It is the latest technology that has made a huge change in the way data is stored and processed in servers. Cloud computing delivers the current on-demand computing services all over the internet after payment is done. Cloud services are used on a daily basis without even realising it.
Mobile applications, social media websites, email services, online shopping websites like Amazon, Jabong etc are all cloud-based. Cloud computing is extremely beneficial for companies since it helps to deliver services to the companies like Hardware, software, storage, etc. without having to build in-house computing infrastructure.
There are three types of cloud computing-
- Infrastructure as a service (IaaS)
- Software as a service (SaaS)
- Platform as a service (PaaS)
WORKING OF CLOUD COMPUTING
Cloud computing has revolutionised the way data is saved and accessed to. The companies no longer need to purchase computing infrastructures or data centres of their own. They can easily rent everything from applications to storage by cloud service provider. This enables the company to pay only for the services they use and whenever they use it. It helps the companies in saving a lot of money that goes in owning software and maintaining the IT infrastructure. Cloud computing service providers benefit by gaining access to a large customer base.
Cloud computing also allows the developing projects to get completed before time on a low budget. It also lowers the cost of development and testing. Whether it is robotics, artificial intelligence, machine learning, bitcoin, blockchain etc., all the technologies employ the use of cloud computing.
USES OF CLOUD COMPUTING
Cloud computing does a lot of work whether or not one realises it. Cloud computing might only be a decade old but various companies use it. Some of the uses of cloud computing are-
- Creation of new applications and services
- Hosting new websites and web blogs
- Streaming the audio and visual content
- Storing, backing up and recovering from data
- Delivering the software required as per demand
- Analysing the data for any patterns and make new predictions
ADVANTAGES OF CLOUD COMPUTING
Companies can easily increase the computing as per the needs and scale it down when the market is low. There is no more need for investing in the local infrastructure. It provides elasticity to the companies for expansion of the business.
- Workload management
Cloud computing allows important workload for the users to keep running across multiple global regions. It allows online storage which eliminates the need for carrying more equipment for work.
- Flexibility in travelling
The workload of various companies has moved online to or from the cloud which helps in saving a lot of money. New services can be utilised and money is saved.
- Paying for the amount one uses
Cloud computing is based on pay per use. The users can pay on the basis of the number of services used, time of usage and period of usage. Cloud resources get calculated on a granular level. This saves any additional money required to set up the infrastructure. There is no more need for capital investment in purchasing hardware software in order to run the business.
- Self-service provisioning
Be it any kind of workload, the users can spin up resources on demand. The IT administrators no longer need to provide for the compute resources. Cloud computing manages it all. Since it is self-service on demand, it helps in providing services within minutes- saving time and money. There is a lot more flexibility experienced and less pressure in planning.
One can easily deploy the application on a global level within minutes. It helps in giving a better user experience at minimum cost. The onsite datacentres require stacking and racking of hardware, software, managing IT chores etc. Cloud computing eliminates the need for such chores which enable the IT teams to work on increasing productivity.
Since cloud computing helps in backing up data online, there are more chances of security and reliability. Disaster recovery is there. Business continues to work since data can be backed up at multiple sites.
CLOUD COMPUTING EXPECTATIONS
- By the year 2020, as per Forrester, cloud computing market is expected to reach $236 billion which includes services, applications and business administrations.
- In 2016 to 2026, cloud storage expenses are expected to increase at 16%.
- By 2018, more than 50% of IT would employ the use of cloud computing (as per IDC). Cloud computing is soon going to take over all the mediums of delivering information.
Currently, cloud storage is an essential part of business exercises. Various companies have realised the reason for moving the storage to the cloud. There are various benefits of the computing in business and to end users.
