Cloud Computing Tutorial
Cloud Computing tutorial provides basic and advanced concepts of Cloud Computing. Our Cloud Computing tutorial is designed for beginners and professionals.
Cloud Computing Tutorial with high end solution of IT infrastructure. Cloud computing is a virtualization based technology that reduces the cost of IT infrastructure. It provides a solution of IT infrastructure in low cost.
In this cloud tutorial, you will learn basics and advanced topics of cloud which is developed for beginners and professionals.
What is Cloud Computing
Cloud computing means on demand delivery of IT resources via the internet with pay-as-you-go pricing. It provides a solution of IT infrastructure in low cost.
Why Cloud Computing
Actually, Small as well as some large IT companies follows 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.
In that server room, there should be a database server, mail server, networking, firewalls, routers, modem, switches, QPS (Query Per Second means how much queries or load will be handled by the server) , configurable system, high net speed and the maintenance engineers.
To establish such IT infrastructure, we need to spend lots of money. To overcome all these problems and to reduce the IT infrastructure cost, Cloud Computing comes into existence.
Characteristics of Cloud Computing
The characteristics of cloud computing are given below:
The cloud works in the distributed computing environment. It shares resources among users and works very fast.
2) High availability and reliability
Availability of servers is high and more reliable, because chances of infrastructure failure are minimal.
3) High Scalability
Means "on-demand" provisioning of resources on a large scale, without having engineers for peak loads.
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.
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 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.
