Nice writeup, I like it and would definitely bookmark for future reference.

One weak take however in the article that I felt not quite right is the pricing saving part. By saying 1/4 of the price. I was expecting to see the AWS bill in the range of $10k/month, or more but it turned out to be just around ~$550 or, a total saving of $420.

Whith the above said, it does really make me questioning whether it worth the hassle of migration because, probably, one of the main reasons to move away from AWS is to save the cost.

Finally, let me conclude with this comment from /r/programminghumor:
