I'm working at a small SaaS startup, and I've noticed that our development and staging servers on AWS EC2 tend to go down quite often—usually overnight or early in the morning. When I try to access the site in the morning, I get the dreaded "This site can't be reached" message. After that, I have to Slack our DevOps guy who restarts the instance, and everything starts working again. This issue happens about three to four times a week, wasting around 20-30 minutes each time for both me and the QA team. I'm considering building a small tool to automatically detect and restart instances using the AWS SDK when this happens. Before I fully dive into that, I'm curious: does anyone else experience this kind of recurring downtime in their dev or staging environments? How do you handle it? Are there good solutions like auto scripts, using CloudWatch, or do you just resort to manual restarts? It would be helpful to know if this is a common issue and if my idea for a self-healing tool is worth pursuing.

Before diving into creating an automated tool, it might be more effective to figure out the root cause of these outages. There are likely existing tools within AWS that can help manage this, such as health checks for EC2 and ECS. It's essential to understand why your server is going down in the first place before applying a band-aid solution.
Sounds like a practical approach would be to add some automation and set up health checks that can restart the server if it goes down. But don’t forget to explore your application's performance and stability to prevent these issues from happening in the first place!
If things are failing on a schedule, it might be something simple like a cron job that shuts down the server overnight. If your DevOps isn't already doing that, it might be worth suggesting. Also, AWS provides plenty of built-in health checks that can help manage the instances better.
Exactly! Plus, it's crucial for your app to self-start without any manual intervention—use cloud-init or similar tools to make that possible.
Right, and really, automating a restart without knowing the underlying issue could lead to more problems down the line. Make sure to work with your DevOps guy to get to the bottom of this.
