Nowadays, cloud computing is nothing new. The “cloud” changes our lives in many ways through accessing, analyzing, storing and sharing information. There are several kinds of “cloud” for use. They are public cloud, private cloud and hybrid cloud. But which one is the best and which one is right for you?

Public Cloud vs Private Cloud

When the services are rendered over a network that is open for public use, we call it a “public cloud”. Public cloud services may be free or offered on a pay-per-usage model. A private cloud is a particular model of cloud computing that involves a distinct and secure cloud based environment in which only the specified client can operate. Technically, there may be little or no difference between public and private cloud architecture, however, security consideration may be substantially different for services (applications, storage, and other resources). The following picture shows the difference between public cloud and private cloud from four respects.

Hybrid Cloud

According the the definition, hybrid cloud is a composition of two or more clouds that remain distinct entities but are bound together, offering the benefits of multiple deployment models. Hybrid cloud can also mean the ability to connect collocation, managed and/or dedicated services with cloud resources. There are some challenges that need to be considered during the planning and design phase of hybrid cloud. The biggest challenge is the integration of the different cloud services and technologies. Though there still too much challenges to hybrid cloud, the future of hybrid cloud seems to be bright and we have a lot to look forward to. In fact, hybrid cloud is slated to be the ultimate end-state for the enterprise as it provides maximum benefits for minimal costs, and can be integrated with current cloud environments used by businesses.

Depending on the type of data you’re working with, you can choose public cloud, private cloud, or hybrid clouds in terms of the different levels of security and management required. But when it comes to the cloud, a hybrid cloud may be the best as it provides the most stable foundation for the future.
