So I’ve been a bit confused on why we need maintenance mode on something that should always have uptime like an exchange. Every time this happens I have to manually re-enable the market maker bot again because it couldn’t work during maintenance. Also, I can see a lot of people being frustrated if they miss out on trading opportunities if the exchange is down for maintenance.
- Use a load-balancer and redirect all users to server B
- Perform new deployments and upgrades to server A
- After success, balance all users to server A
- Perform upgrade on server B
This should take away downtime.
