The Cloud and Cloud ComputingCloudCloud Computingjust more buzzwords?The BasicsIn a 2008 interview, Oracle CEO, Larry Ellison was asked about the cloud and he responded with a three minute rant about cloud computing
What the h*ll is Cloud Computing?Oracle CEO Larry Ellison, 2008
Maybe I'm an idiot, but I have no idea what anyone is talking about. What is it? It's complete gibberish. It's insane. When is this idiocy going to stop? *Oracle CEO Larry Ellison, 2008
This year Larry Ellison announced Oracle is building a cloud service to host many of its key software products, including Java, database, middleware and CRM.
During that same announcement he also warned: Beware of false clouds.
So, who can define the cloud?Webopedia.com says:Cloud computing relies on sharing computing resources rather than having local servers or personal devices to handle applications. The goal of cloud computing is to apply traditional supercomputing, or high-performance computing power, normally used by military and research facilities, to perform tens of trillions of computations per second, in consumer-oriented applications such as financial portfolios or even to deliver personalized information, or power immersive computer games.
So, Cloud Computing is when we use someone elses computing power to perform tasks that my less powerful computer might struggle with?
YES!Wikipedia.com says: Cloud computing is the delivery of computing as a service rather than a product, whereby shared resources, software, and information are provided to computers and other devices as a utility over a network (typically the Internet).
Cloud Computing is you, me, our company, our community, using someone else's software or hardware or both over (usually) the internet?
YES!!Public Cloud Private Cloud whats the difference?Public Cloud describes cloud computing in the traditional mainstream sense, whereby resources are dynamically provisioned to the general public on a fine-grained, self-service basis over the Internet, via web applications/web services, from an off-site third-party provider who bills on a fine-grained utility computing basis.think Amazon Web Services.
Private Cloud is infrastructure operated solely for a single organization, whether managed internally or by a third-party and hosted internally or externally.
Hosted INFOR EAM would be considered a private cloud. There are layers of Cloud ComputingSaaS: Software as a Service a means of delivering software and its associated data over the internet.
IaaS: Infrastructure as a Service a provision model in which an organization outsources the equipment used to support operations, including servers, hardware, storage and networking components. The service provider houses the equipment and is responsible for housing, running and maintaining it.
PaaS Platform as a Service is an outgrowth of SaaS and can be a combination of SaaS and IaaS. As in the IaaS model, the service provider houses the equipment and is responsible for running and maintaining it and also provides operating systems, storage and network capacity over the internet. Heres the down-side of the cloud public and privatesometimes, it breaks.

One thing about the cloudNow, lets talk about a great example of the Public Cloud: Amazon Web ServicesHow many shop amazon.com?
How many are prime customers with access to Amazon Cloud Player music, movies, television and Amazon Cloud Storage?
Is anyone using Amazon Web Services?A show of handsElastic scale up resources or bring resources down as needed.
Quick Scaling new hardware can be brought online in minutes.
Flexible no long-term commitment to resources.
Building Blocks IT resources are provided as individual, separately priced building blocks. You can choose to use one, some, or all of the services AWS provides.
Experimentation if you have an idea youd like to try out, you can temporarily access the needed resources without making a long-term commitment. Then de-allocate resources when your experimentation is complete.
Why use Amazon Web Services?On a small scale, you can create a few static web pages or a small site for free.*
Larger companies might use AWS for disaster recovery, training, demos, data storage, overflow processing, regions and zones.
* http://aws.amazon.com/free/Amazon Web Services: as much or as little as you needAWS is a pay-as-you-go web service and there is a separate charge for each service you use.
Like the electricity at your home, AWS usage is metered. You pay a monthly fee based on how much youve used.
There is an AWS Simple Monthly Calculator to help estimate the cost.*
Some of the pricing dimensions that AWS uses:
* Time an hour of CPU time * Volume a gigabyte of transferred data * Count number of messages queued * Time and Space a gigabyte-month of data storage
