Some of the most important elements include: No single point of failure (SPOF): You must eliminate any SPOF in the database environment, including any potential for an SPOF in physical or virtual hardware. Load balancing: Traffic is distributed across multiple servers to prevent any one component from becoming overloaded.

Open source databases provide great foundations for high availability — without the pitfalls of vendor lock-in that can come with proprietary software. However, open source software doesn’t typically include built-in HA solutions. This blog provides links to such architectures — for MySQL and PostgreSQL software.

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.

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.
