根据Tech Pro Research进行的一项调查，68% 的互联网用户(Internet)知道什么是混合云(Hybrid Cloud)。然而，样本量只有 138 人，构成了对信息技术(Information Technology)领域感兴趣的人。我不同意 65% 的 IT 人员了解混合云，因为他们中的大多数人尚未了解云计算(cloud computing)的所有概念和事实（当我们考虑来自世界各地的 IT 人员时）。在许多国家，由于一个或多个原因，企业不采用云计算。主要原因之一是对公共云缺乏信任。
可能这些国家/地区的个人了解并使用云计算（OneDrive、Google Drive等）。但亚马逊(Amazon)、Azure等几乎找不到来自这些国家的订阅者。原因(Reason)？缺乏(Lack)对云计算概念的正确理解，再次担心数据被盗和数据丢失。
什么是混合云
有公有云，也有私有云。介于两者之间的是混合(Hybrid)云。
OneDrive、Google Drive等是人们共享相同服务器的公共云。云的特点是它可以根据需要增加和减少服务。这同样适用于Azure、Amazon和Ubuntu云。您会同意OneDrive和Google Drive （以及(Google Drive)Mozy等类似的存储服务）等更受欢迎，因为它们适合商业机构和个人。我的整个Office都存储在OneDrive上。自从微软以(Microsoft)SkyDrive的名义免费提供高达 25GB 的容量时，我就一直在使用它。因此(Thus)，我可以从世界任何地方访问它。
无论如何，回到什么是混合云(Cloud)，我们首先要了解公共云和私有云。您看到的以OneDrive、Google Drive、Canonical等形式出现的云是最流行的公共云。它们之所以被称为公共，是因为数据存储在相同的服务器上，而与此人的居住地或存储的内容无关。如果服务提供商可以查看存储的数据（这再次成为云使用的威慑），则存在担忧。
换句话说，
- 任何人只需注册服务即可使用云服务
- 只需更改计划即可扩展和减少云服务
- 占用空间(Space)在云端实时提供和释放
- 没有或最少的人工干预
- 除非条款和条件中另有说明，否则云服务提供商无法查看用户存储的数据。如果他这样做，它将被归类为违反信任。
然而，看看最后一点，政府规则可以强制云提供商在用户不知情的情况下向联邦机构或其他相关机构提供有关客户的数据。因此，违反数据因素是不可行的。
(Private clouds)在存储数据方面，私有云更安全。请(Please)注意，我一直以数据存储为例，因为它更容易理解。因此，云(Cloud)计算可以是任何东西，从数据存储到提供平台即服务，用户不仅可以创建他们的程序，还可以在不同的条件下对其进行测试。
但是实施私有云是一个复杂的过程。您将需要额外的服务器，而这仅仅是开始。您需要了解云的概念和功能的 IT 管理员。然后，您将需要能够在人为干扰可以忽略不计的情况下创建和维护软件的程序员。然后，应该使组织的所有分支机构都可以访问云。最后，您必须照顾黑客等，并使云尽可能防黑客。
为了避免所有这些复杂情况，组织倾向于使用混合云。也就是说，组织的一些流程在私有云上运行，而另一些则在Azure等复杂的云上运行。
混合云定义
混合云没有明确的定义。实际上，云计算并没有明确的定义。关于云计算的标准有不同的解释。这些标准也因用户的观点而异。无论如何(Anyway)，我将尝试如下定义混合云：
“Any cloud computing service that employs use of both public and private clouds is known as hybrid cloud”.
此外，问题在于为什么要使用混合(Hybrid)云。上面我们讲了私有云，发现很复杂。混合云在自己的私有云上运行简单的流程，并使用公共云来处理复杂的流程。这样，您不仅可以减少开支，还可以减少可能阻碍或延迟您的业务流程的各种复杂情况。
虽然您可以自己构建私有云（与混合(Hybrid)云一起使用），但许多公司（例如IBM）会提供自己的工程师来通过公共云简化私有云。这再次节省了开支，同时让您无需寻找适当的专业知识来设置与任何公共云一起使用的私有云。
总结一下：
- 混合(Hybrid)云同时使用私有云和公共云
- 混合(Hybrid)云采用与公共云一起使用的本地云，以避免在编程和维护方面的高额费用
- 混合(Hybrid)云为数据和流程提供更好、更可靠的安全性，因为复杂的数据是在安全的公共云上处理的（尽管许多人仍然对这方面持怀疑态度）
云的唯一问题是各国的法律规则不同。在云计算的情况下，如果发生任何争议，适用服务提供商注册其服务的地区的规则。这就是为什么微软(Microsoft)强调全球法律法规的普遍化。如果实现这一点，它将使服务提供商和客户都更容易。
混合云(Hybrid Clouds)的优势和优势
- 本地基础设施
- 由于互联网流量，没有延迟
- 由于某些数据在本地处理，因此处理时间更快，因此与在云上处理的所有数据相比，您可以节省时间。您必须上传数据并下载结果。这需要时间
- 复杂的流程在公共云上运行，从而节省了基础设施的费用和管理
- 您可以全年使用私有云，并在需要时扩展您的公共云使用，而不是构建或扩展本地基础设施。

What is Hybrid Cloud? Defination, advantages and benefits
According to a survey conducted by Tech Pro Research, 68% оf people using the Internet know what a Hybrid Cloud is. However, the sample size was just 138 and constituted people interested in the Information Technology field. I am not inclined to agree that 65% of IT people understand hybrid clouds because most of them are yet to understand all the concepts and facts of cloud computing (when we consider IT people all from over the world). In many countries, business houses do not go for cloud computing due to one or more reasons. One of the primary reasons is the lack of trust in public clouds.
