# CDK fck-nat

A CDK construct for deploying NAT Instances using [fck-nat](https://github.com/AndrewGuenther/fck-nat). The (f)easible (c)ost (k)onfigurable NAT!

* Overpaying for AWS Managed NAT Gateways? fck-nat.
* Want to use NAT instances and stay up-to-date with the latest security patches? fck-nat.
* Want to reuse your Bastion hosts as a NAT? fck-nat.

fck-nat offers a ready-to-use ARM and x86 based AMIs built on Amazon Linux 2 which can support up to 5Gbps NAT traffic
on a t4g.nano instance. How does that compare to a Managed NAT Gateway?

Hourly rates:

* Managed NAT Gateway hourly: $0.045
* t4g.nano hourly: $0.0042

Per GB rates:

* Managed NAT Gateway per GB: $0.045
* fck-nat per GB: $0.00

Sitting idle, fck-nat costs 10% of a Managed NAT Gateway. In practice, the savings are even greater.

*"But what about AWS' NAT Instance AMI?"*

The official AWS supported NAT Instance AMI hasn't been updates since 2018, is still running Amazon Linux 1 which is
now EOL, and has no ARM support, meaning it can't be deployed on EC2's most cost effective instance types. fck-nat.

*"When would I want to use a Managed NAT Gateway instead of fck-nat?"*

AWS limits outgoing internet bandwidth on EC2 instances to 5Gbps. This means that the highest bandwidth that fck-nat
can support is 5Gbps. This is enough to cover a very broad set of use cases, but if you need additional bandwidth,
you should use Managed NAT Gateway. If AWS were to lift the limit on internet egress bandwidth from EC2, you could
cost-effectively operate fck-nat at speeds up to 25Gbps, but you wouldn't need Managed NAT Gateway then would you?
