We’ve attempted to clear those doubts with the help of this story, in which we’ve given a mix of both theory and practice. Before you dive into the story, here are a few things that you must know about Cloud Computing:
There’s more to Cloud Computing than a few Internet based services
Cloud Computing is more than a few applications you can access over the Internet. It allows you to buy hardware resources online, take an entire platform for software development, or setup a platform yourself inhouse.
Cloud Computing is a fundamental shift from how your current IT infrastructure is configured
Most of the time, when people talk about cloud computing, they refer to the public cloud and some apps you can use from it. But there’s a lot more to cloud computing than procuring a few online services. It’s a fundamental shift from the traditional client/server architecture. Instead of having multiple servers, and even clients, all over the place, they’re all consolidated into fewer, powerful machines. That’s going back to the mainframe days, you might say, but back in those days, you didn’t have mobile users carrying laptops, netbooks, and smartphones, with Internet access. So Cloud Computing is how your IT infrastructure will change in the near future, to become more flexible, agile, efficient, cost effective, and accessible from anywhere. This sort of tuning will require careful planning, and would need to be done gradually in multiple phases over a period of time.
Cloud computing is about reducing wastage of IT resources & utilizing them more effectively
Whether it’s the service provider’s cloud, or your own, it’s all about utilizing your IT infrastructure more effectively. Most cloud applications are built upon virtualization of hardware resources. While virtualization let’s you use the hardware more effectively, other tools let you do the allocation and de-allocation of resources dynamically. Cloud computing to users is what electricity is to consumers When you plug an electrical or electronic device into a wall outlet, you expect the device to work. You’re not concerned about how electricity is generated at the back-end. This in a nutshell, is what cloud computing is supposed to do to your IT infrastructure. Why should users have to know the complexities of the IT infrastructure at the back-end? They should be able to access the services seamlessly without any glitches.
Cloud computing does not equal the Cloud
While the cloud is typically another name for the Internet, cloud computing is goes much beyond that and defines your IT infrastructure. There are three models of cloud computing-public, private, and hybrid, and three different ways of implementing them-SaaS, PaaS, and IaaS. All these have been explained elsewhere in this story. In this story, we’ve covered everything you need to know before you decide to move to the cloud.
