Public Cloud

Featured Image

“Cloud” has been marketed for the past several years; however, I find there is still confusion around the various flavors of “Cloud”.

A “public cloud” is a service in which a service provider makes resources, such as server computing, applications and/or storage available to the general public over the Internet.

Public cloud services are offered on a pay-per-use model. An individual or company can sign up for compute or storage resources, and pay for the number of hours or days they are using the computing and storage service.

The benefits of the public cloud is that it is relatively easy for an individual to provision server resources and is inexpensive to setup because the individual or company does not need to purchase any hardware, licensing, internet or storage. All of these components are provided by the cloud service provider. In addition, the public cloud service providers have lots of capacity of servers and storage, providing the individual or company using the cloud tremendous scalability – either up or down – as their needs change. Because you pay for what you use, there is no wasted investments in technology, giving you the ability to utilize the resources for a very short period of time, or longer period of time depending upon your requirements.

With a public cloud, you retain responsibility and management of the workload running in that public cloud. You setup your systems, make configuration changes, and bring down your systems independently. In a future blog we will review pricing models of the various options and things to make sure you understand and take into consideration when doing your analysis of various cloud options.

Public clouds provide companies and individuals an option that may be the most economic for certain workloads. It is important to review the workload and the capabilities of the public cloud provider as not all public clouds are equal. Doing an assessment of your workloads, your business requirements, security requirements and overall objectives for your project, will help identify if the public cloud model is the right fit for the specific project at hand. Other options to consider may be a private cloud, or a hybrid model whereby some of your workload utilizes the public cloud and other workloads utilize a private cloud or dedicated hardware.
