A cloud database is a database that typically runs on a cloud computing platform,

services make the underlying software-stack transparent to the user
A cloud database is a scalable content database running on a cloud computing platform
that could be private, public or hybrid.
There are two cloud database environment models, namely, Traditional cloud model
and Database-as-a-service (DBaaS).
In the Traditional cloud model, the content database will be run on the particular
enterprise’s infrastructure and any oversight will fall into the shoulders of IT staffers of
the company.
On the other hand, DBaaS runs on the service provider’s infrastructure and they (the
vendor) would be responsible for any hitches or glitches should they occur. The service
provider assumes the full responsibility of handling client database leaving them to
focus on operations and business goals.

Here are the main advantages of cloud databases:
Getting rid of physical infrastructure — It is the responsibility of the cloud service
provider to maintain the database, provide storage and other infrastructure.
Scalability — Contracting with DBaaS, allows for automatic scalability most of the time,
during peak business hours or unexpected spikes during festivals and special days.
Cost effectiveness — Reduced capital expenditure for enterprises is another advantage,
because they no longer have to worry about operational costs or upgrading the
infrastructure because all this will be handled by the cloud vendor.
Latest technology availability — Enterprises no longer have to worry about shelling
money on buying new technologies because updated infrastructure is the headache of
the cloud vendor.

Top 10 best cloud storage services of 2017
1. Dropbox
The Granddaddy of cloud storage, Dropbox offers a rather measly 2GB of free storage,
but this can be increased up to 16GB free of charge by linking your Dropbox to social
media and referring friends to join the service.
Dropbox Business subscriptions allow users to collaborate on work as well as giving
each person unlimited space in a personal Dropbox account. There are also enhanced
features for file recovery and versioning. Business pricing starts from $12.50 per user
(around £10, AU$17).
Price: 2GB free. 1TB for $9.99 a month (around £8, AU$13) with Dropbox Pro

2. Google Drive
Google Drive is a natural choice for owners of Android devices as it's already integrated,
but users of other platforms may appreciate the generous free storage too. You can also
store high definition photos on your mobile phone with companion app Google Photos,
and make use of Google's own office suite (now known as G Suite).
Downsides include the fact that the web interface isn't very easy-to-use, although
Windows and Mac users can download a desktop app to drag-and-drop files easily.
Price: 15GB free. 100GB for $1.99 a month (around £1.50, AU$2.50). 1TB for $9.99 a
month (around £8, AU$13).

3. Mega
With an insanely generous free tier and a simple drag-and-drop interface, Mega is one
of the cloud storage heavyweights. There's a handy mobile app to allow you to upload
files and photos, as well as sync clients with desktop machines.
Mega claims that all data stored in its cloud is encrypted on your device before it
reaches the firm’s servers. As the company has released the source code to its sync
client, experts can check that there are no vulnerabilities.
Price: 50GB free. 200GB for €4.99 a month (around £4, $5, AU$7)

4. OneDrive
OneDrive (formerly SkyDrive) is integrated into Windows 10's file explorer. You don't
have to download an additional app – it's there to use out of the box, which is obviously
very convenient for those who have made the jump to Microsoft’s newest operating
system.
Microsoft's Photos app can also use OneDrive to sync pictures across all your devices.
There's an app for Android and iOS devices, and there's even one in the App Store for
Mac users (although it has received mixed reviews).
Price: 5GB free. 50GB for $1.99 a month (around £1.50, AU$2.50)

5. iCloud
If you want to back up your iPhone to iCloud, you'll need more than the free 5GB
allowance Apple gives you, but compared to rivals iCloud prices are very reasonable.
The Mac Finder app integrates iCloud Drive, where you can store any files you wish.
Documents created in the iWork office suite are also saved to iCloud and can sync
across your devices. Windows users can also sync their files with iCloud Drive using the
official client, and access the iWork apps on the iCloud website.
Price: 5GB free. 50GB for $0.99 a month (around £0.80, AU$1.30). 200GB for $2.99
(around £2.50, AU$4)

6. Box
Box's website currently seems to be pushing its business plans as clicking ‘sign up’ takes
you to the biz subscription page where for $15 per user (around £12, AU$20) you can
benefit from advanced collaboration options and unlimited storage.
As Box has been around for a while, it is supported by a number of mainstream apps
such as Google Docs and Office 365. The Box Sync client is available from the Downloads
page for Mac and Windows, plus there's also an official Android client.
Price: 10GB free. 100GB for $10 a month (around £8, AU$13)

