Hi, I’m trying to figure out is it any suggestions of RAM size and CPU cores per AS node and what is preferable way to build a cluster: having many instances with small amount of CPU/RAM on board? Or using a few but solid VM’s?
Most of this is detailed in the [deployment planning] section of the operations manual. Specifically, you should calculate your RAM and storage needs. Aerospike is very predictable in both measures - for example, every record costs 64B of metadata in the in-memory primary index. If your data is stored on SSD you will need to find out the capabilities of that drives using the ACT tool. There is data published on the site, and community contributions.
