I have a social networking site http://www.retbranche.com running social engine 4.2.6 script and sometimes I'm having sever overload issue causing by slow MSQL queries (a developer is working on it).
I'm on a dedicated server quite powerful, I'm also using Amazon s3 as my default storage system and www.CloudFlare.com a CDN service to speed up my site. Amazon SES handle all my emails through SMTP.
So now I'm thinking about using Amazon EC2 and other amazon services if necessary for better performance. Can you help me out? How much that will cost?
PS. Contractors should have strong reason to convince me for the reason to go to cloud. Right now my website has load averages around 60 and goes down. I would like to find out the reason for it and whether moving to EC2 cloud makes sense.
