3.Alerting

4. Focus on Service vs Component Service Component • Web Site Overall • General Availability and • Single Web Server Performance • Remove from the service if • Redundancy Loss poor availability or • Other “global” issues ie correctness Performance • Immediate Action required 24/7 • Self Healing (especially cloud) • Automated Actions for Healing and Scaling • 24/7 optional 4

5. Proactive and Reactive Proactive Reactive • Needs attention to prevent future • When things are bad or problem problem eminent • Working Hours • 24/7/365 • Replication Capacity close to • Server Crashed limit • Will run of space in a week • Replication Broke • Backup is taking longer than • Servicing Queries Slowly desired • Backup Failed 5

6. Service Impacting and Operational Service Impacting Operational • Directly Impacting • Are backup being taken? Application • Is configuration valid/secure ? • Service Down • Is replication running • Service Slow and up to date ? 6
