1
When you're deploying a cloud -based application, you also need to consider who will be accessing that application and from where.
2
If you're creating an application that anyone on the internet would need to access,
3
then you would probably want to include it in a public cloud so that everyone can gain access.
4
But if you're building out a cloud -based application that is for internal use only,
5
you may want to deploy this to your own virtualized local data center where you have a private cloud.
6
organizations, we often use both of these.
7
And we need a hybrid configuration of both public and private clouds for all of these applications.
8
One type of cloud model is software as a service, or SAS.
9
This is commonly associated with software that is on demand.
10
You have a login screen in your browser, you log in, and now you have access to the application.
11
Someone else has written the application, someone else manages the application, your data is stored somewhere within that application,
12
and you don't have to do anything else to be able to use that particular app.
13
You don't have a local installation of software, manage or upgrade any of the software itself.
14
Instead, you simply log in and use the app.
15
This allows for centralized management of the application and the data that you're putting into the application,
16
which means everything is being stored on a third party cloud platform.
17
This is a complete application offering, and you don't have to do any type of development work to be able to use that app.
18
A good example of software as a service would be an app like Google Mail or Office 365, where you simply log in and use the app.
19
There may be times when you would like to build your own application and deploy and manage your own data,
20
and all you really need are the computing resources to be able to run that application.
21
In that model, you want to use Infrastructure as a Service, or IAAS.
22
Sometimes you'll see this referred to as Hardware as a Service,
23
or HAAS, because you're effectively using hardware in the cloud and then using your own software on top of that.
24
This means that you would be responsible for installing your software and managing all of the data associated with that software.
25
If the software needs to be upgraded, you would be the one to upgrade it on your infrastructure as a service model.
26
The application that you're using and the data that you're putting into that application is still in the cloud.
27
But you have much more control over the access and security of that data when you're using infrastructure as a service.
28
A good example of infrastructure as a service is with web service providers, where you can buy time on a particular web server,
29
and they make that server available to everyone on the internet.
30
A middle ground between software as a service and infrastructure as a service is Platform as a Service, or PAAS.
31
This is still in the cloud, but you're the one who manages all of the development efforts to customize the application to your specifications.
32
The cloud provider gives you all of the tools necessary to build this particular app.
33
You can think of this as a series of building blocks provided by the Platform as a Service infrastructure,
34
filled out those blocks to create your own application.
35
The underlying engine that runs the application is the responsibility of the Platform as a Service provider.
36
And your responsibility is to build and maintain the apps that are running in Platform as a Service.
37
A good example of a Platform as a Service infrastructure would be something like Salesforce .com,
38
where they give you all of the tools necessary to create a customized application running on the Salesforce .com platform.
39
Here's an example of a cloud responsibility matrix that you might find with any cloud service provider.
40
In this chart, I've separated out software as a service, platform as a service, infrastructure as a service, and then an on -prem device that you would manage yourself.
41
Obviously, with on -prem, everything from the data to the applications to the physical data center are all the responsibility of the customer.
42
But with infrastructure as a service, you have the physical data center, the physical network, physical hosts, all provided by the cloud provider.
43
And then you handle all of the other pieces of that particular application.
44
With Platform as a Service, you can see that network controls,
45
applications, and the identity and directory infrastructure may be shared between the customer and the cloud provider.
46
But you'd still be responsible for the accounts, devices, and the information and data.
47
With Software as a Service, much more of these are provided by the provider themselves.
48
Everything associated with the applications is clearly in the responsibility of the provider.
49
Everything above that would still be the responsibility of the customer.
50
So depending on the type of infrastructure you want, and the type of responsibility that you're willing to take on,
51
you'll need to pick the right cloud model for your application deployment.

✨ 推荐视频
为什么要与这个视频练习口语?
在当今数字化的时代,了解云计算的基本概念非常重要。本视频的内容适合那些希望提升英语口语能力的学习者,尤其是在技术领域的应用。通过跟随视频中的讲解,学习者不仅能掌握云服务的不同模型,如软件即服务、平台即服务和基础设施即服务,还能在专业场景下提高英语发音。与此视频进行口语练习有助于熟悉相关术语,增强表达能力,从而在面试或职场中更自信地讨论云计算主题。提高英语发音的同时,学习者将如何在不同语境中灵活使用技术词汇。
语法与表达方式分析
在视频中,讲者使用了一些关键的表达结构,以下是三到五个重要的语法结构及其应用:
- When you're deploying a cloud-based application - 这种从句结构可以帮助学习者理解条件句的使用,同时也能学会如何描述流程。
- If you're creating an application that anyone on the internet would need to access - 这个句子引入了假设条件,适合练习句型转换和条件句的使用。
- Instead, you simply log in and use the app - “instead”一词的使用强调了替代关系,有助于学习者理解如何在交流中进行对比和说明。
- This allows for centralized management - 学习动词允许的不同用法及其搭配,可以帮助学习者在表达能力上更上一层楼。
常见发音陷阱
语音发音对信息的准确传达至关重要。视频中有几个容易导致混淆的单词和重音,学习者应特别注意:
- Infrastructure - 注意元音的发音,确保每个音节听起来清晰。
- Applications - 强调音节,使得每个部分的发音都能得到清晰传递。
- Access - 注意“a”的发音,在不同的口音中可能会有所不同,练习时要确认正确的发音。
- Service - 这里的重音位置及variants可以导致发音偏差,学习者可以通过跟读视频进行矫正。
运用这些发音技巧,配合视频内容的shadow speak,学习者可以有效地提高英语发音,增强交流能力。通过模仿并加以练习,您会发现与专业人士交流时更加自然流畅。
什么是跟读法?
跟读法 (Shadowing) 是一种有科学依据的语言学习技巧,最初开发用于专业口译员的培训,并由多语言者Alexander Arguelles博士普及。这个方法简单而强大:您在听英语母语原声的同时立即大声重复——就像是一个延迟1-2秒紧跟说话者的影子。与被动听力或语法练习不同,跟读法强迫您的大脑和口腔肌肉同时处理并模仿真实的讲话模式。研究表明它能显着提高发音准确性,语调,节奏,连读,听力理解和口语流利度——使其成为雅思口语备考和真实英语交流最有效的方法之一。
