4.4 vSphere Cluster Design
vSphere clusters are physical groups of ESXi hosts that are grouped together to create a pool of resources. Service providers can design their cluster topology to meet their needs based on factors such as costs, security, and manageability.
Typically, there are three types of clusters that service providers deploy:
• Management – Leveraged to host all management components.
• Edge services – Used to host all networking services appliances.
• Resource/payload – Where the end customer virtual workloads are located.
