SAA-C03 AWS Services

Question 1

Amazon CloudWatch

Answer 1

• Monitoring tool for your AWS resources and applications.
• Display metrics and create alarms that watch the metrics and send notifications or automatically make changes to the resources you are monitoring when a threshold is breached.
• CloudWatch is basically a metrics repository. An AWS service, such as Amazon EC2, puts metrics into the repository and you retrieve statistics based on those metrics. If you put your own custom metrics into the repository, you can retrieve statistics on these metrics as well.
• CloudWatch does not aggregate data across regions. Therefore, metrics are completely separate between regions.

Question 8

Amazon EventBridge

Answer 8

Amazon EventBridge (formerly called CloudWatch Events) is a serverless event bus that makes it easy to connect applications together. It uses data from your own applications, integrated software as a service (SaaS) applications, and AWS services. This simplifies the process of building event-driven architectures by decoupling event producers from event consumers. This allows producers and consumers to be scaled, updated, and deployed independently. Loose coupling improves developer agility in addition to application resiliency.
