Monitoring Priority in Cloud• IaaS– High CPU is good, otherwise you’re wasting $$

• PaaS– APM is a must-have – you cannot see the server!

• SaaS– May still be able to collect metrics via API

End User Experience• On average 87% of the response time is in the Browser• Your monitoring strategy should start with user experience
