However, very few compute jobs these days can work completely disconnected from other networks. (For more details, see our documentation on how we configure networks for our customers at TinyStacks.) ![]() By hosting compute in a private subnet, you limit the potential attack surface area available to hackers. A private subnet only has routes that connect to other subnets in the network.Ī private subnet is a great tool for enhancing the security of your Web applications. A public subnet contains a route to an Internet gateway, enabling both inbound and outbound traffic from and to the public Internet. At creation time, you can divide your VPC into subnets (logical groups of IP addresses).ĭepending on how you define your networking routes, a subnet can be either public or private. Let's say you're deploying a new VPC on AWS. But these days, many AWS features (such as Amazon EC2) can only be used in the context of a VPC.Īnd that's where NATs come into play. In the past, you could create AWS resources by default in a public address space. ![]() A VPC is a private IP address space that functions much like a standard physical network. The use of NATs has become prevalent on AWS with the company's emphasis on Virtual Private Clouds (VPCs). In simplest terms, a Network Address Translation (NAT) server is a compute instance that enables traffic between private subnets in a network and other networks. Which one should you use? Let's look at some of the elements that might factor into your decision. AWS supports both NAT Instances and NAT Gateways.
