Autoscaling isn’t only used the grow the number of servers under load, but also to guarantee availability of a fixed number. If the max is set to 1, the bastion host is protected against hardware failure, zone outages, or just you screwing up. Accidentally killed your bastion host? No problem, within a few minutes autoscaling will have provisioned a new one and you’re good to go again.

Arstechnica runs on WordPress on AWS, and they have a really nice series of articles about it. Sure, you could use just one EC2 instance for everything, but on a high traffic website you would need a bit more.
That’s why I wrote an Ansible playbook, to configure and update my router and access points. It’s nice having this almost as infrastructure-aa-code, with all configuration changes under version control with a clear commit message. The script is available at https://github.com/danielvijge/openwrt-configuration-ansible, but do make some changes to match your configuration. I keep my network configuration (inventory file) in a separate, private GitHub repo, as that contains passwords etc.
