The concept of cloud computing started with ISP on a large scale, such as Amazon AWS, Google, Microsoft and others who built their own infrastructure. From among them emerged architecture: a system of distributed horizontally, introduced as a virtual IT service massively scaled and held as pooled resources configured and continuously. This model was introduced in October 2006 by George Gilder.
The farm on which he wrote Gilder, were similar in architecture to process “grid”, but while networks are utilized for technical processing applications loosely coupled (loosely coupled), a system composed of subsystems with some autonomy of action, maintaining a continuous relationship between them, and this cloud model was applied to the Internet services.
The security in cloud computing is quite strong. Network integration services proven by their nature, the cloud computing can be integrated much more easily and quickly with the rest of their enterprise applications (be it traditional software or cloud computing infrastructure), whether developed internally or external. Cloud computing provide services worldwide. The cloud computing infrastructure provides greater resilience, disaster recovery, complete and minimizing downtime.
100% infrastructure cloud computing allows the content provider or cloud services without installing any hardware, as this is provided by the supplier of the infrastructure or the platform in the cloud. The best part of cloud computing is it’s highly simplicity and it requires much less investment to get started.
It has faster implementation and with less risk. You can certainly get started very quickly with the cloud computing extensive infrastructure. Moreover, you do not have to wait for years and also you don’t have to invest large sums of money before a user logs on for a new solution. The applications in cloud computing will be available within days or hours instead of weeks, even with a considerable level of integration or customization.
Automatic updates do not adversely affect IT resources. If we update it to the upgraded version, then we will have to devote resources and time to recreate our integration’s and customization The cloud computing technology does not require him to decide whether to upgrade and keep your job, because these customization’s and integration’s are maintained automatically during the upgrade process.
Cloud computing certainly contributes towards the adept utilization of the energy. In data centers, the servers consume a large amount of energy than the required amount. As a matter of fact, in the clouds, the energy used is very efficient, hence reducing the wastage of the energy to a greater extent.
Cloud computing has these advantages which are based on a high dynamic IT infrastructure which is characterized with rapid mobilization of resources, high degree of automation, high adaptability in order to meet variables and flexible pricing and advanced virtualization according to consumption also made preventing the misuse of the software and piracy.
To ensure the coordinated work of the computer network of nodes on the side of the cloud provider uses specialized middle ware that provides status monitoring hardware and software, load balancing, providing resources to address the problem.
