Latest News 6th Aug 2020: Bharti Airtel partners with Amazon to grow cloud business
Whenever a person, either thinking of starting a business or expanding a business which has a good involvement of technology in it, a situation comes when a question arises that what amount is to be invested, how much space will be required for installing the whole setup, etc.
There is always a thought that what if something in that physical setup goes wrong, what will be its service cost, do I need to pay even when I am not using it and a series of complex questions..!!
Then comes a technology that packs everything related to software, infrastructure, and platform virtually and now you just need to pay as per your requirement and usage.
Cloud computing is the delivery of on-demand computing services — from applications to storage and processing power — typically over the internet and on a pay-as-you-go basis.
In simple words, it is a ‘Mall’ of computer services that is virtual and you have different vendors for different kinds of services you need and you pay them as per your use.
Benefits of using Cloud Computing
Since, a service which use to run in the traditional manner has transformed to a virtual model, hence it brings a lot of benefits for the user.
Which services are incorporated under the ‘Cloud’?
There are three types of services that cloud computing offers:
- Infrastructure as a Service(IaaS)
- Platform as a Service(Paas)
- Software as a Service(SaaS)
Infrastructure as a Service
Infrastructure-as-a-Service (IaaS) refers to the fundamental building blocks of computing that can be rented: physical or virtual servers, storage, and networking. This is attractive to companies that want to build applications from the very ground up and want to control nearly all the elements themselves, but it does require firms to have the technical skills to be able to orchestrate services at that level.
Platform as a Service
Platform-as-a-Service (PaaS) is the next layer up — as well as the underlying storage, networking, and virtual servers this will also include the tools and software that developers need to build applications on top of that could include middleware, database management, operating systems, and development tools.
Software as a Service
Software-as-a-Service (SaaS) is the delivery of applications-as-a-service, probably the version of cloud computing that most people are used to on a day-to-day basis. The underlying hardware and operating system are irrelevant to the end-user, who will access the service via a web browser or app; it is often bought on a per-seat or per-user basis.
