It allows users to collect and track metrics, monitor log files, set alarms, and automatically react to changes in AWS resources. CloudWatch enables proactive monitoring of AWS resources, ensuring efficient resource utilization and timely responses to performance issues.

Amazon RDS (Relational Database Service) is a fully managed relational database service provided by AWS. It offers high availability and automatic failover capabilities for databases running on supported engines such as MySQL, PostgreSQL, and SQL Server. With Amazon RDS Multi-AZ deployments, the service automatically provisions and maintains a standby replica in a different Availability Zone for automatic failover in case of a primary database failure.

Implementing multi-AZ (Availability Zone) deployments involves distributing critical components of the application across multiple Availability Zones within an AWS region. This ensures high availability and fault tolerance by providing redundancy and automatic failover in case of an infrastructure failure in one Availability Zone. It is a best practice for designing fault-tolerant architectures on AWS.

Amazon IAM (Identity and Access Management) is a service that enables centralized control of access to AWS resources.
