Business Benefits of Cloud Computing and the Dynamic Data Center
Cloud computing incorporates virtualization, data and application on-demand deployment, online delivery of services and open source software to provide significant business benefits. Through virtualization, cloud computing allows a dynamic data center where servers provide resources that are utilized based on demand. As demand changes, resources ramp up or down dynamically in order to meet the growing or shrinking workload. Cloud applications may replace common IT services, such as file serving, messaging, CRM, storage and more.
The advantages of rolling out applications using cloud computing include reducing run time and response time, minimizing the purchasing and deployment of physical infrastructure. Considerations for energy savings, flexibility, simplified systems administration, consumption-based pricing, and maximizing the footprint of the data center make the case for cloud computing even more appealing.
Pay-by-use cloud computing
For smaller organizations in particular, where tighter budget, floor space issues and generalist IT staff are common, pay-by-use, or public, cloud computing yields significant business advantages. Layered service providers offering cloud-based solutions can be adjacent to company's equipment leases. These types of clouds are run by third-party service providers and applications from various customers could be mixed together on the cloud's servers, storage systems and networks.
* Expense-based, reduced capital outlay
* Always-current software licensing
* Automated software and security updates
* Robust, automated disaster recovery policies * Reduced technology asset management issues
* Less hardware to recycle
* Eliminates depreciable expenses
* Add/reduce capacity and capabilities as required
Private and hybrid cloud computing
Private cloud computing can be provided using an enterprise data center's own servers. Private clouds are built for the sole use of one client, providing the utmost control over data, security and quality of service. Private clouds can also be created and run by a company's own IT staff. The combination of virtual machines and virtual appliances used for server deployment objects is a key features of cloud computing. Also, organizations can merge a storage cloud that provides a virtualized storage platform and is managed through an API, or web-based interfaces for application data deployments and file management. Hybrid clouds utilize both public and private cloud models, which may be used to handle planned workload spikes or storage cloud configurations. Dedicated audits for security policies are a must. * Greater data security and control * Better manage quality of service * Leverage existing infrastructure and staff * Permits use of hybrid cloud services to augment private cloud capabilities.
