How do I access the Amazon Aurora DB cluster outside the VPC?
Access the Amazon Aurora DB cluster outside the VPC – To access an Amazon Aurora DB cluster from outside the VPC, use the public endpoint address of the Amazon Aurora DB cluster. You can also connect to an Amazon Aurora DB cluster that's inside a VPC from an Amazon EC2 instance that's not in the VPC by using ClassicLink.
Which authentication options are available for Aurora DB clusters?
Password authentication is available by default for all DB clusters. For Aurora MySQL, you can also add IAM database authentication. For Aurora PostgreSQL, you can also add either or both IAM database authentication and Kerberos authentication for the same DB cluster.
How do Amazon Aurora connections work?
Amazon Aurora typically involves a cluster of DB instances instead of a single instance. Each connection is handled by a specific DB instance. When you connect to an Aurora cluster, the host name and port that you specify point to an intermediate handler called an endpoint. Aurora uses the endpoint mechanism to abstract these connections.

Overview
The following diagram, shows the high-level architecture of an example scenario of using AWS Client VPN and connecting to an RDS instance.
Generating a certificate
For instructions on creating a server certificate using OpenVPN easy-rsa tool, see Mutual authentication.
Creating a VPC and subnets
Create a VPC to host the subnets and the subnet group for the RDS instance with the following code:
Creating a security group
Create a security group to be used by the AWS Client VPN endpoint and the RDS instance with the following code:
Creating an AWS Client VPN endpoint
Create an AWS Client VPN endpoint and attach it to the VPC with the following code. You use the client IP4 CIDR to assign IP addresses to the client connections. Use your own server certificate arn generated in the previous step.
Creating an Active directory
Because the SQL Server RDS instance also uses Windows authentication, create an Active Directory to be associated to the RDS instance:
Creating the SQL Server RDS instance
To create an RDS instance, you need to create a subnet group and a directory service AWS Identity and Access Management (IAM) role. This IAM role uses the managed IAM policy AmazonRDSDirectoryServiceAccess and allows Amazon RDS to make calls to the active directory.
Use cases
Amazon Aurora is a great option for any enterprise application that can use a relational database. Compared to commercial databases, Amazon Aurora can help cut down your database costs by 90% or more while improving reliability and availability of the database.

Migrating Your Databases to Amazon Aurora
If you're currently using Amazon RDS for MySQL or Amazon RDS for PostgreSQL, migrating to Aurora is as simple as creating a snapshot and launching an Aurora instance from that snapshot. You can follow the simple, step by step instructions in the user guide to perform the migration.
Set Publicly Accessible setting of DB instance to Yes
The Publicly Accessible setting for an Amazon Relational Database Service (Amazon RDS) DB instance controls the assignment of a Public IP address to the DB instance.
Run DB instance in a public subnet
A public subnet is a subnet that is associated with a route table which has a route to internet gateway, typically the default route, 0.0.0.0/0. This route enables the DB instances in a subnet to communicate with resources outside the VPC.
Secure the DB cluster from connections from outside the VPC
You can use TLS to encrypt connections that come from outside a VPC because the data transfer happens over the internet. To make sure that you're using the highest level of security, use the ssl-ca parameter to pass the CA certificate, and then enable hostname validation.
Password authentication
With password authentication, your DB instance performs all administration of user accounts. You create users with SQL statements such as CREATE USER, with the appropriate clause required by the DB engine for specifying passwords.
IAM database authentication
You can authenticate to your DB cluster using AWS Identity and Access Management (IAM) database authentication. IAM database authentication works with Aurora MySQL and Aurora PostgreSQL. With this authentication method, you don't need to use a password when you connect to a DB cluster. Instead, you use an authentication token.
Kerberos authentication
Amazon Aurora supports external authentication of database users using Kerberos and Microsoft Active Directory. Kerberos is a network authentication protocol that uses tickets and symmetric-key cryptography to eliminate the need to transmit passwords over the network.
Types of Aurora endpoints
An endpoint is represented as an Aurora-specific URL that contains a host address and a port. The following types of endpoints are available from an Aurora DB cluster.
Viewing the endpoints for an Aurora cluster
In the AWS Management Console, you see the cluster endpoint, the reader endpoint, and any custom endpoints in the detail page for each cluster. You see the instance endpoint in the detail page for each instance. When you connect, you must append the associated port number, following a colon, to the endpoint name shown on this detail page.
Using the cluster endpoint
Because each Aurora cluster has a single built-in cluster endpoint, whose name and other attributes are managed by Aurora, you can't create, delete, or modify this kind of endpoint.
Using the reader endpoint
You use the reader endpoint for read-only connections for your Aurora cluster. This endpoint uses a load-balancing mechanism to help your cluster handle a query-intensive workload. The reader endpoint is the endpoint that you supply to applications that do reporting or other read-only operations on the cluster.
Using custom endpoints
You use custom endpoints to simplify connection management when your cluster contains DB instances with different capacities and configuration settings.
Creating a custom endpoint
To create a custom endpoint with the AWS Management Console, go to the cluster detail page and choose the Create custom endpoint action in the Endpoints section. Choose a name for the custom endpoint, unique for your user ID and region.
Viewing custom endpoints
To view custom endpoints with the AWS Management Console, go to the cluster detail page for the cluster and look under the Endpoints section. This section contains information only about custom endpoints. The details for the built-in endpoints are listed in the main Details section.
Audience
How you use AWS Identity and Access Management (IAM) differs, depending on the work you do in Aurora .
Authenticating with identities
Authentication is how you sign in to AWS using your identity credentials. For more information about signing in using the AWS Management Console, see The IAM console and sign-in page in the IAM User Guide .
Managing access using policies
You control access in AWS by creating policies and attaching them to IAM identities or AWS resources. A policy is an object in AWS that, when associated with an identity or resource, defines their permissions. AWS evaluates these policies when an entity (root user, IAM user, or IAM role) makes a request.
Generating an IAM authentication token
If you are writing programs using the AWS SDK for Java, you can get a signed authentication token using the RdsIamAuthTokenGenerator class. Using this class requires that you provide AWS credentials. To do this, you create an instance of the DefaultAWSCredentialsProviderChain class.
Manually constructing an IAM authentication token
In Java, the easiest way to generate an authentication token is to use RdsIamAuthTokenGenerator. This class creates an authentication token for you, and then signs it using AWS signature version 4. For more information, see Signature version 4 signing process in the AWS General Reference.
Connecting to a DB cluster
The following code example shows how to generate an authentication token, and then use it to connect to a cluster running MySQL.
