What is Cloud Computing?

 

Cloud storage is a cloud computing model in which data is stored on remote servers accessed from the internet, or “cloud.” It is maintained, operated and managed by a cloud storage service provider on a storage server that is built on virtualization techniques.

Benefits of Cloud Storage:
1. Flexibility

Cloud-based services are ideal for businesses with growing or fluctuating bandwidth demands. If you want to increase, its easy to scale up your cloud capacity. Likewise, if you need to decrease again, the flexibility will be baked into the service.

2. Disaster recovery

Businesses of all sizes should be investing in robust disaster recovery, but for smaller businesses that lack the required cash and expertise, this is often more an ideal than the reality. Cloud is now helping more organizations buck that trend.

3. Automatic software updates

The beauty of cloud computing is that the servers are off-premise, out of sight and out of your hair. Suppliers take care of them for you and roll out regular software updates.

4. Work from anywhere

By using cloud computing, if you have got an internet connection you can work from anywhere. And with most serious cloud services offering mobile apps, youre not restricted to which device youve got to hand.

  • Cloud Computing is a general term used to describe a new class of network-based computing that takes place over the Internet.
  • Cloud computing is a synonym for distributed computing over a network and means the ability to run a program on many connected computers at the same time.
  • These platforms hide the complexity and details of the underlying infrastructure from users and applications by providing very
  • Simple graphical interface or Applications.
  • Cloud Computing is the result of evolution and adoption of existing
  • Technologies and paradigms.

 

TYPES OF CLOUD COMPUTING-

  1. Public Cloud Accessed by any subscriber with an internet connection and access to the cloud space.
  2. Private Cloud – A private cloud is established for a specific group or organization.?
  3. Community Cloud – Shared among two or more organizations that have similar cloud requirements.
  4. Hybrid Cloud – A hybrid cloud is essentially a combination of at least two clouds.

CHOOSING A CLOUD PROVIDER-?

  1. Software as a Service –A SaaS provider gives subscribers access to both resources and applications. Examples of SaaS include Google Apps, Casengo, TradeCard, Salesforce etc.
  2. Platform as a Service -A PaaS provider gives subscribers access to the components. Examples of PaaS include Cloud Foundry, Force.com, Engine Yard, Mendix, and Google App Engine etc.
  3. Infrastructure as a Service?It deals with primarily with computational infrastructure. Examples of IaaS include Google Compute Engine, HP Cloud, and ReadySpace etc.

 

 

ADVANTAGES OF CLOUD COMPUTING:?

  • Lower computer costs:

You do not need a high-powered and high-priced computer to run cloud computing’s web-based applications.

  • Improved performance:

With few large programs hogging your computer’s memory, you will see better performance from your PC.

  • Reduced software costs:

Instead of purchasing expensive software applications, you can get most of what you need most cloud computing applications today, such as the Google Docs suite.

DISADVANTAGES:

  • Requires a constant Internet connection
  • Does not work well with low-speed connections
  • Stored data might not be secure
  • Stored data can be lost
