Shadowing Practice: Cloud Models - CompTIA Network+ N10-009 - 1.3 - Learn English Speaking with Video

When you're deploying a cloud -based application, you also need to consider who will be accessing that application and from where.

If you're creating an application that anyone on the internet would need to access,

then you would probably want to include it in a public cloud so that everyone can gain access.

But if you're building out a cloud -based application that is for internal use only,

you may want to deploy this to your own virtualized local data center where you have a private cloud.

organizations, we often use both of these.

And we need a hybrid configuration of both public and private clouds for all of these applications.

One type of cloud model is software as a service, or SAS.

This is commonly associated with software that is on demand.

You have a login screen in your browser, you log in, and now you have access to the application.

Someone else has written the application, someone else manages the application, your data is stored somewhere within that application,

and you don't have to do anything else to be able to use that particular app.

You don't have a local installation of software, manage or upgrade any of the software itself.

Instead, you simply log in and use the app.

This allows for centralized management of the application and the data that you're putting into the application,

which means everything is being stored on a third party cloud platform.

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.

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.

There may be times when you would like to build your own application and deploy and manage your own data,

and all you really need are the computing resources to be able to run that application.

In that model, you want to use Infrastructure as a Service, or IAAS.

Sometimes you'll see this referred to as Hardware as a Service,

or HAAS, because you're effectively using hardware in the cloud and then using your own software on top of that.

This means that you would be responsible for installing your software and managing all of the data associated with that software.

If the software needs to be upgraded, you would be the one to upgrade it on your infrastructure as a service model.

The application that you're using and the data that you're putting into that application is still in the cloud.

But you have much more control over the access and security of that data when you're using infrastructure as a service.

A good example of infrastructure as a service is with web service providers, where you can buy time on a particular web server,

and they make that server available to everyone on the internet.

A middle ground between software as a service and infrastructure as a service is Platform as a Service, or PAAS.

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.

The cloud provider gives you all of the tools necessary to build this particular app.

You can think of this as a series of building blocks provided by the Platform as a Service infrastructure,

filled out those blocks to create your own application.

The underlying engine that runs the application is the responsibility of the Platform as a Service provider.

And your responsibility is to build and maintain the apps that are running in Platform as a Service.

A good example of a Platform as a Service infrastructure would be something like Salesforce .com,

where they give you all of the tools necessary to create a customized application running on the Salesforce .com platform.

Here's an example of a cloud responsibility matrix that you might find with any cloud service provider.

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.

Obviously, with on -prem, everything from the data to the applications to the physical data center are all the responsibility of the customer.

But with infrastructure as a service, you have the physical data center, the physical network, physical hosts, all provided by the cloud provider.

And then you handle all of the other pieces of that particular application.

With Platform as a Service, you can see that network controls,

applications, and the identity and directory infrastructure may be shared between the customer and the cloud provider.

But you'd still be responsible for the accounts, devices, and the information and data.

With Software as a Service, much more of these are provided by the provider themselves.

Everything associated with the applications is clearly in the responsibility of the provider.

Everything above that would still be the responsibility of the customer.

So depending on the type of infrastructure you want, and the type of responsibility that you're willing to take on,

you'll need to pick the right cloud model for your application deployment.

Conditional Statements: Phrases such as "If you're creating an application..." help you understand how to express hypothetical scenarios in English, a skill that is invaluable for both speaking and writing.
Use of Passive Voice: The phrase "your data is stored somewhere within that application" demonstrates passive voice utilization, which is common in technical language and can enhance your grammatical variety.
Comparative Structures: Terms like "a middle ground between software as a service and infrastructure as a service" equip learners with the ability to make comparisons, a frequent requirement in both everyday and academic language.

Practicing these structures through repetition and the shadowing app can solidify your understanding and application in conversation.

Common Pronunciation Traps

As you practice speaking along with the video, pay attention to specific words and phrases that may present challenges in pronunciation:

Infrastructure: This term can be tricky due to its syllable structure. Ensuring you stress the correct syllables will improve your clarity.
Application: Given its frequent usage, practicing this word helps for smoother speech, especially when talking about technology.
Hybrid: This word can be easily mispronounced. Focus on breaking it into parts to maintain its correct pronunciation.

What is the Shadowing Technique?

Shadowing is a science-backed language learning technique originally developed for professional interpreter training and popularized by polyglot Dr. Alexander Arguelles. The method is simple but powerful: you listen to native English audio and immediately repeat it out loud — like a shadow following the speaker with just a 1–2 second delay. Unlike passive listening or grammar drills, shadowing forces your brain and mouth muscles to simultaneously process and reproduce real speech patterns. Research shows it significantly improves pronunciation accuracy, intonation, rhythm, connected speech, listening comprehension, and speaking fluency — making it one of the most effective methods for IELTS Speaking preparation and real-world English communication.
