VPC design principles
As we reach the conclusion of this chapter, it is apt that we dive into the design principles of VPC. When it comes to practicing network architecture in Amazon EC2, adhering to proven principles can guide you in creating an efficient, secure, and easily manageable networking environment:
- Segregation and organization: Consider segregating your VPC into multiple subnets, typically aligned with different layers in a multi-tier application architecture. For example, you might have separate subnets for your web servers, application servers, and database servers. This segregation and organization allows you to have a simplified security and access control, efficient traffic routing, and increased network performance.
- Plan for scalability and flexibility: Design your network architecture to support growth and changes over time. For instance, choose CIDR blocks wisely to allow for future expansion. Use Elastic IPs, which can be dynamically remapped between...
