This was my preparation note while I appeared for AWS solution architect – Associate exam. I cleared it in first attempt with good margin. Sharing it here as I guess it helps for beginners and aspirants.
Other notes in this series.
CloudWatch
- For monitoring resources.
- Monitoring service in AWS. Not to be confused with cloud trial which is for auditing.
- With cloudwatch you monitor AWS resources such as EC2, S3,RDS, etc.
- Cloudwatch gets us metrics such as CPU utilization, disk, status, network. It doesn’t give metric on memory.
- Allows creating dashboard.
- Supports events. Example, whenever a new EC2 is provisioned, it could be setup through events to invoke a lambda function and add to ELB.
- Supports alarms such as actioning when the EC2 CPU stay at 80% for a min. Action could be AWS resources specific or notification.
- Supports log monitoring, even supplication log monitoring. Needs an agent to be back installed in EC2.
- Need custom cloudwatch metrics to monitor EC2 health
Cloud Formation

- Infrastructure as code.
- Setup the complete deployment model via code.
- Need template (JSON). Can be designed or avail the existing one.
