What is Cloud :
The term refer to a network or the internet.
What is Cloud Computing : Cloud Computing is a technology that uses remote servers on the internet to store, manage, and access data online rather than local drives. the data can be anything such as files, Images , Documents, audio, Video or more...
There are the following operations that we can do using cloud computing
- Hosting blogs and website.
- Storage, back up and recovery of data
- Streaming Video and audio
- Developing new application and services.
- Delivery of software on demand.
Why we should use Cloud Computing ?
Small as well as large IT Companies, follow the traditional methods to provide the IT infrastructure. that means for any IT company, we need a server room that is the basic need of IT Companies.
To manage the server ,That needs a mail server, networking, firewalls, routers, switches, QPS, high net speed and a maintenance engineer , so to establish such IT Infrastructure, we need to spend lots of money. to overcome all these problem and to reduce the IT Infra cost, cloud computing came into picture.
Characteristics of Cloud Computing1)Agility
The cloud works in a distributed computing environment. It shares resources among users and works very fast
2)High Availability and reliability
The availability of servers is high and more reliable because the chances of infrastructure failure are minimum.
3)High Scalability
Cloud offers "on-demand" provisioning of resources on a large scale, without having engineers for peak loads.
4)Multi Sharing
With the help of cloud computing, multiple users and applications can work more efficiently with cost reductions by sharing common infrastructure
5) Device and Location Independence
Cloud computing enables the users to access systems using a web browser regardless of their location or what device they use e.g. PC, mobile phone, etc. As infrastructure is off-site (typically provided by a third-party) and accessed via the Internet, users can connect from anywhere
6)Maintenance
Maintenance of cloud computing applications is easier, since they do not need to be installed on each user's computer and can be accessed from different places. So, it reduces the cost also
7) Low Cost
By using cloud computing, the cost will be reduced because to take the services of cloud computing, IT company need not to set its own infrastructure and pay-as-per usage of resources.
8) Services in the pay per use mode.
Application Programming Interfaces (APIs) are provided to the users so that they can access services on the cloud by using these APIs and pay the charges as per the usage of services.
