Hardware requirements (2 gateways and 300-500 sensors)


I am trying to figure out what VPS should I take for basic setup. I have 2 gateways and will have between 300-500 sensors. This will put anywhere between 60-100 frames per minute.

On my test I have 3 gateways and around 30 sensors with around 6 frames per minute. It is 1 vCPU and only 2 GB of RAM and server load is less than 0.1

Should for this higher load scenario 2 vCPUs and 8 GB RAM be enough?

Are there any info on this anywhere, it is impossible to find it for me. Any help is welcome.

one VM(virtual machine) with one socket 2 core CPU, with 40GB HDD, with 768MB RAM is enough for us.
