Back in early 2009, I was launching a file storage web service similar to Dropbox (without the client, but with an API with OAuth 1 support) using AWS Ec2 and S3. I planned to use HTTPS, but it was expensive for me (as a college dropout), and the website is still online without it. I abandoned the project afterward. Recently, I started to migrate it from AWS to Google Cloud Platform, and one of the goals was to add HTTPS to it. However, I haven't had much time to finish the migration, and it's still not being served as HTTPS (even though it has all other sorts of protection that were the norm back then). I wonder how many other "legacy websites" have a similar issue (which I don't find justifiable for anything 'in production').
