本文将简单介绍on-premises(常简称为on-prem)的概念、优缺点、以及与云服务的对比。
On-premises,通常被简称为on-prem,指的是在公司自有物理设施内部署和管理IT基础设施。这可能包括数据中心、服务器、网络硬件、存储设备等等1。
# 一个假设的服务器配置命令
$ sudo apt update
$ sudo apt upgrade
$ sudo apt install apache2
对于on-prem部署,企业可以享有对所有硬件、软件和数据的完全控制权。这使得企业可以根据具体需求定制其IT环境2。
# 自定义配置示例
config = {
'server_ip': '192.168.1.100',
'server_port': '8080',
'database_name': 'my_database',
}
由于所有数据都存储在企业自有的硬件中,因此on-prem可以提供更高的数据安全性和隐私保护3。
On-prem部署需要大量的前期投入,包括购买和设置硬件、购买软件许可证、建设和维护数据中心等等。
{
"hardware_costs": 50000,
"software_licenses": 20000,
"data_center_maintenance": 10000
}
运行和维护on-prem部署需要一个专门的IT团队,这也会带来额外的成本4。

云服务,如AWS、Google Cloud或Azure,提供了一种替代on-prem的方法。虽然云服务可能无法提供on-prem同样级别的控制权,但它们能够降低前期投入,并提供更好的扩展性5。
选择on-prem还是云服务取决于企业的具体需求和目标。总的来说,on-prem可以提供更高的控制权和安全性,但同时也需要较高的前期投入和维护成本。
