Types Of Cloud Computing
Cloud computing is the delivery of on-demand IT resources over the internet. This article will help you clear the basic concepts of Cloud computing. There are 4 different types of cloud computing.
- Public cloud
- Private cloud
- Community cloud
- Hybrid cloud
These types differ on the basis of implementation type, hosting type and who has access to it. All types are based on the same principle of Virtualization but differ in terms of location, storage capacity, accessibility, and more. Depending on the type of data you are working with.
Public Cloud
The name speaks for itself: public clouds are available to the general public, and data are created and stored on third-party servers.
The Advantages of a Public Cloud
- High scalability
- Cost effective
- Easy to manage
- Highly reliable
- No geographical restrictions
The Disadvantages of a Public Cloud
- Not considered the safest option for sensitive data
Private Cloud
There is little to no difference between a public and a private model from the technical point of view, as their architectures are very similar. However, as opposed to a public cloud that is available to the general public, only one specific company owns a private cloud. The server can be hosted externally or on the premises of the owner company.
The Advantages of a Private Cloud
- Improved level of security
- Customizable
- Greater control over the server
The Disadvantages of a Private Cloud
- Harder to access data from remote locations
- The major disadvantage is its cost
Community Cloud
This type largely resembles the private one; the only difference is the set of users. Whereas only one company owns the private cloud server, several organizations with similar backgrounds share the infrastructure and related resources of a community cloud.
The Advantages of a Community Cloud
- Cost reduction
- Improved security, privacy and reliability
- Ease of data sharing and collaboration
The Disadvantages of a Community Cloud
- High cost compared to the public deployment model
- Sharing of fixed storage and bandwidth capacity
Hybrid Cloud
A hybrid cloud encompasses the best features of the public, private and community cloud. It allows companies to mix and match the facets of the three types that best suit their requirements.
The Advantages of a Hybrid Cloud
- Improved security and privacy
- Reasonable price
- Enhanced scalability and flexibility
The Disadvantages of a Hybrid Cloud
- Communication in network level may be conflicted as it’s used in both private and public clouds.