Probably, individuals in such countries understand cloud computing and use it too (OneDrive, Google Drive, etc.). But Amazon, Azure, etc. find almost no subscribers from such countries. Reason? Lack of proper understanding of cloud computing concepts and again, fear of data being stolen and loss of data.
What is Hybrid Cloud
There are public clouds and there are private clouds. In between the two, lies the Hybrid cloud.
OneDrive, Google Drive, etc. are public clouds where people share the same servers. The specialty of the cloud is that it can increase and decrease the service as and when needed. The same applies to Azure, Amazon, and Ubuntu clouds. You will agree that OneDrive and Google Drive (and similar storage services like Mozy) etc. are more popular as they fit for both business houses and individuals. My entire Office is stored on OneDrive. I am using it since the time Microsoft was offering a whopping 25GB for free under the SkyDrive name. Thus, I can access it from any part of the world.
Anyway, coming back to what is Hybrid Cloud, we have to first understand public and private clouds. The clouds that you see in the form of OneDrive, Google Drive, Canonical, etc. are the most popular public clouds. They are called public because data is stored on the same servers irrespective of where the person lives or what he or she is storing. There are concerns if the service provider can look into the data being stored (which is again a deterrent for cloud usage).
In other words,
- The cloud service can be used by anyone simply by signing up for the service
- The cloud service can be expanded and reduced simply by changing plans
- Space occupied is provided and released in real-time on the clouds
- There is no or minimal manual intervention
- Unless otherwise stated in T&C, the cloud service provider cannot look into the data being stored by the users. If he does, it will be categorized as a breach of trust.
However, looking at the last point, government rules can coerce the cloud provider to provide data about a client to the federal agencies or others related to it – without the knowledge of the user. Thus, the breach of data factor is not feasible to implement.
Private clouds are safer when it comes to storing data. Please note that I’ve been using the storage of data as an example as it is easier to understand. Cloud computing, as such, can be anything from storage of data to providing a platform as a service where users can not only create their programs but test them under different conditions.
But implementing a private cloud is a complicated process. You’ll need additional servers and that is just the beginning. You need IT admins who understand the concepts and features of the cloud. Then you would need programmers who can create and maintain software where human interference is negligible. Then, the cloud should be made accessible to all the branches of the organization. Finally, you have to take care of hackers, etc. and make the cloud as hacker-proof as possible.
To avoid all these complications, organizations tend to use hybrid clouds. That is, some of the processes of the organization run on the private cloud while others run on complicated clouds such as Azure.
Hybrid Cloud definition
There is no solid definition for hybrid clouds. Actually, there is no solid definition for cloud computing. There are different explanations that talk about the criteria of cloud computing. And these criteria too, vary based upon the perspectives of users. Anyway, I will try to define a hybrid cloud as follows:
“Any cloud computing service that employs use of both public and private clouds is known as hybrid cloud”.
Further, the question arises as to why the Hybrid cloud. We talked about the private cloud above and found that it is very complicated. A hybrid cloud runs simple processes on own private cloud and uses public clouds for complicated processes. That way, you cut down on not only expenses but also on different complications that may hinder or delay your business processes.
While you can build a private cloud (for use with a Hybrid cloud) on your own, many companies (such as IBM) provide their own engineers to streamline your private cloud with the public cloud. That again saves on expenses while relieving you from hunting for proper know-how to set up your private cloud that is used in conjunction with any public cloud.
To sum up:
- Hybrid clouds use both private and public clouds
- Hybrid clouds employ an on-premise cloud which is used with public clouds to avoid heavy expenses on programming and maintenance
- Hybrid clouds offer better, reliable safety to data and processes as the complicated data is processed on safe public clouds (though many people are still skeptical about this aspect)
The only problem with clouds is that the legal rules vary across countries. In the case of cloud computing, if any dispute arises, the rules of the area where the service providers registered their service, apply. This is why Microsoft stresses on the universalization of legal rules and regulations across the globe. It would make it easier for both service providers and clients if that is achieved.
Benefits and advantages of Hybrid Clouds
- On-premise infrastructure
- No latency due to internet traffic
- Faster processing time as some data is processed locally and thus you save time when compared to all data processed on the cloud. You have to upload data and download results. It takes time
- Complicated processes run on the public cloud so saves expenses and management of infrastructure
- You can use a private cloud all the year and extend your public cloud usage as and when required, instead of building or extending on-premises infrastructure.
