as similar, in that they let users spin up virtual machines in a manner similar to Amazon EC2 or Rackspace cloud (although they're very different in implementation). Sheepdog is a more low-level technology designed to to provide block storage to virtual machines. It's perhaps best thought of as a _component_ of a private cloud environment, not a whole solution. > I'm trying to create a fully fault-tolerant mail system, where if the > front-end webmail system or the back-end spam/virus processing, or > even the mailboxes, somehow become inaccessible, it is mirrored on > another system and will automatically fail over to that system. This is very possible with traditional, non-cloud server technology (since it's been a requirement for many institutions since the 1970s). You could certainly build it on top of cloud technology or *in* a cloud like Amazon EC or in your own private cloud. > Is there a single product that will do this, or do I need to master > all of the above programs? You'll definitely need to master some server software, but not necessarily the above. Cloud makes it easy to spin up the multiple servers that might be part of your architecture. > I'd appreciate it if someone could point me to a discussion on the > different technologies, and a description for an advanced admin to get > started implementing this solution. I guess I'd start with a book on IMAP servers. The O'Reilly one is over a decade out of date, but there's one from No Starch which might be helpful. -- Matthew Miller ☁☁☁ Fedora Cloud Architect ☁☁☁ <mattdm@xxxxxxxxxxxxxxxxx> -- users mailing list users@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe or change subscription options: https://admin.fedoraproject.org/mailman/listinfo/users Guidelines: http://fedoraproject.org/wiki/Mailing_list_guidelines Have a question?
