Cloud computing removes all the crunching and processing of your data from your laptop, desktop or mobile device and moves it to massive computer clusters far away in cyberspace. You can access them using the use of a web browser, or an app, wherever you have an Internet connection.
Businesses can cut down on their infrastructure and hardware costs by moving to the cloud. They only pay for what they actually use. It also frees up IT personnel to focus on more strategic projects. Also, by removing the necessity to continually update and maintain internal systems, it helps companies to accelerate their efforts to make the most of new opportunities in business.
Significant developments in virtualization and distributed computing and the availability of high-speed Internet connections, have increased the demand for cloud computing. For many companies it’s the only way to keep up with customer demands, increase agility and expand.
There are three types of cloud services:
Public cloud services are managed and maintained by third-party service providers. They provide flexibility, cost savings and performance advantages. They also permit rapid capacity expansion or reduction if needed. This model is more risky, which require continuous, attentive management.
Private cloud services are maintained and managed by the organization. They provide a higher degree of control but come at a cost of increased complexity, cost and maintenance requirements. A good set of tools and experience is essential to architect, build and manage a private cloud to achieve business objectives.
