Cloud Computing What You Need to Know - Part 1 (The basic about Cloud Computing)

Started from this week onward, I will write more on Cloud Computing information, I will post more on the Cloud Computing concept and especially for those who interested to take Comptia Cloud Essentials Examination :

I will go through part by part and will try to write as much as I can so that my future students who interested to join my Cloud Computing training will have an idea what is Cloud Computing all about.

Lets get started...

On this Part 1 of Cloud Computing, let see the basic about Cloud Computing..

Cloud Computing is an internet- based computing solution that delivers IT as a service.

Hardware and software share resources and configured to work together providing applications their collective computing power, with the illusion of running on a single system.

Imagine massive bunch of computers linked through high-speed networks where large numbers of discrete organizations can store their applications and data on a pay-as-you-go model.

There are 3 types of Cloud Computing :

-- Public Cloud : based on the standard cloud computing model, in which resources, such as infrastructure including servers, storage and even applications are made available to the general public over the Internet, by a cloud service provider.

Examples of public clouds are, Amazon Elastic Compute Cloud (EC2), IBM's Blue Cloud, Google AppEngine and Windows Azure Services.

-- Private Cloud : infrastructure that is used only for a single organization, whether handled internally or by a 3rd-party and hosted internally or externally. The private cloud is a new method of computing in which corporate IT infrastructure is present as a ubiquitous, easily accessible, and reliable utility service. Business owners and application owners, who want to use a new business service, can use the infrastructure as a standard service, without understanding the complexities of servers, storage, and networks.A private cloud, or a virtual private cloud, is a type of cloud computing infrastructure created for in-house datacenter use.

-- Hybrid Cloud : Cloud computing environment comprised of at least one private cloud and at least one public cloud. With this model, an organization typically manages applications with sensitive data in-house, but may choose to store archived or non-sensitive data with a cloud provider.

That's all for now... wait for my Part 2 - Cloud Computing benefits...
