Summary
In this chapter, we took a deeper look at the AWS CloudWatch service. We focused on the metrics and what makes up a metric. We looked at the different types of metrics available from AWS, starting with basic metrics on the Free Tier, then moving on to detailed metrics, and finally learned how to create custom metrics. We also learned how to use these metrics to create custom dashboards in CloudWatch and discovered how the dashboards could be shared with not only team members who had IAM access, but also how they can be shared with others outside of our AWS account.
We also looked at EventBridge, the service that has taken over CloudWatch Events. We learned how using event buses for AWS services, custom application events, and even SaaS providers can help drive event-driven architectures.
In the next chapter, we are going to look at the various types of logs that can be generated from the different Amazon services. This includes VPC Flow Logs, Elastic Load Balancer logs...
