The tutorials work on any VPS probably. And, the load balancer part, you can build that yourself with a boatload of solutions like haproxy, nginx and whatnot...
Sure, but you still have a single point of failure.
Wouldn't the hosting provider's load balancer also be a single point of failure? Unless they also have a backup which is easy to do yourself as well.
Just wanted to make sure I was understanding.
Could be. But Digital Ocean does not provide you with a movable IP that you could point at a different load balancer when the old one becomes faulty. With a movable IP or a cloud based load balancer a single point of failure could be prevented. DO does not offer any of them.
I see, it's the movable IP that's the issue. Thanks for the clarification.
