Cloud Computing : Pros and Cons

What is Cloud Computing

Cloud computing” refers to computer tasks which are performed using services delivered entirely over Internet. It is an evolution constituting a movement away from applications needing to be installed on an individual’s computer towards the applications being hosted online. In the past software had to be shipped to the costumer via CD-ROM and after that updates were downloaded in order to protect the software and keep it bug free but now its all lies in the heart of internet referred as

Types of Cloud Computing

Various vendors in the market place offer costumers with basically many types of services such as IBM. One of the types is SAAS( Software as a service) and the second one is PaaS( Platform as a service) and the third one is IaaS (Infrastructure as a service). Digging into the details of the above mentioned types SaaS is a cloud based software or application service that is operated on the distant computers owned by the huge companies such as IBM that connect to users through internet and usually by web browsers. Having said that it has huge benefits which are as following

  • Applications and data are accessible from any computer connected to the cloud.
  • If there is a hardware failure or natural disaster there is no risk of losing data.
  • This service can be customized dynamically according to the needs of the costumers

Platform as a service provides a cloud based environment with everything required to complete the life cycle of building and delivering web based applications reducing the cost of hardware and software which in turn helps the consumers to develop applications and access the market faster capturing the value effectively.  In most of the plate form as a service huge business need a middle ware which causes a lot of complexity among the consumers. PaaS reduces the complexity and provides with ease and access.

Infrastructure as a service equips companies with computing resources including servers, networking, storage and data center space on pay per use basis. This has huge benefits including the minimization of the cost as there remains no need in investing hardware. Moreover flexible and innovative services are available on demand to the consumers.

There are three more types of cloud offered to the costumers i.e public cloud, private cloud, hybrid cloud. Public clouds are owned and operated by companies that offer rapid access over a public network to affordable computing resources. With public cloud services, users don’t need to purchase hardware, software or supporting infrastructure, which is owned and managed by providers. A private cloud is infrastructure operated solely for a single organization, whether managed internally or by a third party, and hosted either internally or externally. A hybrid cloud utilizes a private cloud foundation amalgamated with the strategic integration and use of public cloud services. Public and private cloud combine o form a Hybrid cloud because the reality is a private cloud can’t exist in isolation from the rest of a company’s IT resources and the public cloud.

  • Storage:Day by day huge amount of data is being generated creating a space for such an option that can store data. When huge of data is stored costs incur such as hardware cost, expertise cost and many other costs but cloud computing  provides unlimited storage with out the need of huge infrastructure and vulnerable storage hardware.
  • Reduced Costs:  It is for sure that hardware and tangible assets creates ample amount of costs that are reduced by the use of cloud computing proving it to be cost effective and reliable.
  • Mobility: It enables a consumer to access and update the data whether it’s  development platform, suite of office tools or custom content management system – cloud mobility enables access anywhere with a Web connection.
  • Business Security: With the shift to cloud computing there is minimal risk of losing the data either it is the records of costumers or business operations.
  • Access to Automatic Updates : Keeping up to date in the era of technology is as potent as the survival of any business. Cloud computing feeds with automatic updates that reduces a hectic job to buy new updates manually.
  • Back up and Disaster Recovery becomes more automated, timeless, readily available.


There are limited cons of cloud computing that originates from the pros if they are not managed properly. Few are listed below

  • Control: Huge amount of data brings a task of managing and controlling it with great care so that consumer privacy does not get invaded. Moreover the ability to outsource the IT burden to a specialized vendor but with a move to the cloud you do give up the in-house control of a traditional IT department.
  • Compatibility can be another con in a way making sure every existing tool, software and computer is compatible with the Web based service, platform or infrastructure.
  • Contracts or Lock downs 
  • Security 


As the data is growing exponentially and more awareness is growing among costumers there is an absolute need of shift towards Cloud Computing which has numerous benefits than its harms. If managed properly these harms are totally eliminated leaving the consumers more satisfied ans up to date in terms of their growing needs.
