二、什么是云计算

What is Cloud Computing?

Cloud computing means accessing IT resource as a Service.

You can get the IT resources like infrastructure, Server and Software as a Service which means you just has to use the resource and pay for it .

This is exactly like our power bill.We use the power and pay the bill.

Similarly, there are vendors who provide the services to consume.

• Windows, Linux or Mac Machine.
• Internet, Firewall or Proxy.
• Customized Hardware Spec Machine.
• System with Software Installed.
• Ready to use Software Applications.

All the above services are accessed via the internet so it is called as Cloud Computing.

Major benefit of Cloud Computing that you can access your data and application from anywhere.

With Cloud Computing, We do not need to maintain any hardware or man power for Maintenance.

We just have to use the IT resources and Pay for the usage.

云计算意味将IT资源当作一种服务访问。

你可以获得基础设施，服务和软件服务等IT资源，这意味着你只需要使用这些资源并付费。

这个和我们的电费账单一样，我们用电然后付费。

类似的，也有提供服务来消费的供应商。

以上的所有服务都可以通过网络访问，因此被称为云计算。

云计算最主要的好处是你可以在任何地方访问你的数据。

有了云计算，我们不需要任何硬件的运维和人力的运维。

我们只是使用IT资源并为此付费。

三、云服务模型类型

Types of Cloud Service Models

Cloud Service model means giving access to IT services in three ways:

1.Software as a Services(Saas)

2.Platform as a Services(Paas)

One good thing about SaaS that everyone get to use the high quality same software at ditonfferent price levels.

我们可以通过软件即服务在任何地方访问软件。

供应商将在需要的时候安装，运维，升级或者修补软件。

你只需要支付每月的费用用来访问软件。

软件即服务有一个好处，每个人可以在不同价格的水平上想用很高的软件使用质量。

Platform as a Services - 平台即服务
