# Stacks

- [Network](#Network)

## Network

This network stack is optimized for development purposes and leverages on resources that has low cost when turned off. 

```

https://s3.amazonaws.com/chrvadala.aws-cloud-stacks/public/network/network-latest.yml

```

Network stack set up the following resources:

- *VPC*

- *2 Public Subnets*

- *2 Private Subnets*

- *1 NAT Instance* that provides internet connectivity to Private Subnets. It can be powered off when private resources don't need internet access.

- *1 BastionHost* that provides SSH access to the network from any connection coming from trusted networks. It can be powered off when there aren't SSH access needs.
