Medium Environment with High Availability (HA)

In this mode, the following iAutomate servers are deployed:

  • Web Server: This server hosts the Web User Interface
  • Application Server : This server hosts the Application components.
  • Advanced AI Server: This server hosts iScrape, iKnowledge, and Advanced iKnowledge components
  • Database Server: This server hosts the SQL Server database, which is the main transactional database of iAutomate
  • MongoDB : This server hosts the Document Storage Database (MongoDB).
  • Solr: This server hosts the Indexer (Solr)

The following table describes the hardware and software requirements for this installation.

Note:
The installer needs to be run on individual servers that include Web Component, Base Component, and Advance AI Component server. If Advanced AI components like iKnowledge, Advanced Knowledge and iScrape are not required, only Web Server, Application Server and Database server will be required.
Note:
Alternate Database options:
  1. AWS Relational Database Service (RDS)
  2. GCP SQL Server 2017 PaaS service
Note:
- For Document Storage, if *MongoDB must be made available in HA, then 3 servers will have to be provided as per the best practices. Alternately, MongoDB as a service can be used from AWS and GCP marketplace.

For Indexer, if Solr has to be made available in HA, then 5 servers will have to be provided as per the best practices

Note:
Ansible CLI Wrapper Component install on Ansible CLI server, it can be installed from any server.
