When setting up an Amazon Web Services network load balancer, specifying correct port configurations ensures uninterrupted connectivity across multiple availability zones.

Amazon Web Services: Understanding VPCs

Amazon Web Services (AWS) provides Virtual Private Clouds (VPCs) to help organisations establish secure and isolated networks.

If you’re working with Amazon Web Services, you’ll encounter Virtual Private Clouds (VPCs) as a fundamental aspect of cloud networking.

A VPC is essentially a virtual network within Amazon Web Services where different departments or teams can maintain isolated subnets.

For example, the audit team, development team, and marketing team each have dedicated subnets within the VPC, ensuring secure communication while keeping resources separate and distinct.

Amazon Web Services enables organisations to establish multiple subnets and route tables, allowing them to manage interactions between different sections of their infrastructure.

This setup enhances security and keeps the organisation’s network efficient.

Configuring a VPC in Amazon Web Services

Creating a VPC in Amazon Web Services involves selecting an IP range, defining subnets, and setting up routing tables.

AWS automates much of this process, making it easy to establish an optimised virtual network.

To create a VPC, search for the VPC service in Amazon Web Services, click ‘Create VPC,’ and then configure the essential settings, such as availability zones, subnet types, and gateways.

AWS then generates the required configurations, enabling an organised network.

Subnet configuration in Amazon Web Services enables organisations to assign specific IP address ranges to different departments, ensuring seamless communication while maintaining security.

Connecting VPCs in Amazon Web Services

In Amazon Web Services, VPC connectivity is crucial for cross-department collaboration.

Suppose an organisation has two separate VPCs—VPC 1 and VPC 2.  AWS provides VPC Peering, which allows seamless communication between these VPCs.

Using VPC Peering within Amazon Web Services, organisations can ensure that resources are accessible across different zones while maintaining security protocols.

This feature is especially beneficial for companies with teams working in multiple locations or those that need to communicate across various cloud environments.
