Cloud computing is a general term for technologies that use (provide) huge information processing facilities in the world on the other side of the storage clouds. Cloud computing can be flexibly divided into three main types which are;
- SaaS: Software as a Service
- PaaS: Platform as a Service
- IaaS: Infrastructure as a Service
Software as a Service
Specific examples include the mail system provided by Google (Google Apps Mail) and the customer management system provided by Salesforce (CRM: which has a function to support sales activities). This makes it possible to install highly functional software from the same day without having to bother to prepare server facilities, procure necessary equipment, and install OS and email software.
Platform as a Service
Specific examples include Windows Azure provided by Microsoft and Force.com provided by Salesforce. By using these, you can immediately use the environment in which the OS and middleware (database, application execution environment, system management tools, etc.) are all set up. The difference between PaaS and SaaS lies in the limited software available. In SaaS, the software that users can use is limited to the software provided by IT service providers (Gmail, etc.). On the other hand, PaaS has an environment that is easy to develop in advance, so users can develop and use the software themselves relatively easily.
Infrastructure as a Service
IaaS is a service with a higher degree of freedom. As a specific example, Amazon’s EC2 is famous. It’s like a so-called rental server service (a service that provides an environment where the OS is set up on the server), but since EC2 uses virtualization technology, etc., it is customized to meet customer needs. You can set up the OS environment immediately. It seems that more than 1000 types of OS image files are prepared in advance, so there is no need to set up a server.
What thing is great about the Cloud Computing?
The best characteristics of cloud computing training in Abu Dhabi are its irresistible availability, broad range, and its cost-effective price. The maximum economics of scale by making full use of the latest technologies such as virtualization technology and technology of data distribution is the reason why cloud computing achieve high availability and high scalability at reasonable prices. It can be said that cloud computing can freely sell or buy advanced services that combine thousands of servers.
If cloud computing is used, it will be possible to secure and prepare hundreds of servers at once without making major changes to existing settings.
Another best thing about cloud computing is that it is really flexible and they are suitable for the firms which have growing bandwidth demands. The scale of the cloud can be increased according to the growth of your business. You can say that cloud computing has no boundaries and it can be adapted by any business with any scale. The high cost of the hardware can be eliminated by the cloud computing and you just need to subscribe and you are ready to use the cloud. If you are interested in making the future in cloud computing and security then it would be beneficial for you to have the CEH course in Middle East. This will give you the base of the Cloud Security and other tactics.
