TLDR: Amazon Lightsail 1GB will melt down with less than 15% sustained cpu usage
Amazon Lightsail launched to much fanfare last week, threatening the business of competitors like DigitalOcean, Linode, OVH, Atlantic.net and many others who have long offered simple, cheap, all-included price VPS servers.
At VpsBenchmarks, we specialize in testing this type of VPS so we wasted no time firing up an instance of the 1GB 1 core $10 flavor of Lightsail. I setup our web app on this VPS, pointed traffic at it and also ran Sysbench tests.
That didn’t go well.
It took only 2 hours after setup and an average 25% cpu usage for the cpu steal to start climbing, just a few percentage points at first, but more than 80% after one more hour. At this point the web server was unresponsive, requests that normally take 60ms were now taking several seconds. This was on happening on 12/4 01:00
