Does Aura mean Gibibytes or Gigabytes when you state GB on your memory sizing for instances?
We use the term gigabyte (GB), as the binary (base 2) numeric scale for multiple bytes, and when we say GB we mean 1024 MB, as defined by the Joint Electronic Device Engineering Council (JEDEC). This unit of measurement is also known as a gibibyte (GiB).
How is the memory allocated ?
Each Neo4j Aura instance is carefully calibrated to allocate the memory resources as a mix of JVM overhead, native memory and Java heap to be made available to the database without you having to tune any of this.
What does a CPU resource mean exactly and how can I compare this to a physical server single CPU performance?
Neo4j Aura runs on container technology and this allows for the service to allocate dedicated CPU resources to individual databases while allowing databases to burst shared CPU when needed. A CPU is in this case a vCPU or CPU thread.
Why should you not compare Aura instances with a single physical server ?
Comparisons of CPU in a physical server to the minimum dedicated CPU on Neo4j Aura is not relevant because it misses the real value of the service to our customers, including:
