先决条件 – 虚拟主机及其类型以及如何选择虚拟主机服务器和网络域?
1. 云主机：
云托管是网络托管市场上的高级计划之一。这里的网站托管在一组或一组服务器上，许多服务器和机器作为单个实体同步工作。云托管允许使用云计算设施创建计算资源。它具有良好的可扩展性和灵活性，因此可以根据需要轻松增加或减少资源。这对高流量的网站很有好处。它的速度和灵活性使其成为网络托管的首选。
云托管的优点：
- 按需资源——按时付款。
- 高可用性 – 可靠。
- 更好的可扩展性——灵活。
- 恢复丢失的数据。
云托管的缺点：
- 需要高级云知识。
- 平台依赖——云供应商协作
- 对用户使用服务的有限控制
2. 共享主机：
共享托管是网络托管市场上最常见的计划之一，因为托管价格非常低。这里一台服务器托管多个网站。这就是所有网站共享磁盘空间、存储和带宽等公共资源的原因。它具有成本效益，特别是对于流量较小的网站，因为托管服务提供商处理所有技术任务，并且易于使用。但有时网站加载时间可能会很慢，因为它是共享的，也不适合流量大的情况。
共享主机的优点：
- 定价结构——便宜。
- 易于使用 – 初学者友好。
- 管理良好的安全性、升级和维护。
- 无行政责任
共享主机的缺点：
- 共享时加载时间缓慢。
- 由于共享，安全性受到影响。
- 在人满为患期间缺乏服务器控制。
- 不提供良好的可扩展性
云主机和共享主机的区别：
