We will name our vpc “my-vpc” under Name tag and select our CIDR block as 10.0.0.0/24.

Step 5: Since we have created our VPC, now we need to create subnets within our VPC

Routing

  • In this scenario, the VPC wizard updates the main route table used with the private subnet, and creates a custom route table and associates it with the public subnet. In this scenario, all traffic from each subnet that is bound for AWS (for example, to the Amazon EC2 or Amazon S3 endpoints) goes over the internet gateway. The database servers in the private subnet can't rece…

Security

  • AWS provides two features that you can use to increase security in your VPC: security groups and network ACLs. Security groups control inbound and outbound traffic for your instances, and network ACLs control inbound and outbound traffic for your subnets. In most cases, security groups can meet your needs; however, you can also use network ACLs if you want an additional …

  • You can use the VPC wizard to create the VPC, subnets, NAT gateway, and optionally, an egress-only internet gateway. You must specify an Elastic IP address for your NAT gateway; if you don't have one, you must first allocate one to your account. If you want to use an existing Elastic IP address, ensure that it's not currently associated with anothe...
