Transcript of Leveraging CentOS and Xen for the Go Daddy Private Cloud
PARADIGM CHALLENGES• Traditionally a very static environment• Management, monitoring, security tools
good at this• Mindset shift: care about services, not
servers• Cloud ideal vs. reality
STACK ATTACK
WHY NOT XEN SERVER?• XenServer is a good package of Xen
• Microsoft support
• Good approach if that’s what you need
• Support of XenServer is more difficult
• It looks like Linux, but can’t treat it like Linux
• Need something that is more flexible
WHY CENTOS + XEN?• Stock CentOS, not an appliance
• Much experience supporting it
• Leverage larger Linux user community
• Drops in to management/monitoring systems
• Patch management/upgrades
• Better fit for our cloud – no fighting with XenServer for control
GETTING TO ‘YUM INSTALL XEN’• Interest/demand from community
• Can run Xen on CentOS today, but non-trivial
• Mostly a packaging problem
• Teams from CentOS, Xen, Citrix, Rackspace, and Go Daddy
• QA and usability sanity checks
