Upgrade Strategies• In-place update of servers

– Quick and easy– Good for simple code updates– Avoid when changing system/library

files

• Relaunch fresh servers– More involved but cleaner– Good when rolling out major update, or

changing system/library files


13

Clone vs. add server• Clone

– Copies all server-specific settings– EIPs, hostnames, disabled scripts, …– Good when replacing a server as-is

• Add– Creates a fresh server from template– Inherits deployment settings, need to

manually set server-specifics– Good when server template has

changed


14

System update step-by-step1. Launch replacement servers2. Quick test of replacement servers3. Run any pre-upgrade DB migrations4. Put maintenance page up5. Halt old server processes6. Run DB migrations7. Start new server processes8. Test new servers9. Switch EIPs from old to new servers10. Test site, watch log files11. Run post-upgrade DB migrations12. Terminate old servers when convenient

Cloud Principle #1:grab the next one!• Database management

– Always roll forward, never fail-back– Animoto upgraded large->XL @600 servers

• App server management– Always roll forward, never fix in-place– www1 bust? Launch www3! Then

troubleshoot

• Smart sysadmins have the urge to fix…


19

Managing Cloud Deployments• Resources On Demand• More Automation• Less Administration• Full Control
