The architecture describes how vRealize Suite products interact with each other and with systems in the data center to deliver a Software Defined Data Center (SDDC). Software Defined Data CenterThe software-defined data center (SDDC) provides different types of capabilities, with more complex features building on the underlying infrastructure. To enable all vRealize Suite features, you must perform a series of installation and configuration operations. Conceptual Design of a vRealize Suite EnvironmentTo start deploying vRealize Suite, you need only a small number of physical hosts. The best and most secure basis for scaling your environment is to distribute your hosts into management, edge, and payload clusters to establish the foundation of a deployment that can later scale to tens of thousands of VMs. vRealize Suite Products in the Management ClusterThe number of vRealize Suite products in the management cluster increases as you add capabilities. A management cluster must contain a minimum set of products. You can expand the product set when you require additional capabilities. SDDC Core InfrastructureThe SDDC core infrastructure consists of vSphere and vRealize Suite products such as vRealize Operations Manager and vRealize Log Insight for monitoring, vRealize Automation and vRealize Orchestrator for managing workflows, and vRealize Business for Cloud for costing. vRealize Suite Security ConsiderationsEach vRealize Suite product must meet security requirements. You must consider authentication and authorization for each product, ensure that certificates meet company requirements, and implement network isolation.