7. NextCloud
NextCloud isn’t an online cloud storage provider itself, but offers free software to
download and install a cloud storage service on your own server. Using a server on your
home network for cloud storage is much faster. You can also enable encryption and
make sure the information never leaves your home network, which is far safer.
If you've no server or IT experience, you can even purchase a preconfigured NextCloud
Box from the website which comes with a 1TB hard drive and will work with an
inexpensive Raspberry Pi board to keep your data synced.
Price: Free to install and use. Self-hosting so storage costs vary. NextCloud Box is $79.99
(around £65, AU$105)

8. SpiderOak
SpiderOak is part of a new trend of zero knowledge cloud storage providers. The
website claims that after installing the client your data is encrypted before syncing.
Unfortunately since SpiderOak hasn’t made the client source code public, there's no
way to confirm this.
The SpiderOakOne client is available for Windows, Mac and Linux as well as Android and
iOS. You can also log in via the web interface but privacy lovers may prefer not to as it
exposes your password to SpiderOak employees.
Price: 2GB free. 250GB for $9 a month (around £7, AU$12). 1TB for $12 a month
(around £10, AU$16)

9. IDrive
IDrive offers continuous syncing of your files, even those on network drives. The web
interface supports sharing files by email, Facebook and Twitter. Cautious or click-happy
users will be pleased to hear that files deleted from your computer are not
automatically deleted from the server, so there's less danger of removing something
important accidentally.
IDrive also offers IDrive Express – a service whereby if you lose all your data they will
ship a physical hard drive out to you, allowing for the swift restoration of all your backed
up files.
Price: 5GB free. 1TB for $52 a year (around £40, AU$70)

can upload, so feel free to sync large media files with pCloud.
The service is available for all desktop and mobile platforms – users can also log in via
the website. The company itself is registered in Switzerland which has strong privacy
laws, and you can also pay a premium of $3.99 (around £3, AU$5) for pCloud Crypto to
lock (and unlock) individual files with passwords.
Price: 20GB free. 500GB for $4.99 a month (around £4, AU$6.50). 2TB for $9.99 a month

iCloud Drive
If you use a Mac or iOS device, then iCloud Drive is at your fingertips. It is part of the OS
X Finder, and an iOS app gives you quick access to files you've stored there on your
iPhone or iPad.
You can even install iCloud on Windows, which offers similar integration with the
Windows Explorer (as well as syncing of data, such as contacts, calendars, bookmarks,
and more). And if you're using a public computer, you can access your files via a web
browser at icloud.com.
If you own a Mac or iOS device, you get a free 5 GB on iCloud Drive. If you need more
storage, you can purchase it for the following cost (US prices):

OneDrive
Microsoft OneDrive is an adjunct to the company's Office 365 productivity suite,
available on subscription. Offering a service similar to that of Dropbox and Google Drive,
OneDrive lets you store and access files and photos on Mac, Windows, iOS, Windows
Phone, and Android. If you have a Windows PC, then OneDrive is already installed. If you
have a Mac, you can download an app from the Mac App Store; unfortunately, this app
has a slew of bad reviews at the time of this writing.
OneDrive offers 5 GB free, and 50 GB for $1.99 per month:

Dropbox
Dropbox is one of the easiest to use cloud storage providers. Unlike iCloud, it only stores
files; it doesn't sync data (though some apps do sync data to Dropbox). Dropbox is
available for just about every platform, be it iOS, Android, Windows Phone, Mac,
Windows, and even Linux.
On a computer, Dropbox creates a folder and keeps it in sync with all your devices. It's
one of the simplest services to use, and also offers advanced features such as shared
folders, and the ability to copy a Dropbox link to allow someone to download a file
you've stored in your folder. Many desktop and mobile apps feature tight integration
with Dropbox, and you can access files from the Dropbox website, making it one of the
best choices for cloud file storage.

A free Dropbox account gives you 2 GB, and you can purchase more storage: You can get
a Dropbox Pro plan, offering 1 TB, for $9.99 a month. Unfortunately, there's nothing in-
between the paltry 2 GB and the comfortable 1 TB. There is also a Business plan, with
unlimited storage, for companies with large teams sharing files.

Google Drive
Google Drive is a lot like Dropbox. It creates a folder on your computer, where you can
store files, and apps on mobile devices let you access the contents of this folder.
Individual Google apps, such as Docs, Sheets, and Slides, store there files on Google
Drive as well. You can use Google Drive on Mac and Windows, and on Android or iOS
devices. You can also use Google Drive with a Chromebook, or through a web browser.
With 15 GB free, Google lets you feel comfortable right away. Note that this storage
applies to files, your Gmail account, and Google Photos (if you use those services), but
not Google Docs. You can create and store as many as you want, and if you need more
storage, Google lets you go large. Here's how much it costs:
