Cloud computing, often referred to as simply “The Cloud” is the delivery of on-demand computing resources-everything from applications to data centers over the Internet on a pay-for-use basis. Whether you are supporting the critical operations of your business or running applications that share videos to millions of mobile users, “The Cloud” provides rapid access to flexible and low cost IT resources.
How Does it Work?
Cloud Computing provides a simple way to access servers, storage, databases and a broad set of application services over the Internet. Cloud Computing providers such as Microsoft, Amazon, IBM and Salesforce own and maintain the network-connected hardware required for these application services, while you provision and use what you need via a web application.
What are the benefits?
1. No More Upfront Capital Required – pay as you go. Instead of having to invest upfront in data centers before you know how you’re going to use them, you can only pay when you consume computing resources, and only pay for how much you consume. This eliminates need to make large upfront investments in hardware and software. It also frees your IT resources from spending a lot of time on managing that hardware and software. Instead, you can provision exactly the right type and size of computing resources you need to operate your IT department. You simply pay as you go and enjoy a subscription-based model that’s kind to your cash flow.
2. Flexibility, Agility – Eliminate guessing on your infrastructure capacity needs. Cloud-based services are ideal for businesses with growing or fluctuating bandwidth demands. You can access as much or as little as you need, and scale up and down as required with only a few minutes notice. This level of agility can give businesses using cloud computing a real advantage over competitors.
3. Cost Savings because of aggregated usage. Because cloud services providers like Microsoft and Amazon aggregate usage from hundreds of thousands of customers, by using cloud computing, you can achieve a lower variable cost than you can get on your own.
4. Enjoy More Fault Tolerance. Cloud providers can afford to have multiple data centers, multiple Internet connections at each data center, as well as replication of data between data centers. Plus, they can offer levels of data protection far beyond simple nightly backups, such as continuous data protection, generators to handle power outages, and high-end servers that can keep running even one component fails.
5. Focus your IT resources exclusively on what sets you apart. Since cloud services provider manages the infrastructure for you, you no longer have to worry about managing the servers, routers, load balancers and other IT systems – no more roll out regular software updates – including security updates. Now you can focus all your energy on projects that differentiate your business.
6. Go global, work from anywhere with just few clicks. With most cloud serviced provider like Microsoft and Amazon, you can easily deploy your application in multiple regions around the world and on any platform of your choice – PC, Android and iOS devices – with just a few clicks. The result – If you’ve got an internet connection you can be at work.
7. More Security. Lost laptops and smart phones are a billion dollar business problem. And potentially greater than the loss of an expensive piece of hardware is the loss of the sensitive data inside it. Cloud computing gives you greater security when this happens. Because your data is stored in the cloud, you can access it no matter what happens to your machine. And you can even remotely wipe data from lost devices so it doesn’t get into the wrong hands.
8. Easier Disaster Recovery and Back Up. Cloud computing offers a very cost efficient and effortless solution for a comprehensive data backup and disaster recovery process. With industry-leading encryption and security practices employed by leading cloud services provider, cloud-based data is highly secure.
