Glacier- low-cost- storage for data archiving and backup- optimized for data that is infrequently
accessed

Static site example
2. copy static site to S3 bucket: aws s3 sync output/ s3://devops-by/
14
Static site3. Create new Bucket policy and add read-only rights:{
"Version": "2012-10-17","Statement": [
{"Sid": "StaticSitePerm","Effect": "Allow","Principal": "*","Action": "s3:GetObject","Resource": "arn:aws:s3:::devops-by/*"
}]
}

RDS21
22
Multi-AZ Deployments- Amazon RDS automatically creates a primary DB
Instance and synchronously replicates the data to a standby instance in a different Availability Zone (AZ).
- Performs an automatic failover (CNAME record changes from the main DB to the standby).
23
Promote Read Replica- Before you promote Read Replica, we recommend that
you stop any transactions on the master and wait for the Read Replica committed all master transactions.
- Note that the promotion process takes a few minutes to complete.
- When you promote a Read Replica, replication is stopped and the Read Replica is rebooted as part of the promotion.
