Building the Cooperative Community Cloud with Debian
DebConf22

####Purpose of the talk - The talk will cover the technical architecture of the redundancy infrastructure and the managed operation platform architecture of a highly flexible hosting environment. It will focus on the benefits of Debian for small and medium sized hosting providers. - For people interested on how Debian can perfectly provide a software system for webhosting. - Exchange of experiences with Debian's high availability maintainers is highly appreciated! ####Cooperative Cloud Computing - Hostsharing eG, founded in 2000, is a cooperative that provides Infrastructure as a Service and Platform as a Service for about 300 members. The membership includes a wide range of users from individuals and freelance developers to small and medium enterprises and organisations. High Performance, High Availability, Data Security and Data Protection are key mainstays to the success of the cooperative together with digital sovereignty, sustainability and excellence. The Cooperative Community Cloud of Hostsharing is entirely based on Debian. ![Cooperative Cloud Computing](https://lxtec.de/debarchiv/ccc_eng.svg"Cooperative Community Cloud") ####How is it done? - The fundamental building block of the hosting system are redundancy groups consisting of several servers. - Virtualization is done with KVM. - The OS is installed on a kernel-based softraid xfs filesystem. - The member specific data is located at a Open ZFS (ZOL). - Backups are organized via a DRBD-System and a ZFS-Send-Receive System via zrepl (not yet distributed by Debian Repos). - There are several administration applications which are developed by the hostmasters. - Debian software packages and some defaults are distributed by SALT-STACK.
