Have you ever heard about Microsoft Azure, Google Cloud, VMWare? So let’s get to know about cloud computing which is one of the demanding topics in the IT world right now.

What is Cloud Computing?

Cloud computing is the delivery of computing services on demand. The computing services include servers, networking facilities, databases, storage facilities, software, analytics etc. and they are provided to the requested users via the Internet, ‘The Cloud’. In other words it is a network of remote servers hosted on internet which does processing, sorting, managing and storing of data other than in a personal computer or a local server.

Cloud computing leads to faster innovations, make resources flexible and to economies of scale. Among the prominent users of cloud computing, governments, top most enterprises in the world, many renowned companies in the IT industry can be seen.

Mostly cloud customers can, pay-as-you-go, on per use basis. So, the users pay for what they used and the rest of the resources are available for others. This leads to minimize the wastage of resources and get the maximum benefit from them.

Types of Cloud Computing

The same type of cloud computing might not be the ideal solution wanted by all of the cloud users. Therefore to provide optimal service to the cloud users there are several types and models of clouds available. The three main ways to deploy cloud services is public, private and hybrid cloud.

Public clouds-Public Clouds are owned and operated by third party cloud service providers. They deliver their computing services over the internet. The hardware, software and other infrastructure in the private cloud are owned and managed by the cloud service providers. Examples are Microsoft Azure, Oracle, Amazon Web Services (AWS) etc.

Private clouds– Cloud computing resources which are used by a specific business or an organization. Sometimes a private cloud can be located in a private data center of the company or hosted by a third party cloud service provider.

Hybrid clouds – A combination of public and private cloud. Data and applications can be shared between the clouds. So this provides greater flexibility.

Types of cloud Services

There are four main categories of cloud computing. They are,

Infrastructure as a Service (Iaas) – The most popular way of cloud computing. The users rent the cloud services and infrastructure such as servers, storage, networking, virtual machines, software etc. from a third party cloud service provider on pay-as-you-go basis. Some Cloud Service providers are Google Cloud, Microsoft Azure, oracle, VMWare, Amazon Web Services (AWS), IBM Cloud, SAP etc.

Platform as a Service (PaaS) – Mainly designed to support developers for mobile application testing, application testing etc. It is an on-demand development platform for application developers.

Serverless Computing – Providing of back-end services by a cloud service provider on as – used basis.

Software as a Service (SaaS) – Delivering of software applications over the internet on demand.

Benefits of Cloud Computing

-Eliminates the capital cost of buying hardware, software and the maintenance cost of them.

-Global scale therefore can be obtained from anywhere despite your physical location.

-Higher productivity

-Higher speed

-Higher performance

-Highly reliable

-Higher security

-Can store, backup and recover data

Cloud computing is a greater leap in the Information Communication Technology which makes computing services and resources accessible by and available for everyone. So let’s wait and see how cloud computing changes the world…..
