OS Requirement for Cortex XSOAR engine deployment

[DP696]

Hi,

In one of the XSOAR documentation its mentioned "For all Linux deployments except RHEL 7.x (for example Ubuntu, CentOS, etc.). Automatically installs Docker, downloads Docker images, enables remote engine upgrade, and allows installation of multiple engines on the same machine. For RHEL 7.x, see Install Docker Distribution for Red Hat on Cortex XSOAR."

Want to confirm whether RHEL 7.x version supports multiple engines on the same machine.

This is operating system independent. When building the Engine installer, there is a tick box 'allow multiple engines'. This has to be done the first time Engine installed. It cannot be converted later. You can then build a second engine installer the same way and run the install on the same engine host. XSOAR will see this as a separate engines. Docker containers are managed under the hood and may increase the number of idle containers awaiting XSOAR.

Note: this is most commonly used in Multi-Tenant edition XSOAR - where one engine host can be logically attached multiple tenants. There is no performance advantage doing this single tenant edition version of XSOAR. You are better off more engines if this is for scale. To get more from one engine host you can increase the minimum watermark for idle docker containers, so there is less wait time spinning up new containers when there is a spike in workloads.
Also installing multiple engines on one host is useful in dev to replicate/test load-balancing group configs without needing two hosts. Hope this all helps.

Hi,

In our case we need to install one engine from dev and one engine from prod environment on the same machine. Hence we have to select "allow multiple engines" when building installer file on both the environment, correct?
