Which companies are major players in the cloud services market?
-Major players in the cloud services market include Amazon Web Services (AWS), Microsoft Azure, IBM, Google, and Alibaba.
How do smaller companies benefit from cloud computing?
-Smaller companies benefit by not having to invest in expensive hardware for data backup, and they can store and access unlimited data online, often on a subscription basis.
What is the subscription pricing model for cloud services?
-The subscription pricing model allows customers to pay a monthly fee for cloud services and scale their usage up or down as needed, providing flexibility.
What are some risks associated with storing data in the cloud?
-Risks include data loss during internet outages, the threat of cyber attacks, and the difficulty of switching between different cloud providers due to compatibility issues.
Why might large cloud companies have significant power over user data?
-Large cloud companies may have significant power over user data because of the difficulty users face in syncing accounts across different cloud platforms, leading to a reliance on a single provider.

đ€ïž Understanding Cloud Computing
The paragraph introduces the concept of cloud computing, explaining it as a global network of servers that function as a massive hard drive. It clarifies that while data is not stored in the sky, the term 'cloud' is used metaphorically to describe the remote servers that store and manage data. Examples of cloud services include Gmail, Netflix, and Dropbox. The paragraph also contrasts the traditional method of data backup on physical devices like CD-ROMs or hard drives with the modern approach of cloud backup, which allows for data access from anywhere with an internet connection. The benefits for consumers include peace of mind, accessibility, and reduced need for local storage, potentially lowering device costs. Businesses also benefit from cloud computing, with a significant increase in revenue from cloud services. Major players in the market include Amazon Web Services (AWS), Microsoft Azure, IBM, Google, and Alibaba. The paragraph concludes by discussing the subscription-based pricing model of cloud services and the substantial revenue generated by AWS for Amazon.

Transcripts
Have you ever taken a minute to gaze up at the clouds?
You might see a dog, a dinosaur,
or your data?
Okay, your data isnât actually stored in a cloud in the sky,
but itâs easy to think so when thereâs so much talk about cloud computing.
So how does the cloud work?
The cloud is a global network of servers around the world acting as one massive hard drive.
Every time you sign into your Gmail account, watch a show on Netflix
or open a file from Dropbox, youâre using the cloud.
Before the cloud, you might have backed up your documents, photos or music
to an external device like a CD-ROM or to your computerâs hard drive.
Now, you can back-up all of that information to the cloud.
When I back-up my iPhone to the cloud, my files are sent to servers in Appleâs data centers all around the world.
I can access those servers by connecting to the internet.
So even if I lose or break my phone, not that itâs ever happened before, that data isn't lost forever.
There are a few obvious benefits to consumers from the cloud
besides giving you peace of mind if you lose your phone.
You can access your data anytime, anywhere if youâre connected to the internet.
And you donât have to worry about using up all of the storage on your hard drive.
Meaning you might not have to pay as much for a device that comes with a ton of storage.
Businesses are also benefiting big time from cloud computing.
Itâs estimated worldwide revenue from the cloud will exceed $200 billion in 2019,
that's up from $145 billion just two years ago.
Youâve probably heard of the two biggest names in the market,
Amazon Web Services, known as AWS, and Microsoft Azure.
IBM, Google and Alibaba are also big players when it comes to providing cloud services.
Itâs not just big tech moving business into the cloud.
Smaller companies are buying in too as a way to grow their businesses.
Just think, instead of having to buy all of this hardware to backup your data,
you can store an unlimited amount of information online.
Many cloud services are based on a subscription pricing model.
That means customers pay, for example, a monthly fee for cloud services
and they can scale up or down as needed. And cloud providers are cashing in.
AWS accounts for roughly 12 percent of Amazonâs quarterly sales,
but it generates more than half of the companyâs operating income.
Before we get too excited about the cloud, letâs take a step back and look at some of the risks.
One obvious concern, if all of our data is online, what happens when the internet goes down?
Thatâs what happened in 2013 when an AWS outage took down Instagram, Vine and Airbnb.
Cyber attacks are another big risk with research showing
around one-fifth of all files in the cloud contain sensitive data.
Finally, it can be tough for consumers and businesses to switch between different cloud companies.
I might have a hard time syncing my iCloud and Google Drive accounts.
That can give some big companies, that are already making big money on the cloud,
a lot of power over our data.
