To create an RDS for Db2 instance, one of the prerequisites is to configure the virtual private cloud (VPC) appropriately.
Amazon RDS for Db2 is a fully managed solution on scalable hardware designed to deliver optimal performance in minutes.
With Amazon Virtual Private Cloud (Amazon VPC), you can create a logically isolated network dedicated to your AWS account.
Amazon VPC includes subnets, route tables, and network access control lists (ACLs) to control how network traffic flows into and out of AWS resources.
Amazon VPC provides complete network isolation and security, and it enables you to control who and what can access your resources.
Best practices for creating an Amazon VPC for use by Amazon RDS for Db2 include using multiple Availability Zones, separating public and private subnets, using private subnets for sensitive data, and limiting the scope of security groups.
Selection criteria for choosing a VPC and other AWS features depends on your organization’s scale and security needs.
By following best practices such as isolating public and private subnets, using security groups effectively, and using VPC endpoints, you can build secure and scalable network architectures that protect your cloud resources.
Through automation using tools like Lambda and AWS CloudFormation, you can further simplify the process of creating and managing VPCs.
