PUBLIC CLOUD Public Cloud

A public cloud is basically the internet. Service providers use the internet to make resources, such as applications (also known as Software-as-a-service) and storage, available to the general public, or on a ‘public cloud. Examples of public clouds include Amazon Elastic Compute Cloud (EC2), IBM’s Blue Cloud, Sun Cloud, Google AppEngine and Windows Azure Services Platform.

For users, these types of clouds will provide the best economies of scale, are inexpensive to set-up because hardware, application and bandwidth costs are covered by the provider. It’s a pay-per-usage model and the only costs incurred are based on the capacity that is used.

There are some limitations, however; the public cloud may not be the right fit for every organization. The model can limit configuration, security, and SLA specificity, making it less-than-ideal for services using sensitive data that is subject to compliancy regulations.

BENEFITS OF PUBLIC CLOUD

Depending on the Internet for the storage and security of data resources is a common practice in today’s world. Public clouds, like any version of cloud offer numerous inherent benefits, such as these:

Scalable:

Cloud resources are typically available on demand, which means you can draw upon the cloud’s numerous online resources to any extent. However, because public cloud services are intended for open use by multiple consumers, companies will throttle speeds for individuals who utilize too many resources for too long.

Cost effective:

Public cloud services are typically available to consumers with the price tag of “free.” Online storage services give upwards of five gigabytes for free, with increased storage capacity at incredibly low monthly rates. Centralizing the operation and management of the server resources and sharing them across all cloud services offered helps reduce overall costs for the company.

Location Independent:

Public cloud services exist through the Internet, which means the cloud is accessible wherever the client is located.
