vRealize Automation Reference Architecture Guide The vRealize Automation Reference Architecture Guide describes the structure and configuration of typical vRealize Automation deployments. In addition, it provides information about high availability, scalability and deployment profiles. Intended Audience This information is intended for anyone who wants to configure and manage vRealize Automation.
Reference Architecture 6 VMware, Inc.
Updated Information This Reference Architecture is updated with each release of the product or when necessary. This table provides the update history of the Reference Architecture. Revision Description 002381-01 Made several updates relative to feedback from support. 002381-00 Initial release. VMware, Inc.
Reference Architecture 8 VMware, Inc.
Initial Deployment and Configuration Recommendations 1 Deploy and configure all VMware vRealize Automation components in accordance with VMware recommendations. Keep your vRealize Automation, vRealize Business for Cloud, and vRealize Orchestrator in the same time zone with their clocks synchronized. Install vRealize Automation, vRealize Business for Cloud, and vRealize Orchestrator on the same management cluster.
Reference Architecture 10 VMware, Inc.
vRealize Automation Deployment 2 Use the VMware resource recommendations as a starting point for vRealize Automation deployment planning. After initial testing and deployment to production, continue to monitor performance and allocate additional resources if necessary, as described in Chapter 4, “vRealize Automation Scalability,” on page 17.
Reference Architecture For more information about changing the default MSDTC ports, see the Microsoft Knowledge Base article Configuring Microsoft Distributed Transaction Coordinator (DTC) to work through a firewall available at https://support.microsoft.com/en-us/kb/250367. vRealize Automation supports SQL AlwaysON groups only with Microsoft SQL Server 2016. When installing SQL Server 2016, the database must be created in 100 mode.
Chapter 2 vRealize Automation Deployment For best product performance, review and implement configuration guidelines described in the vRealize Automation Coding Design Guide prior to importing vRealize Orchestrator content into production deployments. VMware, Inc.
Reference Architecture 14 VMware, Inc.
vRealize Business for Cloud Deployment Considerations 3 Deploy vRealize Business for Cloud, formerly known as vRealize Business Standard Edition, in accordance with VMware guidelines. Load Balancer Considerations Load balancing is not supported for data collection connections. For more information, see Chapter 4, “vRealize Automation Scalability,” on page 17. In the vRealize Business for Cloud appliance for UI and API client connections, you can use the vRealize Automation load balancer. VMware, Inc.
Reference Architecture 16 VMware, Inc.
vRealize Automation Scalability 4 Consider all applicable scalability factors when configuring your vRealize Automation system. Users The vRealize Automation appliance is configured for syncing less than 100,000 users. If your system contains more users, you may need to add memory to vRealize Automation Directories Management. For detailed information on adding memory to Directories Management, see "Add Memory to Directories Management" in Configuring vRealize Automation.
Reference Architecture Performance Analysis and Tuning As the number of resources collecting data increases, data collection completion times might become longer than the interval between data collection intervals, particularly for state data collection. To determine whether data collection for a compute resource or endpoint is completing in time or is being queued, see the Data Collection page.
Chapter 4 vRealize Automation Scalability 2 Locate the binding name and readerQuotas lines in the file. Note Do not confuse these two lines with the similar lines that contain the following string: binding name = "ProvisionServiceBinding". 3 Replace the number values assigned to the maxReceivedMessageSize and maxStringContentLength attributes with a larger value.
Reference Architecture 20 VMware, Inc.
vRealize Business for Cloud Scalability 5 Configure your vRealize Business for Cloud installation for scalability in accordance with VMware guidelines. vRealize Business for Cloud can scale up to 20,000 virtual machines across four VMware vCenter Server instances. The first synchronization of the inventory data collection takes approximately three hours to synchronize 20,000 virtual machines across three VMwarevCenter Server instances.
Reference Architecture 22 VMware, Inc.
vRealize Automation High Availability Configuration Considerations 6 If you require maximum system robustness, configure your vRealize Automation system for high availability in accordance with VMware guidelines. vRealize Automation Appliance The vRealize Automation appliance supports active-active high availability for all components except the appliance database. To enable high availability for these appliances, place them under a load balancer.
Reference Architecture Infrastructure Manager Service The manager service component supports active-passive high availability. To enable high availability for this component, place two manager services under a load balancer. Because two manager services cannot be active simultaneously, disable the passive manager service in the cluster and stop the Windows service. If the active manager service fails, stop the Windows service, if it is not already stopped under the load balancer.
vRealize Business for Cloud High Availability Considerations 7 Use the VMware vSphere HA feature for the vRealize Business for Cloud Edition appliance. To configure the VMware vSphere HA feature on the VMware ESXi host, see the vCenter Server and Host Management documentation. VMware, Inc.
