无论是远程访问还是数据备份；有很多可用的云服务。随着云的出现，传统的工作方式正在发生变化。SaaS 或软件即服务(Software as a Service)是流行的云服务形式之一。
软件即服务 (SaaS)
在我们查看 SaaS 的一些示例之前，(SaaS)这里有一些关于 SaaS 应该提供什么的一般规则：
- 云公司为您提供根据您的需要工作的软件；
- 除随软件提供的自定义选项外，您不应尝试以任何方式更改软件功能；
- 您可能需要也可能不需要将软件下载到本地计算机，但您使用该软件，结果存储在云端（例如：备份；同步；数据收集等）
- 软件(Software)即服务(Service)应该足够快以向人们提供服务。例如，如果它是存储软件，它应该能够在需要时提供空间。同样，当对空间的需求减少时，软件应该释放额外的空间。
- 您应该只为您使用的服务付费；不应该有明确的固定费用。
牢记上述内容，让我们看看SaaS（软件(Software)即服务(Service)）的一些示例：云服务的基本和最流行的形式。
办公网络应用
我能想到的软件(Software)即服务(Service)( SaaS )的最佳示例是 Microsoft 的Office Web Apps。您可以在任何地方使用该软件。
如果您使用OneDrive登录并使用该软件，请不要混淆OneDrive和Office Web Apps。后者与OneDrive不同，后者是一个平台（又是云服务），为您提供远程空间，以便您可以从任何地方访问您的文档。我们将在一分钟内详细了解OneDrive。
Office Web Apps允许您创建存储在OneDrive上的文件。您必须将文件存储在某个地方，OneDrive可以轻松融入其中。因此(Hence)，许多人认为Office Web Apps是OneDrive的一部分，反之亦然。您可以实时编辑和协作处理此类文件。你们中的一些人可能已经在使用这些服务，尤其是MS Word即服务(Service)。它们提供了几乎所有必要的功能来满足您的需求。

ThinkFree Office在类似的线路上也是一项很好的服务。它还为您提供了云中的可用空间来存储您的文档，并具有足够的功能让您创建一个好的文档、电子表格或演示文稿。
Mozy：软件即服务
Mozy是云备份服务提供商领域的知名品牌。作为最初的SaaS提供商之一，Mozy也是软件(Software)即服务(Service)( SaaS ) 的一个很好的例子。但是，在这种情况下，您必须将软件下载到您的机器上。但是，只要您记住您的登录凭据，您就可以使用任何其他计算机上的备份集。
通常，人们设置软件并忘记它。这使他们也像我一样忘记了登录凭据。您可能希望使用最好的密码管理器(best password managers)之一使用浏览器直接登录到Mozy 。在那里您可以访问您的备份数据。
我在上一段中偏离了主要主题，但如果您打算使用浏览器访问Mozy或必须重新安装(Mozy)Mozy ，请务必记住您的登录凭据，这一点很重要。在这种情况下，密码管理器会派上用场。
无论如何，Mozy提供 2GB 的免费存储空间。您可以在mozy.com/free获得它。随着您的存储需求增加，Mozy会自动为您分配更多空间（如果您已经设置了信用卡）。当您的存储需求减少时，Mozy将释放不需要的空间，这样您就无需为此付费。仅使用免费的 2GB 空间，您无需设置您的卡信息。同样，您也只能获得所需的空间。并不是说你注册的时候，Mozy会以你的名义分开 2GB。您只能使用备份集占用的空间。
OneDrive 同步
这也有点像Mozy，但更流行且更易于设置。您还必须在此处将软件下载到本地计算机。该软件设置需要备份或同步的所有文件夹。设置后，您很容易忘记它，因为它会在文件添加到OneDrive文件夹或更改时继续同步文件。
其他此类SaaS包括(SaaS)Google Drive和Dropbox云。最近，他们的移动同行还推出了一项功能，他们可以备份您使用手机点击的所有图片。您可以随时禁用该服务。我在Dropbox(Dropbox)上使用该服务，因为它会自动将图像复制到我电脑上的Dropbox文件夹中(Dropbox)

