To make data count and to ensure cloud computing is unabated, companies and organizations must have highly available databases. Load balancing : Traffic is distributed across multiple servers to prevent any one component from becoming overloaded. If a primary server fails, a backup server can take over and continue to serve requests.

This is basically the position of the major cloud providers, they will all take care of it for you by 2030 or so. A rough guide if you don’t have any better data is that with no traffic to a system it will be 10% utilization and use 30% of peak power, 25% utilization uses 50% of peak power, and at 50% utilization it uses 75% of peak power.
