What is Cloud Computing ?

Simply put, cloud computing is the delivery of computing services—servers, storage, databases, networking, software, analytics, intelligence and more—over the Internet (“the cloud”) to offer faster innovation, flexible resources, and economies of scale. You typically pay only for cloud services you use, helping lower your operating costs, run your infrastructure more efficiently, and scale as your business needs change

Benefits of Cloud Computing

Cost Effective

Perhaps, the most significant cloud computing benefit is in terms of IT cost savings.  With cloud computing, you can save substantial capital costs with zero in-house server storage and application requirements. The lack of on-premises infrastructure also removes their associated operational costs in the form of power, air conditioning and administration costs. In fact, Cloud services are extremely affordable for smaller businesses.

Reliable

With a managed service platform, cloud computing is much more reliable and consistent than in-house IT infrastructure. Most providers offer a Service Level Agreement which guarantees 24/7/365 and 99.99% availability. Your organization can benefit from a massive pool of redundant IT resources, as well as quick failover mechanism – if a server fails, hosted applications and services can easily be transited to any of the available servers.

Secure

Many cloud providers offer a broad set of policies, technologies, and controls that strengthen your security posture overall, helping protect your data, apps, and infrastructure from potential threats.

Performance

The biggest cloud computing services run on a worldwide network of secure datacenters, which are regularly upgraded to the latest generation of fast and efficient computing hardware. This offers several benefits over a single corporate datacenter, including reduced network latency for applications and greater economies of scales.

Manageability

Cloud computing provides enhanced and simplified IT management and maintenance capabilities through central administration of resources, vendor managed infrastructure and SLA backed agreements. You enjoy a simple web-based user interface for accessing software, applications and services – without the need for installation – and an SLA ensures the timely and guaranteed delivery, management and maintenance of your IT services.

Speed

Most cloud computing services are provided self service and on demand, so even vast amounts of computing resources can be provisioned in minutes, typically with just a few mouse clicks, giving businesses a lot of flexibility and taking the pressure off capacity planning.

How Cloud Computing works??

In a cloud computing system, there’s a significant workload shift. Local computers no longer have to do all the heavy lifting when it comes to running applications. The network of computers that make up the cloud handles them instead. Hardware and software demand on the user’s side decrease. The only thing the user’s computer needs to be able to run is the cloud computing system’s interface software, which can be as simple as a Web browser, and the cloud’s network takes care of the rest.
There are several factors that set cloud computing technology attractive for business use. For starters, cloud computing technology provides a managed service so you can just focus on whatever task you’re doing that’s supported by the service.

When using your “local” version of Microsoft Word, you have to go into the program’s preferences and specify you want versions of your files to be periodically saved. Once you’ve done that, you can breathe easy knowing that, if you have a sudden power outage or other crisis that results in lost work, you’ll at least have a version of your file that was saved within the last few minutes. Even then, there’s always the chance your hard drive might crash, causing you to lose your work, despite taking the time to tweak settings so your versions are automatically saved.

However, when using a cloud-based word processor, everything you type is automatically saved in the cloud every few seconds. There’s no need to fiddle with settings to make sure work gets saved, or to designate a folder on your computer to store the saved content. The managed nature of cloud-based services like Google Drive allows users to simply enjoy the benefits of the technology they’re using and feel confident the service provider will take care of things like file saving and storage.

Many cloud computing services are available on-demand and are quite scalable. If your needs vary from one month to the next, its likely you can simply pay more or less depending on how your usage changes. Traditionally, there was always the risk of buying a pricey computer network and realizing it was larger than you needed, or perhaps discovering that the setup you have is much too small for what you’re trying to do. Cloud computing makes these scenarios less likely because you may subscribe to most cloud computing services without getting locked into lengthy contracts.
