Cloud Computing Myths Debunked...

Hi friends I got a great information about cloud computing....it talks about how Amazon Web Services has debunked the myths about cloud computing..


As the 5th International Cloud Computing Conference & Expo (Cloud Expo) opens in New York City on April 19, Amazon Web Services (AWS) is tapping into the attention the event is placing on cloud computing to address some of what the company views as the more persistent myths related to the cloud.


Myth 1: The Cloud Is Not Reliable

Setting the tone for his argument, Selipsky first laid out the landscape. He noted that chief information officers (CIOs) in enterprise organizations have tough jobs and often are responsible for several thousand applications. They very much feel on the hook for the performance and security of these applications. And, when there are problems, they are used to walking down the hall or picking up a phone and choking their own person. There’s a certain comfort in knowing you can take some action if there is a problem. And, relinquishing that control and ability to scurry and take action is understandably difficult.


Myth 2: Security and Privacy Are Not Adequate in the Cloud

Security is an end-to-end process and companies need to build security at every level of the stack, Selipsky said. Examining Amazon’s cloud, you will see that the same security isolations are employed as would be found in a traditional data center, he said. These include physical data center security, separation of the network, isolation of the server hardware, and isolation of storage. On the physical data center side, well before Amazon launched its cloud services, data centers had already become a frequently shared infrastructure.


Myth 3: I Can Get All the Benefits of the Cloud by Creating My Own In-house Cloud or Private Cloud

“There’s a lot of marketing going on about the concept of the ‘private cloud,’” Selipsky said. “We think there’s a bit of a misnomer here.”

In general, “we often see companies struggling to accurately measure the cost of infrastructure,” he said. “Scale and utilization are big advantages for AWS. In our opinion, a cloud has five key characteristics: It eliminates capex; allows you to pay for what you use; provides true elastic capacity to scale up and down; allows you to move very quickly and provision servers in minutes; and allows you to offload the undifferentiated heavy lifting of infrastructure so your engineers work on differentiating problems”


Myth 4: If I Can’t Move Everything at Once, the Cloud Isn’t for Me

“We believe this is nearly impossible and ill-advised,” Selipsky said. “We recommend picking a few apps to gain experience and comfort then build a migration plan. This is what we most often see companies doing.”

Moreover, added Selipsky, “Companies will be operating in hybrid environments for years to come. We see some companies putting some stuff on AWS and then keeping some stuff in-house. And I think that’s fine. It’s a perfectly prudent and legitimate way of proceeding.”



Myth 5:  Cost Is the Biggest Driver of Cloud Adoption

“There is a big savings in capex and cost but what we find is that one of the main drivers of adoption is that time-to-market for ideas is much faster in the cloud because it lets you focus your engineering resources on what differentiates your businesses.”
