Vultr is my go-to source when I want anything to do with cloud computing. their service is extremely good. first, they offer one of the best billing systems I have used. they pay as you go plan doesn’t charge you when the server is shut down while most of the other services charge a nominal fee. especially when trying to run promotional apps online, we usually run it a few days/hours at a time, and then the service won’t run for a couple of days to so. so the billing system was like a blessing for us. they have servers across the world which help in setting up hosting or apps closest to your target audience thus increase the speed and overall user experience. the servers are quite fast, I’m not saying they have the fastest servers out there but they are fast enough and worth the money. also, I like the server customization options and the interface.
