Cloud Computing

What is Cloud Computing?

Cloud Computing is the concept of using computer networks including personal computers and mobile devices, to facilitate retrieving and storing information from anywhere at any time.

There so many uses of Cloud Computing. Some of them are listed below.
  • Create new apps and services
  • Store, back up and recover data
  • Host websites and blogs
  • Stream audio and video
  • Deliver software on demand
  • Analyse data for patterns and make predictions

Let's talk about three main types of Cloud Computing.

  1. IaaS   -  Infrastructure as a Service
  2. Paas   -  Platform as a Service
  3. SaaS  -  Software as a Service

Infrastructure as a Service [ IaaS ]

This provides a virtual environment of Servers to provide space to store data and software applications with the help of server computers and also to provide various resources through the use of large data centers established.

Eg :- Obtain the facilities of Server Space and Firewall through Cloud Computing even though you do not own them.

Platform as a Service [ Paas ]

This Platform provides necessary server environment for Software development. This gives facilities including Operating System, Programming Language Environment, Database and Web Server.

Eg :- Software can be developed in the cloud computer service even though you do not have installed operating system or compilers in your computer.

Software as a Service [ SaaS ]

This means that it provides the ability to use software installed in Cloud without installing them Software in the PC of the user. This helps us to reduce the cost and complexity of buying and managing hardware and secondary, developing software required for the main software for the user to use it.

Eg :- In Android Devices, Word Processing Software, Spreadsheet Packages & etc, can be used using only the web browser; without installing those packages in the device.

Advantages & Disadvantages of Cloud Computing


  • Lower Software Cost
  • Processing Speed is High
  • Improved Performance
  • Fewer Maintenance Issue
  • Instant Software Updates
  • Ability to Scale Elastically
  • Makes Data Backup & Disaster Recovery


  • Requires Constant Internet Connections
  • Doesn't Work Well in Low Speed Internet Connections
  • Chances for Hackers to Steal login Information and to Collect your Data in the Cloud.

Types of Cloud Deployments

  1. Public Cloud
  2. Private Cloud
  3. Hybrid Cloud

Public Cloud

Public Clouds are owned and operated by a Third-Party Cloud Service Provider. They deliver their Computing Resources like Servers and Storage over the Internet.

Microsoft Azure, Amazon Elastic Compute Cloud [EC2], Google AppEngine are some examples for Public Cloud.

Private Cloud

A Private Cloud is a Cloud Computing Resource used by a Single Person or a Business/ Organisation.

Hybrid Cloud

Hybrid Clod means a combination of Public Cloud and Private Cloud. This combination allows to share data and information between them.


  1. Thanks for sharing. Personally, i am not electronic savvy. However, you site provided thorough information.

  2. I never understood the cloud:) This brings down to level I can surely understand

  3. I didn't know anything about cloud computing thank you for teaching me something new.

  4. I find cloud computing to be such a great thing I love being able to start something in one place and carry it on in another.

  5. I have no idea about cloud computing of how it worked. You explained it really well and simple. Glad that you shared your knowledge. I'm not that computer savy.


  6. I always get confused with all the options put there, so this post is a great way to understand the different options. Thank you so much for sharing this!

  7. Great post. This is such a confusing topic for people like myself!

  8. I really depend on Cloud Storage for alot of my computer needs. So this information is definitely very helpful to me.

  9. I currently am using cloud computing and it is awesome. I highly recommend it.

  10. This is so important to know, when you have a lot of data to store or back up!

  11. Cloud computing is the wave of the future for sure, allowing to access your data in as many places as possible without having to store it everywhere. Good information.

  12. What I love about cloud computing, especially cloud storage is the fact that it can easily be accessed from just any computer or phone anywhere.

  13. I am so old school and keep resisting the cloud. It requires me to always have a good internet connection, which I sometimes don't have. One day I will join this century and join the cloud!

  14. I seriously love cloud storage. It's saved me so many times when ive needed to access my information on one device or another.

  15. I never understood the cloud, you made it more clear. thanks. Great concept should have started to use it years ago. I have lost data so many times due to devices, and it all could have been on the cloud.

  16. This post has made the cloud more understandable for me. I need to use my cloud storage more

  17. This is some very technical information. I am pretty techie but this is definitely above my pay grade. Lol
