A. B. C. D.D.
Cloud environments lack the ability to physically separate resources like a traditional data center can.
To compensate, cloud computing logical segregation concepts are employed.
These include VLANs, sandboxing, and the use of virtual network devices such as firewalls.
In a cloud environment, multitenancy refers to the ability of a cloud provider to host multiple customers, known as tenants, on the same physical infrastructure, while ensuring that each tenant's data and resources remain segregated and isolated from each other.
Compared to a traditional data center model, a cloud environment requires a different approach to resource segregation and separation due to the shared nature of the infrastructure.
The following are the types of segregation and separation of resources that are needed in a cloud environment for multitenancy purposes versus a traditional data center model:
A. Virtual: Virtual segregation involves the use of virtualization technologies to create separate virtual machines or containers for each tenant. This approach ensures that each tenant's resources are isolated from other tenants on the same physical server, preventing any potential breaches or performance issues from affecting other tenants.
B. Security: Security segregation involves the implementation of security measures such as access controls, firewalls, intrusion detection and prevention systems, and encryption to protect each tenant's data and resources from unauthorized access, theft, or modification.
C. Physical: Physical segregation involves the use of physical barriers such as cages, racks, and cabinets to physically separate the hardware infrastructure of each tenant. This approach is more common in traditional data center models where tenants have their own dedicated hardware.
D. Logical: Logical segregation involves the use of network and storage partitioning to ensure that each tenant's data and resources are logically separated from each other. This approach is often used in combination with virtual segregation to provide an additional layer of isolation and security.
In summary, a cloud environment requires virtual and security segregation to ensure multitenancy purposes, whereas traditional data centers rely more on physical and logical segregation to provide resource separation.
