One of the major challenges of using Ymir to host a WordPress site on AWS Lambda is estimating cost. AWS uses usage-based pricing for a lot of its services. This makes calculating the cost of hosting a WordPress site on AWS challenging.
I’ve been running my personal site on AWS Lambda for a few months now. This has given me a few months of data on the cost of host a WordPress site using Ymir. While this is just one example, it’s still an excellent opportunity to look at the real world cost of using AWS Lambda to host a WordPress site.
