Cloud Computing – Rapid Growth in IT industry

Cloud Computing 

Cloud computing is the latest technology that delivers IT services via Internet on the basis of pay for use. This technology enables the cloud customers to access IT resources easily and pay only for the services used by them. The customers store and access the data and programs over the Internet rather than storing them on a local server or computer.  

The cloud computing has certain models and services that makes the cloud computing successful and accessible to the users.  

Cloud Computing Models: 

Cloud computing model refers to the type of the access to the cloud. These are of four types –  

  • Private Cloud  
  • Public Cloud  
  • Hybrid Cloud  
  • Community Cloud  

Private Cloud: 

Private Cloud model is accessible within a particular organisationThe operation and management of this model is taken care by the organisation itself. This model is secured due to its privacy.  

Public Cloud: 

Public Cloud infrastructure is used in business to customers applications. In this model the computing resources are owned by an organisation or government known as service provider. The service provider provides computing services openly to the customers.  

Email and social networking sites can be the example of public cloud system.  

Hybrid Cloud: 

Hybrid Cloud model is the combination of Private and Public cloud. In this system the private cloud is used for internal activities and public cloud is used for outside activities.  

Community Cloud: 

This model is used by a group of organisations with a shared network connection.  

Cloud Computing Services: 

Cloud computing service is refers to the type of service the cloud provides. Could computing services are three types –  

  • Infrastructure as a Service (IaaS)  
  • Platform as a Service (PaaS )  
  • Software as a Service (SaaS) 


Infrastructure as a Service (IaaS): 

Infrastructure as a Service is the basic cloud service provided by the cloud computing companies. It provides a virtual server platform to access virtual machines or virtual resources. It allows the user to controlmanage and create the infrastructure resources at the cloud.  

Platform as a Service (PaaS): 

Platform as a service provides a platform and environment to the users for developing their own applications and software. This service is delivered to the users via Internet. This service is beneficial for software developers, web developers and businesses. It’s platform covers software support, storage, networking, testing, hosting and maintaining applications.  

Software as a Service (SaaS): 

Software as a Service or SaaS provides a software to the users over the internet. User can subscribe to the software monthly basis via internet. This service can be accessed from anywhere in world as a subscriber via internet.  

Advantages of Cloud Computing: 

Low Cost: There is no requirement of high power computers as the applications run on cloud.  

Storage Capacity: Cloud has the unlimited storage capabilityThere is no need of extra storage devices.  

All Time Availability: Cloud Computing Services are available for every time as all issues are solved remotely through technical support.  

Increases the computing power: Cloud servers are highly capable of running applications and processing various tasks.  

Security: Cloud Computing is a highly secured system as the data is stored over the internet. There is no loss of data 

Reduced Software Cost: As there is no need to purchase the software, the software cost is reduced.  

Disadvantages of Cloud Computing: 

Internet SpeedCloud services require high internet connection.  

DowntimeIf the cloud company’s servers are not accurate, it may lead to downtime. During downtime data access may decline.  

Top Cloud Computing Companies are: 

  • Amazon Web Services  
  • IBM Cloud  
  • VMware  
  • Salesforce  
  • Adobe  
  • Microsoft Azure  
  • SAP 
  • Dropbox
  • Oracle  
  • Google Cloud services  
  • Octal IT solutions  
  • Cloud helix 
  • Sunflower Lab 
  • Netflix  
  • Instagram  
  • Apple


Cloud computing is very useful and has a bright future as companies are generating a lot of data, which has to be stored for future. Could Computing helps the users to grow their business by providing the best cloud services.
