This chapter briefly describes the necessary basic environment configurations of ZStack Private Cloud.
A cloud computing environment is a vitally basic IT infrastructure in a company. Before you install ZStack, make sure that you read carefully and meet configuration requirements to make full preparations for a basic hardware and software environment. Inappropriate environment configurations may lead to failures of the subsequent Private Cloud environment deployment, or abnormalities of the cloud when you use the cloud.
A typical Private Cloud environment is built on a small data center. This environment consists of two parts: multiple servers with different features and two independent network environments.
Specifically, two out of the above multiple servers can serve as a ZStack management node and a backup storage, while rest of the servers can serve as physical hosts on which VM instances run. In a small data center, a management node and a backup storage can share one server. In a large-scale physical environment, multiple management nodes are configured to provide high availabilities while multiple backup storages are configured to extend storage capacities and the throughput rate.
Each server can connect to the management network and the data network. Specifically, the data network can reach the Internet via a firewall. The management network is a network where a management node manages hosts, VM instances, volumes, and other resources. The data network is a network where VM instances provide data services.
