Our producer nodes are bare metal servers owned by us.
On the cloud, you can’t obtain the maximum performance for the CPU.
Thus, running producers’ nodes on bare metal machines allow us to maximum transactions throughput on EOS.
Also, the producer contains sensitive data of the producer node, so having our producer close to us can evict censorship in the future.
We have several backups, and we always have redundancy in all aspects of the infrastructure design, never leaving a single point of failure.
