What is Cloud Computing?

What is Cloud Computing? Cloud Computing often referred to as “the cloud”, in simple terms means storing or accessing your data and programs over the internet rather than your own hard drive.

Everything nowadays is moved to the cloud, running in the cloud, accessed from the cloud or may be stored in the cloud.

In 2006, Amazon Web Services (AWS) began offering IT infrastructure services to businesses in the form of web services—now commonly known as cloud computing. One of the key benefits of cloud computing is the opportunity to replace up-front capital infrastructure expenses with low variable costs that scale with your business. With the cloud, businesses no longer need to plan for and procure servers and other IT infrastructure weeks or months in advance. Instead, they can instantly spin up hundreds or thousands of servers in minutes and deliver results faster. Today, AWS provides a highly reliable, scalable, low-cost infrastructure platform in the cloud that powers hundreds of thousands of businesses in 190 countries around the world.

We now know about the service models, once you offer a service next comes deployment, let us now discuss the deployment models:

Public Cloud

Private Cloud

Hybrid Cloud

Let’s go ahead and see what advantages Cloud Computing serves:

Fast Implementation if you’ve been there for a development or implementation of an application, it takes sometimes months or even years to make the application up and running, with cloud you can cut through the time and make things faster.

Instant Scalability With cloud resources you can always scale up or scale down the no. of resources and users according to your need, the cloud capacity never runs out! Access Anywhere Applications built on cloud are designed to be accessed from anywhere, you just need an internet connection on a mobile device.

No Upfront Costs earlier to deploy an application you had to purchase the necessary hardware, build the architecture, purchase software licenses etc, but with cloud all those costs are dramatically reduced and in some cases eliminated.

Maintenance Free Traditionally you would have to patch your software with the latest releases, upgrade your hardware and also troubleshoot faults in your system at the hardware level, but with cloud you don’t have to worry about the maintenance of your hardware, it will all be managed by your cloud provider.

Better Security An Independent study found that yearly a medium scale company loses around 260 laptops, this is a loss to the company not in monetary terms, but the data that was there on the laptop is valuable, with Cloud you don’t have to worry about that, all your data is stored in a centralized secure location.
