ESXi host design and configuration considerations for a cloud
The following factors need to be considered in your host design and configuration of the cloud:
Domain Name Service (DNS): DNS must be configured for both ways: forward and reverse lookup.
Network Time Protocol (NTP): An NTP should be configured across all the ESXi hosts, and we should have NTP synchronization in place, along with VMware vCenter Server. This will help us achieve consistency across all infrastructure-virtualized servers.
Disk considerations: VMware ESXi 5.5 and later versions support the following disk type for booth such as the local disk, USB/SD, SAN, and even from stateless. The majority of consumers use stateless for the purpose of saving costs and administration effort, though VMware recommends that you implement VMware ESXi on SD.
Installation considerations: It is worth considering using shared volume in your design, even though VMware recommends using NFS data stores.
