High Availability setup in API-Portal
The High Availability(HA) set up in API-Portal ensures continuous operation in cases of a fail-over scenario where up to one runnable of each kind or a whole machine becomes unavailable.
Prerequisites:
A minimum of three machines with
API-Portal set up on each of them.
Switch-off firewalls or open appropriate ports on each machine so that they can access all components on the other machines.
On installing API-Portal 9.10, the runnables are installed and are visible in the ARIS Cloud Controller (ACC). The figure below depicts a general 3-machine API-Portal setup with the runnables installed.
The figure below depicts a 3-machine HA set up for API-Portal and the distribution of the runnables there after.
Machine 2 and 3 are configured the same way. Either when the full machine goes down or the runnables zoo and elastic stop working, with the runnables on machine 2 and 3 running properly, the system is still in the operation mode.
