Cloud computing is Internet-based software that ensures the delivery of services, databases, storage, software, networking and much more over the internet (the cloud). The companies who provide these services are called cloud providers. They charge for those services in the same way as we pay utility bills at home.
Cloud computing uses many network servers to provide services to the large enterprises and end users. Network servers map IT systems with large pools of data that are connected together. Frequently, virtualization techniques are used to enhance the power of cloud computing.
Nowadays, many companies have their own cloud computing technologies. For instance, IBM offers “Blue Cloud” technology that is based on open standards and open source software. Also, it connects computers together to deliver web 2.0 capabilities like mobile commerce.
As a result, most people today are using cloud computing technologies and they don’t realize it. For instance, we use internet to watch movies, TV, streaming on YouTube, play games, store pictures, send emails and edit documents. Most noteworthy, the global organizations, Non-government Organizations (NGOs) and government agencies are using this technology for several reasons (given below):
- Creating new services and apps
- Storing, recovering, and backup data over the internet
- Hosting blogs and websites
- Streaming video and audio
- Delivering software on demand
- Analyzing data and services to make predictions.
Benefits of Cloud Computing
It produces a complete turnaround in the traditional arena of Information Technology.
Cloud computing is cost-effective. Therefore, it eliminates the capital expense of purchasing software and hardware, ample electricity for power and cooling of expensive server machines and IT experts for the management of infrastructure.
The speed of cloud computing services is very fast. Even large amounts of computing resources are provisioned in minutes with a few mouse clicks.
Global Scale: It includes the ability to scale elastically. In the sense of cloud computing, Global scale means providing the right amount of Information Technology resources. For instance, it provides computing power, bandwidth, storage and speed.
Productivity: Large datacenters require a good deal of racking and stacking hardware set up, software installations and many other IT related tasks that consume a lot of money and time. Also, cloud Computing enables us to remove all these difficult tasks. Therefore, we can spend our precious time on planning more important business goals.
Performance: The cloud computing services run on worldwide networks, connected through Wide Area Networks (WAN). These are regularly upgraded to the modern generation of fast, reliable and efficient hardware.
Reliability: A sudden electricity failure may cause damage to your computing hardware. Therefore, it prevents data loss by means of backup and disaster recovery. As a result, there are many websites over the internet that enables us to store important data online such as Dropbox and Google drives.
Therefore, it has been realized that there is a huge demand for cloud computing nowadays. In conclusion, from a global corporations to end user, everybody is capitalizing on cloud computing’s helpful services rendered by cloud providers.
