云计算
云计算作为一种技术可以用两个部分的技术解释即:前端和后端。前端是在客户端或者更具体地说任何客户端可以看到的是前端。然而,后端系统的“云”一节。是这个后端云计算软件架构和硬件需要(Antonopoulos & Gillam,2010)。
现在云计算可以包括任何程序从数据处理程序视频游戏或看电影。每个应用程序或软件使用将拥有自己的专用的在自己的专用服务器。这个服务器是遵循指令的客户,监控服务器流量等,这是确保由服务器只有遵循规则被称为“协议”,并使用组特殊的软件称为“中间件”。中间件软件,确保网络电脑工作顺利和有效(Antonopoulos & Gillam,2010)。
例如我们打开配置文件在Facebook上,我们看到在我们的屏幕是前端,然而当我们输入密码在Facebook上检索关于我们的信息,我们的朋友在物业时间等。这种数据存储在服务器上的Facebook或其他服务器带来的Facebook,因此,这些服务器然后给前端的信息和你的资料。
这是云计算的功能,一切在于虚拟设置,可以在任何时候从任何地方访问。
Cloud computing
Cloud computing as a technology can be explained in two sections of the technology namely: front end and back end. Front end is the end at the customer’s side or more specifically whatever the client can see is front end. However, back end is the “cloud” section of the system. It is this back end in cloud computing that has software architecture and hardware needed (Antonopoulos & Gillam, 2010).
Now cloud computing can include any program right from data processing programs to video games or watching movies. Every application or software to be used will have its own dedicated place at its own dedicated server. It is this server that follows instructions of clients, monitors traffic on servers etc, this is ensured by the server only by following rules known as “Protocols” and using special set of software known as “Middleware”. Middleware is software that ensures that networked computers work smoothly and efficiently (Antonopoulos & Gillam, 2010).
For example we open our profile on Facebook, what we see on our screen is the front end, however when we enter our password on Facebook it retrieves information about us, our friends etc at realty time. This data is stored on servers of Facebook or other servers brought by Facebook, thus it is these servers then who give information to the front end and your profile comes up.
This is how Cloud Computing functions where everything lies in virtual setup and can be accessed from anywhere at any time.
