Amazon Relational Database Service (Amazon RDS) makes it easy to set up, operate, and scale a relational database in the cloud.
It provides cost-efficient and resizable capacity while automating time-consuming administration tasks such as hardware provisioning, database setup, patching and backups.
It frees you to focus on your applications so you can give them the fast performance, high availability, security, and compatibility they need.
AWS RDS Security
AWS provides multiple features to provide RDS security
DB instance can be hosted in a VPC for the greatest possible network access control
IAM policies can be used to assign permissions that determine who is allowed to manage RDS resources
Security groups allow controlling what IP addresses or EC2 instances can connect to the databases on a DB instance
Secure Socket Layer (SSL) connections with DB instances
RDS encryption to secure RDS instances and snapshots at rest.
Network encryption and transparent data encryption (TDE) with Oracle DB instances

RDS Authentication and Access Control
IAM can be used to control which RDS operations each individual user has permission to call
SSL to Encrypt a Connection to a DB Instance
Encrypt connections using SSL for data in transit between the applications and the DB instance
Amazon RDS creates an SSL certificate and installs the certificate on the DB instance when RDS provisions the instance.
SSL certificates are signed by a certificate authority. SSL certificate includes the DB instance endpoint as the Common Name (CN) for the SSL certificate to guard against spoofing attacks
While SSL offers security benefits, be aware that SSL encryption is a compute-intensive operation and will increase the latency of the database connection.
IAM Database Authentication
IAM database authentication works with MySQL and PostgreSQL.
IAM database authentication prevents the need to store static user credentials in the database because authentication is managed externally using IAM.
IAM database authentication does not require password but needs an authentication token
An authentication token is a unique string of characters that RDS generates on request.
Authentication tokens are generated using AWS Signature Version 4.
Each Authentication token has a lifetime of 15 minutes
IAM database authentication provides the following benefits:
Network traffic to and from the database is encrypted using Secure Sockets Layer (SSL).
helps centrally manage access to the database resources, instead of managing access individually on each DB instance.
enables using IAM Roles to access the database instead of a password, for greater security.

What is Amazon RDS Read Replicas?
The read replica operates as a DB instance that allows only read-only connections. Applications connect to a read replica the same way they do to any DB instance. Amazon RDS replicates all databases in the source DB instance. The Oracle DB engine supports replica databases in mounted mode.
What is Amazon RDS Multi AZ?
RDS Multi-AZ. Amazon RDS Multi-AZ deployments provide enhanced availability for database instances within a single AWS Region. With Multi-AZ, your data is synchronously replicated to a standby instance in a different AZ.
Amazon Web Services (AWS) is the world’s most comprehensive and broadly adopted cloud platform, offering over 200 fully-featured services from data centers globally. Millions of customers—including the fastest-growing startups, largest enterprises, and leading government agencies—are using AWS to lower costs, become more agile, and innovate faster.
What is Amazon RDS?
Amazon Relational Database Service (RDS) is a managed SQL database service provided by Amazon Web Services (AWS). Amazon RDS supports an array of database engines to store and organize data. It also helps with relational database management tasks, such as data migration, backup, recovery, and patching.
Here is a fully dedicated video on AWS RDS (Relational Database Services)
Amazon RDS facilitates the deployment and maintenance of relational databases in the cloud. A cloud administrator uses Amazon RDS to set up, operate, manage and scale a relational instance of a cloud database. Amazon RDS is not itself a database; it is a service used to manage relational databases.
What are the benefits of AWS RDS?
The main benefit of Amazon RDS is that it helps organizations deal with the complexity of managing large relational databases. Other benefits include the following:
Ease of use. Admins don't need to learn specific database management tools. They also can manage multiple database instances using the management console. RDS is compatible with database engines that users may already be familiar with, such as MySQL and Oracle And it automates manual backup and recovery processes.
Cost-effectiveness. According to AWS, customers only pay for what they use. Also, the time spent maintaining instances is reduced, because maintenance tasks, such as backups and patching, are automated.
The use of read replicas routes read-heavy traffic away from the main database instance, reducing the workload on that one instance.
RDS splits up compute and storage so admins can scale them independently.
