If you’re new to AWS, you should be able to run your blog at AWS in their free usage tier for one year. After one year, it will cost about $14.64 per month. But, if you spend $62 up front on a reserved micro instance, you can reduce the monthly fee to $3.66 (total monthly fee of $8.83). If you buy a three year reserved micro instance for $100, you can reduce the total monthly fee to $6.44. For hosting WordPress, it makes sense to buy a reserved instance.

But this can be reduced to $11.91 by purchasing a one year reserved small instance for $195 (total adjusted monthly rate of $28.16).

Note: The estimates above do not include additional costs for S3 storage and bandwidth – but these costs are typically comparatively smaller. And, we don’t use Amazon’s Remote Database Service (RDS) specifically to minimize costs.

If you purchase a reserved instance and then later regret doing so, Amazon offers a marketplace for selling unused portions of reserved instances (for a small commission). I’ve found it works well and have sold two instances within a few weeks.

However, moving your site from a micro instance to a small instance is non-trivial and it’s not documented here. If you think you’ll have a successful blog, start with a small instance.
