Overview
The following diagram depicts a regular Active/Active deployment of Automation Suite:
Hardware |
Requirements |
---|---|
Global Traffic Manager (GTM) | Distributes traffic to your Automation Suite
multi-site deployment. The service must be highly available and
immune to any deployment site. Additionally, the GTM must be
able to configure the health check to isolate the faulty site
quickly. The GTM is not mandatory but is recommended for a quick
switchover.
When configuring the Global Traffic Manager (GTM)
for Active/Passive or Active/Active deployments, make sure
to use
/orchestrator_/api/status as the
health endpoint. This is critical for effective disaster
recovery management.
|
Load balancer | Every site needs a local load balancer that can load-balance the traffic to any node configured in the same site.
For more details, see Configuring the load balancer. |
Node |
Every site must have at least three servers, whereas agent nodes are optional. The exact number of machines depends on the machine size and overall capacity requirements. You do not need to bring the same set of nodes to each cluster. In the case of Active/Active configurations, the size of the secondary cluster can be smaller, considering that you may install only a few products. For more details, see Automation Suite Install Sizing Calculator. |
SQL database |
An external SQL server is required to store the data. For disaster recovery, you need Always On Availability Groups with a primary SQL server in Site 1 and at least one secondary physically SQL Server located in Site 2 with data sync enabled. There is also a SQL listener deployed on top of the SQL server. Both clusters are configured to use the address of the same listener. |
Objectstore |
Any files or packages uploaded to products are stored in the objectstore. For greater resilience to failure, Automation Suite deployments require an external objectstore. For effective disaster recovery, two objectstore instances are required; one instance must be situated in each data center. At any given time, only one objectstore instance must be actively used for reading and writing by both clusters. This process must be complemented by asynchronous replication to the secondary instance. |
High Availability Add-on |
For Active/Active, High Availability Add-on must be external to Automation Suite and must be installed on separate machines. A minimum of three nodes are required for both High Availability Add-on instances in each data center, configured in different clusters and synchronized (CRDB replication). To install High Availability Add-on, see the High Availability Add-on Installation Guide. For Active/Passive, High Availability Add-on is installed within the Automation Suite cluster. However, you must enable it on both clusters by providing the HAA license. For more details, see Enabling Redis High Availability Add-On for the cluster. |
Elasticsearch (optional) |
Elasticsearch is required to send the robot logs. You can configure the Elasticsearch cross-site replication as described by Elasticsearch. |
