The following table outlines the minimum recommended production server specifications which can be followed for both on premise and cloud deployments:

= Network
| Network Interconnect | In a multi server deployment data will be passed around via TCP/IP networking. At least a 1G network is recommended. |

= Details
These are minimum recommendations and in general the system will perform better with more hardware:
* More CPU cores and servers will improve query processing response time.
* More memory will allow the system to cache more data blocks in memory. We have users running system with anywhere from 64G RAM to 512 G RAM for UM and 32 to 64 G RAM for PM.
* Faster network will allow data to flow faster between UM and PM nodes.
* SSD's may be used, however the system is optimized towards block streaming which may perform well enough with HDD's for lower cost.
* Where it is an option, it is recommended to use bare metal servers for additional performance since ColumnStore will fully consume CPU cores and memory.
* In general it makes more sense to use a higher core count / higher memory server for single server or 2 server combined deployments.
* In a deployment with multiple UM nodes the system will round robin requests from the mysqld handling the query to any ExeMgr in the cluster for load balancing. A higher bandwidth network such as 10g or 40g will be of benefit for large result set queries.

== AWS instance sizes
For AWS our own internal testing generally uses m4.4xlarge instance types as a cost effective middle ground. The R4.8xlarge has also been tested and performs about twice as fast for about twice the price.
