Monitoring Infrastructure with CloudWatch (Writing in progress…)

When you have an infrastructure in AWS (or even on-premise), CloudWatch is a solution to monitor it; resources to monitor may be databases, virtual machines, disks, web applications… as on-premise solutions like Nagios. CloudWatch allows to collect logs, metrics and events in order to improve performance and optimization. It is important to know that an agent has to be installed inside an AWS instance (or even on-premise) in order to monitor it using CloudWatch.
