19. AWS CloudWatch Alarms
• Example Use Cases
• EC2: Tell me if my instance needs attention
• DynamoDB: Help me balance cost and performance
• Billing: Tell me when I'm exceeding my AWS budget
20. • Fallacies of Distributed Computing
• The network is reliable
• Latency is zero
• Bandwidth is infinite
• The network is secure
• Topology doesn't change
• There is one administrator
• Transport cost is zero
• The network is homogeneous

21. Inside
• 1 datapoint per metric, per minute, per resource
• AWS is VERY big, VERY dynamic, growing VERY fast!
• Aggregating data to produce meaningful
statistics
• What is CPU utilization across my fleet?
• Today it is 50% - Yay!
• Yesterday it was 25% – Huh?!
• Last week it was 5% – Yikes?!
22. Inside
• Data Access Patterns
• Realtime data can be VERY valuable to wide
audiences – ‘Million Dollar Minutes’
• LOTS of older data, that might still be VERY valuable
to narrow audiences
• Be the Last Man Standing
• What happens when there is a power event in a DC?
• Who watches the watchmen?
