Building a redundant CloudStack management cluster. Building and maintaining an open-source-driven clustered environment for Apache CloudStack management server with GNU Linux, HAProxy, HeartBeat, Bind, OpenLDAP and other tools.

2. About Tucha
Here I’ll be telling something about our company
(started as an ISP in 2005), our cloud experience
(back in 2012 we were the first who started to
provide IaaS in Ukraine), our cloud’s volume (several
hundreds of virtual machines), our adherence to OSS
ideology and so on.
It would be amazing to have it illustrated somehow :)

8. Things to Get Done and Checked
Naming, IPv4 and VLAN assignment plans
Networks, virtual machines, security policies
Auxiliary services (DHCP, LDAP, NTP and others)
MySQL servers (cross-replication, failover cluster)
Apache CloudStack management servers
Load Balncers (heartbeat, haproxy, iptables)
Stats collecting and states monitoring suites
Backup automation, disaster decovery plan
Crash tests, performance measurement and stuff :)
