A static website

On a AWS free account this will cost around $0.60 per month (not including domain registration)

A cloudfront hosted website that uses a private s3 backend

                    +------+       +--------------+      +------+
                    |      |       |              |      |      |
                    | DNS  | +---> |  CloudFront  | +--> |  S3  |
                    |      |       |              |      |      |
                    +------+       +--------------+      +------+

And some monitoring

Cloudwatch billing and usage alerts to pager duty based of customisable thresholds

                    |            |       |       |      |             |
                    | Cloudwatch | +---> |  SNS  | +--> |  Pagerduty  |
                    |            |       |       |      |             |
                    +------------+       +-------+      +-------------+

And finally some overbilling protections

If actual or forecasted budget is exceeded an email is sent and the static website shutdown automatically

            +------------+       +-------+      +-------------+      +-------------+

            |  Budgets   | +---> |  SNS  | +--> |   Lambda    | +--> |  CloudFront |
            |            |       |       |      |             |      |             |
            +------------+       +-------+      +-------------+      +-------------+
