* N machines to run the desired number of {zdm-proxy} instances:
** You will need one machine for each {zdm-proxy} instance.
** Requirements for each {zdm-proxy} instance:
*** Ubuntu Linux 20.04 or newer, RedHat Family Linux 7 or newer
*** Ubuntu Linux 20.04 or 22.04, RedHat Family Linux 7 or newer
*** 4 vCPUs
*** 8GB RAM
*** 20GB - 100GB root volume
*** Equivalent to AWS `c5.xlarge` / GCP `e2-standard-4` / Azure `A4 v2`
* One machine for the jumphost, which is typically also used as Ansible Control Host and to run the monitoring stack (Prometheus + Grafana):
** The most common option is using a single machine for all these functions, but you could split these functions across different machines if you prefer.
** Requirements:
*** Ubuntu Linux 20.04 or newer, RedHat Family Linux 7 or newer
*** Ubuntu Linux 20.04 or 22.04, RedHat Family Linux 7 or newer
*** 8 vCPUs
*** 16GB RAM
*** 200GB - 500GB storage (depending on the amount of metrics history that you wish to retain)
*** Equivalent to AWS `c5.2xlarge` / GCP `e2-standard-8` / Azure `A8 v2`
* 1-M machines to run either {dsbulk-migrator} or {cstar-data-migrator}.
** It's recommended that you start with at least one VM with 16 vCPUs and 64GB RAM and a minimum of 200GB storage. Depending on the total amount of data that is planned for migration, more than one VM may be needed.
** Requirements:
*** Ubuntu Linux 20.04 or newer, RedHat Family Linux 7 or newer
*** Ubuntu Linux 20.04 or 22.04, RedHat Family Linux 7 or newer
*** 16 vCPUs
*** 64GB RAM
*** 200GB - 2TB storage (if you use dsbulk-migrator to unload multiple terabytes of data from origin, then load into target, you may need to consider more space to accommodate the data that needs to be staged)
