- [Instructor] We know that CloudWatch works with metrics … and alarms and will alert us when there's an issue … with one of our resources. … But we can also use CloudWatch Events. … An event is a near real-time stream of system events … that are being monitored by CloudWatch … and any change to an actual resource at Amazon … can actually fire off an event, … which in turn is linked by a rule defining … what you want to do when that event happens. … If you think of EC2 instance, … the instance boots, it runs for a while, … it shuts back down. … What happens if the EC2 instance boots, … but runs into trouble? … Well, events communication from that EC2 instance … are generated, indicating it's in trouble. … What can happen when that event fires, … is it matches a rule that says, … if that EC2 instance is having trouble booting … and running on the hardware where it was first launched, … let's automatically route that EC2 instance … to other hardware and start it again. … That's a service called EC2 auto recover …
