AWS Reserved Instances and Purchasing Strategy

For me I purchased the reserved instance( a micro one ) last october. I planned to use it as the host of my personal site (for some projects' demo) and weblog. As the post claims, the main concern before purchasing a reserved instance is it cannot scale. My personal site, which I believe will not gain so much view in all 3 years, benefits the most from the average low price.

for those suggests GithubPages to host one's blog, thank you for your information. Gh-pages is a great option and I recommend it too if one just need a place to host a static blog. However for me, I need a VPN server at the same time because yes, I live in China. That's why I chose AWS services.

The last time I did the numbers on reserved instances, I was initially surprised (and subsequently not surprised at all) to find that the present value cost of reserved vs payg was close to identical assuming a typical A- rated corporate debt rate. Given that my cost of capital is higher than Jeff's but my inherent risk (in demand i.e. workload predictability) low, it made sense to go reserved.
