Ask HN: Digital Ocean vs. AWS for a Growing Wordpress Site

I run a website that is growing in traffic and as of this month will clock 1.5 million monthly hits. I am now starting to face a few downtimes with my DO droplet (2 GB RAM, 2 CPU). Would you recommend that I now move to AWS or should I continue with a larger instance on DO and save money? Don't have indepth knowledge about setting these things up, have a friend who helps me out so would prefer something that really has very minimal downtime or issue-fixing. Thanks!
