In both cases, when using virtually-synchronous replication, the process will require certification from each node and local (by node) write; as such, the number of writes is NOT distributed across multiple nodes but duplicated. It will also allow us to redirect read/write traffic to the primary and read-only traffic to all secondaries.

HA in PostgreSQL databases delivers virtually continuous availability, fault tolerance, and disaster recovery. In general terms, to achieve HA in PostgreSQL, there must be: Redundancy: To ensure data redundancy and provide continuous performance when a primary server fails, multiple copies of the database reside in replica servers.

Because of its NoSQL origin and document architecture design, MongoDB is much more flexible and scalable than SQL databases such as MySQL. However, it is available in other open-source versions of MongoDB, such as Percona Server for MongoDB. Encrypting traffic ensures that no one can “sniff” sensitive data on the network.

The carbon footprint of a large rack mounted server is order-of-magnitude a ton of carbon a year. 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.