猎物
在我们结束之前，我想提一下Prey，这是一款跟踪您的笔记本电脑、平板电脑或手机的软件。这也属于SaaS的范畴，因为您必须安装一个不断将屏幕截图和其他数据发送到云的软件。您可以通过登录您的Prey帐户使用任何计算机查看该数据。它已经帮助很多人找回被盗的笔记本电脑和手机，所以我推荐它。阅读TheWindowsClub 上的Prey Anti Theft 软件评论
以上是软件(Software)即服务(Service)的一些示例。这些天来，这样的服务并不缺乏。它们在云计算中非常丰富且最受欢迎。如果您正在使用，请与我们分享。

Software as a Service (SaaS) : Examples and advantages
Be it for remotе access or a backup of your data; there are plenty of cloud sеrvices available. With the cloud at the front, traditional ways of working are changing. SaaЅ or Software as a Service is one of the popular forms of cloud services.
Software as a Service (SaaS)
Before we check out some examples of SaaS, here are some general rules about what a SaaS should offer:
- The cloud company offers you software for working per your need;
- You should not attempt to change the software functioning in any method except for the customization options provided with the software;
- You may or may not have to download the software to your local computer but you use the software, and the results are stored in to the cloud (example: backup; sync; data collection, etc.)
- Software as a Service should be fast enough to provide services to people. For example, if it is storage software, it should be able to provide space as and when needed. Similarly, when the need for space reduces, the software should release extra space.
- You should be billed only for the service you use; there should not be a definite flat fee.
Keeping the above in mind, let us check out some examples of SaaS (Software as a Service): the basic and most popular form of cloud services.
Office Web Apps
The best example of Software as a Service (SaaS) I could think of is Microsoft’s Office Web Apps. You can use this software from anywhere.
If you use OneDrive to log in and use the software, do not confuse between OneDrive and Office Web Apps. The latter is different from OneDrive, which is a platform (a cloud service again) that offers you remote space so that you can access your documents from anywhere. We will read about OneDrive in detail in a minute.
Office Web Apps allow you to create files stored on OneDrive. You have to store the files somewhere, and OneDrive easily blends in there. Hence many confuse that Office Web Apps are part of OneDrive or vice versa. You can edit and collaborate on such files in real-time. Some of you might already be using those services, especially MS Word as a Service. They provide almost all the features necessary to suit your needs.

ThinkFree Office too is a good service on similar lines. It too offers you free space in the cloud to store your documents and has enough features to let you create a good document, spreadsheet, or presentation.
Mozy: Software as a Service
Mozy is a well-known name in the field of cloud backup service providers. One of the initial SaaS providers, Mozy is also a good example of Software as a Service (SaaS). However, in this case, you have to download software to your machine. You can – however – use the backup sets from any other computer as long as you remember your login credentials.
Usually, people set up the software and forget it. That makes them forget the login credentials too as I did. You might want to use one of the best password managers to log in direct to Mozy using a browser. There you can access your backed-up data.
I deviated a bit from the main topic in the above paragraph, but it was important to tell you to keep your login credentials in mind if you intend to access Mozy using a browser or if you have to reinstall Mozy. A password manager comes in handy in such a case.
Anyway, Mozy offers 2GB of storage space as free. You can get it here at mozy.com/free. As your storage demand increases, Mozy will automatically allot you more space (if you have your credit card set up already). As and when your storage demand reduces, Mozy will free up unwanted space so that you are not billed for it. For using the free 2GB space only, you need not set up your card information. In that too, you are given only as much space as you require. It is not that when you sign up, Mozy will set apart 2GB in your name. You get to use only as much space as your backup sets occupy.
OneDrive Sync
This is also somewhat like Mozy but more popular and easier to set up. You have to download a software to your local machine here as well. The software sets up which all folders need to be backed up or rather, synced. Once you set it, you can easily forget it as it will keep on syncing files as they add up to the OneDrive folder or as they change.
Other SaaS of this type includes Google Drive and Dropbox cloud. Lately, their mobile counterparts have also introduced a feature wherein they back up all the pictures you click using your mobile phone. You may disable the service whenever you want. I use the service on Dropbox as it copies images automatically to the Dropbox folder on my computer

Prey
Before we wind up, I would like to mention Prey, a software that tracks your laptop, tablet, or phone. This, too, comes into the category of SaaS as you have to install a software that keeps on sending screenshots and other data to the cloud. You can view that data using any computer by logging into your Prey account. It has helped many people recover their stolen laptops and phones, so I recommend it.

The above were some of the examples of Software as a Service. These days, there is no dearth of such services. They are abundant and most popular in cloud computing. If you are using one, please share it with us.
