There is no second thought that cloud computing is changing the IT landscape at a fastest stride, helping them to leverage on-demand resource provisioning, self-service capability, broad network access, and pay-per-use billing pattern. Now, let’s try to understand these terms: Virtual Data Center: A virtual DC is an extensive pool of computing resources (CPU, memory, storage, bandwidth, etc.) that are designed to meet specific business requirements. In the context of cloud computing, VDC falls within Infrastructure-as-a-Service (IaaS). A virtual data center concept overcomes ‘one server per application’ which often leads to underutilized resources. VDC helps in meeting dynamic business needs by ascertaining effective resource management and utilization. By consolidating IT architecture, it enables businesses to move from Cap-Ex to Op-Ex model. Cloud Data Center: Well, cloud data centers are constructed to serve multiple purposes with homogeneous hardware environment. It comprises standardized software architecture and management tools. When compared to traditional data centers, cloud data centers are easy to manage, operate and are scalable. It enables businesses to quickly provision resources as per the changing business demands. Private Cloud: It is one of the cloud computing models, which is hosted within an organization giving more control and power to the business’s IT professionals. Technically, a private cloud architecture is setup on the capabilities that virtualization offers. Private cloud model bestows multifold benefits including self-service, and automation that enables users to quickly provision and launch new virtual machines (VMs) without intervention of IT. On the top of it, private cloud also comprises reporting and chargeback attributes that automatically tracks computing resources utilization and bill the VM owners depending on their utilization. |
