Cloud Computing

 

CLOUD COMPUTING

In Simplest terms, cloud computing means storing and accessing the data and programs on remote servers that are hosted on the internet instead of the computer’s hard drive or local server. Cloud computing is also referred to as Internet-based computing. 

Cloud Computing Architecture: Cloud computing architecture refers to the components and sub-components required for cloud computing. These components typically refer to:

1. Front end(fat client, thin client)
2. Back-end platforms(servers, storage)
3. Cloud-based delivery and a network(Internet, Intranet, Intercloud).

Hosting a cloud: There are three layers in cloud computing. Companies use these layers based on the service they provide.

• Infrastructure
• Platform
• Application

        Benefits of Cloud Computing

• 1. Lower IT infrastructure and computer costs for users
  2. Improved performance
  3. Fewer Maintenance issues
  4. Instant software updates
  5. Improved compatibility between Operating systems
  6. Backup and recovery
  7. Performance and Scalability
  8. Increased storage capacity
  9. Increase data safety
  
  

  Types of Clouds

  There are four different cloud models that you can subscribe according to business needs. Following are the different Types of Clouds:

• 1. Private Cloud: Here, computing resources are deployed for one particular organization. This method is more used for intra-business interactions. Where the computing resources can be governed, owned and operated by the same organization.
  2. Community Cloud: Here, computing resources are provided for a community and organizations.
  3. Public Cloud: This type of cloud is used usually for B2C (Business to Consumer) type interactions. Here the computing resource is owned, governed and operated by government, an academic or business organization.
  4. Hybrid Cloud: This type of cloud can be used for both type of interactions – B2B (Business to Business) or B2C ( Business to Consumer). This deployment method is called hybrid cloud as the computing resources are bound together by different clouds.
