Introduction
Cloud computing is a computing paradigm, where a large pool of systems are connected in private or public networks, to provide dynamically scalable infrastructure for application, data and file storage.
With the advent of this technology, the cost of computation, application hosting, content storage and delivery is reduced significantly.
Cloud computing is a practical approach to experience direct cost benefits and it has the potential to transform a data center from a capital-intensive set up to a variable priced environment.
Ideas
The idea of cloud computing is based on a very fundamental principal of „reusability of IT capabilities'.
The difference that cloud computing brings compared to traditional concepts of “grid computing”, “distributed computing”, “utility computing”, or “autonomic computing” is to broaden horizons across organizational boundaries.
Cloud formations
Public clouds are available to the general public or a large industry group and are owned and provisioned by an organization selling cloud services.
Private clouds exist within your company's firewall and are managed by your organization.
Hybrid clouds are a combination of the public and the private cloud using services that are in both the public and private space.
Benefits
REDUCED COST:
The billing model is pay as per usage; the infrastructure is not purchased thus lowering maintenance. Initial expense and recurring expenses are much lower than traditional computing.
INCREASED STORAGE:
Sudden workload spikes are also managed effectively & efficiently, since the cloud can scale dynamically.
FLEXIBILTY:
Cloud computing stresses on getting applications to market very quickly, by using the most appropriate building blocks necessary for deployment.
CHALLENGES
DATA PROTECTION:
Data Security is a crucial element that warrants scrutiny.
Losing data to competition and the data confidentiality of consumers.
Actual storage location is not disclosed .
Firewalls across data centers (owned by enterprises) protect this sensitive information.
Service providers are responsible for maintaining data security and enterprises would have to rely on them.
Conclusion
Cloud computing can provide organizations with needed to ensure financial stability and high quality service.
There must be global cooperation if the cloud computing process is to attain optimal security and general operational standards.
With the advent of cloud computing it is imperative for us all to be ready for the revolution.
