Multi-tenant and High-Availability
Hi,
In installation guide of Pega 7, it says we need to choose between standard edition and Multi-tenant edition, but in the multi-tenant documentation it says
"If you select the multitenancy option and the installation or upgrade is complete, the Pega 7 Platform instance cannot be reset to perform as a standard Pega 7 Platform or a high-availability instance."
Is this an error or is it impossible to have a multi-tenant environment in a high-availability cluster ? I would say we can, but it is important for me to be sure.
Thanks for your help

You should be able to have a multi-tenant system with more than one node. Multi-tenant and multi-node (with High Availability) are two different and independent things.
Multi-tenant means having more than one distinct set of rules and data (one for each tenant) with shared resources. One tenant cannot access any of the rules or data from another tenant, and even has a distinct URL. Each tenant has a Tenant Administrator, but that Tenant Administrator has no access to anything belonging to another tenant. Tenant Admins are also unable to access High Availability functionality.
Multi-node is simply having more than one node. A multi-node system can be configured to have High Availability, regardless of whether or not it's Multi-tenant. It is the System Administrator that handles the responsibility of maintaining the High Availability functionality.

The idea for multi node and multi tenant environment is different. The statement that you have mentioned, it clearly states that you have to decide if you want multi node (Standard) or multitenant environment based on your usage. High available systems works on different nodes. In multitenant environment there is only one node and practically this node can be used for development.

HI,
What you say makes sense, I got confused by the sentence in the pega documentation, but I agree with you, should be two different things. Thanks for your confirmation.
