Introduction to the Cloud Computing
What is cloud computing?
The word cloud computing is mixture of two words “cloud” & “Computing”. Word cloud means “over the internet” & In computing many services comes under the computing like Servers, Storage, Databases, Networking, Software, Analytics etc.
so in simple we are saying cloud computing is delivery of services over the internet.
Benefits of Cloud Computing
In cloud computing we are easily scale up or down resources on demand.
It minimize the expenses of buying hardware, software, setting up, running up data centers on rack servers & You have to pay only for those services you use.
In the on site set up computing services take too much time to setup a network & hardware, datacenters require racking & stacking it takes a lot of time , software patching and many more efforts that will effects productivity. So in cloud computing it will removes that waste of time and increase the productivity.
The services of cloud computing will be runs on world wide network of secure datacenters, which was regularly upgraded time to time when new changes are come and provide latest fast & new generation efficient hardware.
This will maintains and increase the performance.
In cloud computing it will proper takes backup of your data, this will saves data in case of any disaster and recover it.
Uses of Cloud Computing
- Easily create new apps
- Take proper backup of data
- Give hosting to websites
- Analyze data
- Deliver software & hardware of demand.
Types of Deployments
- Public Cloud
- Private Cloud
- Hybrid Cloud
Public cloud is the third party cloud, It will owned and operated by companies, the companies are also known as cloud service provider and it will provide you services like hardware, software, supporting infrastructure as per requirements, we don’t need to purchase any things all the services are managed by cloud service provider.
Leading Cloud service provider :
- Amazon Web Service (AWS)
- Microsoft Azure
- Google cloud Platform
Private cloud is the cloud platform owned by the single organization, It will physically located on the datacenter of the company.
The services & infrastructure are manged on the private network.
Hybrid cloud is the combination of the public & private cloud. It gives great flexibility & more better deployment option.
Type of Services
Infrastructure as a Service (IaaS)
It is the the type of cloud where you rent IT infrastructure like Servers, Virtual Machines, storage, Network etc from cloud service provider. It will work on the basis of pay-as-you-go .
Platform as a Service (PaaS)
It supplies on demand requirement for developing, testing, delivering and managing software applications, It designed to ease the worry of managing & setting up the infrastructure needed for development.
Software as a Service (SaaS)
It delivers the software application over the internet, on demand & typically on the subscription basis.
