Different types of Clouds

by: Alexander Ostwalt

Every time you look into the sky what do you see? A white blob, or white line, or a white turtle with a rabbit sitting on top of it. Clouds can be many shapes and sized, similarly there are different types of clouds in cloud computing. 

The first type is a public cloud. Just like the name, this type of cloud is open to everybody and can be accessed by anybody on a public internet. A public cloud can be used as storage or service applications. Public clouds can also be shared between others, like in school, in a business, between friends, groups of people, and others. Overall a public cloud is a very convenient in everyday lives or when working on a group assignment, but it is not necessarily convenient with businesses or organizations.

Which brings us to the second type of cloud, a private cloud. Just like the public cloud it can be shared with others, but the only thing about a private cloud, it is shared between people that you only allow access to. Private clouds lets people share and exchange information between a group or a business. All these group or businesses can use or also have access to two different types of private clouds. 

One is on-premise private cloud is also known as a "Internal Cloud", which is used within an organization or a business servers. On-premise private cloud can only be accessed by the people in the business or an organization building that they are in. Compared to public cloud, an on-premised private cloud needs to be run on your own hardware, storage, networking, and a cloud software.  

The second private cloud is an externally hosted private cloud, this is where a third-party cloud provider creates and takes responsibility for implementing, securing, and managing the cloud. A externally hosted private cloud is good with organization or a business that wants to keep their data at an offsite or a different location, but prefer not to use a public cloud. 

Then finally for the third type of cloud which is a hybrid cloud. With this type of cloud you can maintain systems in a data in-house using the public cloud while using the external services of a private cloud where some part will be in a off-site location for some application and processes. With a hybrid cloud you can keep your private information on a private cloud, but with anything else you can use the public cloud. Hybrid clouds are preferred between businesses and organization because its the best of both clouds.
