Final answer:
Default VPCs and custom VPCs are concepts related to Amazon Web Services (AWS) Virtual Private Cloud (VPC) service. Default VPCs are automatically created and come with default settings, while custom VPCs are manually created and allow for more customization. Some differences include automatic creation, IP address range control, and flexibility.
Step-by-step explanation:
Default VPCs and custom VPCs are concepts related to Amazon Web Services (AWS), specifically their Virtual Private Cloud (VPC) service. A default VPC is provided automatically by AWS and is meant to be used as a starting point for launching instances. It comes preconfigured with default settings such as subnet and security group.
On the other hand, a custom VPC allows you to create a virtual network with your own specific settings and configurations. You can define your own subnets, routing tables, and security groups.
Some differences between default and custom VPCs include:
- A default VPC is automatically created in each AWS region, while you need to create a custom VPC manually.
- A default VPC has predetermined IP address ranges, while you have more control over IP address ranges with a custom VPC.
- A default VPC has certain limitations and restrictions, while a custom VPC offers more flexibility and customization options.
