Cloud Cube Model
What is Cloud Cube Model?
The Cloud computing model is developed by the Jericho forum. It helps to classify the network of cloud-based on the four-dimensional factor: Internal/External, proprietary/open, de-perimeterized/ perimeterized, and insourced/ outsourced.
Now, let’s discuss the cloud cube model.
Introduction to Cloud Cube
The Cloud cube model helps to categorize the network of cloud-based on the four-dimensional factor. The main motive of the cloud model is to secure and protect the cloud network. The cloud model supports to choose cloud creation for the security association. It also helps IT managers, organizations, and business leaders by offering a safe and protected network.
Security is an essential aspect for cloud users, and most of the cloud providers understand it. The customer should also take care of that; the selected cloud formation fulfills the regulatory and location needs. They also need one thing in their mind that if cloud providers stop offering the services, where else they can move.
There are three service models which consists of:
- SaaS
- PaaS
- IaaS
There are four deployment models also.
- Public cloud
- Private cloud
- Community cloud
- Hybrid cloud
The models are flexible, user-friendly, and offer many benefits to cloud users.
The following figure shows the cloud layers when the clouds operates.
How is Data Secured in the Cloud Cube Model?
There are various steps and points you should keep in your mind while securing your data in a cloud cube model.
- The categorization of the data, the user must know what rules must be applied to secure and protect it.
- It should make sure that the data exist only in particular trust levels.
- It should examine that what regulatory compliance and constraints are applicable. For example: - The data is kept in a specific limit and whether it has to stay in the secure harbor or not.
When the data is categorized and can put in the needed zone, the assigned person is in a position to decide the following aspects-
- The processes and data, which are to be shift in the cloud.
- At what level the customer wants to operate in the cloud. Maybe it is infrastructure, platform, and software.
- The cloud formations fulfill the requirements.
- In a cloud, the level of operation can be different as per the requirement.
The following figure shows the cloud layers, where the cloud operates:
Dimensions of Cloud Cube Model
There are following four dimensions in the Cloud cube model.
- Internal/External
- Proprietary/open
- De-perimeterized/perimeterized
- Insourced/outsourced dimension
Internal/External: - Internal/External is the most common form of the cloud. It describes the physical location of the data. It agrees whether the data exists inside or outside of your organization’s limit. In this, the data that is stored by the help of private cloud deployment will be referred to as internal, and the data outside the cloud will be referred to as external.
Proprietary/Open: - The second dimension of cloud formation is proprietary/open. It defines the state of ownership of the cloud technology and interfaces. It also defines the level of incomparability while enabling data transportability between the system and forms of cloud.
The meaning of proprietary dimension means that the organization is offering the service in a secure and protected manner under their ownership.
The open dimension using such type of technology in which more suppliers are allowed. In addition to that, the user is not constrained in being able to share the data and cooperate with selected partners using open technology.
De-perimeterized/Perimeterized: - To reach de-perimeterized/perimeterized form, the user requires Jericho forum and collaboration oriented architecture commandments. It defines whether you are working inside your traditional mindset or outside it.
The meaning Perimeterized dimension is continuing to work within the traditional boundary, orphan signaled by network firewalls. With the support of VPN and the operation of the virtual server in your IP domain, the customer can expand the organization’s boundary into the external cloud computing domain.
De-perimeterized is the system which is designed on the principles outlined in the Jericho forum’s commandments. In this, data is encapsulated with metadata and structure, which will again support to secure the data and control the inappropriate usage.
Insourced/Outsourced: - Insourced/outsourced is the fourth dimension of the cloud cube model. In the outsourced dimension, services are offered by the third party, and in the insourced dimension, the services are offered by the own staff.
In some organizations with traditional bandwidth software or hardware, providers will run smoothly when they become cloud service providers.
Organizations exploring to process cloud services should have the capability to set a legally binding collaboration agreement. In this, an organization must ensure that the data is removed from the service provider’s infrastructure.
