When I was in a similar position we switched to Digital Ocean (no affiliation) simply because of their predictable pricing model, and that worked very well for us. Linode would have worked the same. Another service that I've used is using dedicated servers from OVH. Of course all this is my personal opinion but the obscurity of AWS pricing (predict/calculate ec2 hours + predict/calculate network traffic costs + S3 storage class/tiers costs) is a major turnoff for me. In some situations all that granularity could have costs benefits but in my experience it does tend to run and suddenly a we end up paying $600+/mo for a $20/mo instance because we hit some cap thresholds (true story)... Good luck figuring this out!
