Shared-Nothing architecture: A Shared-Nothing Architecture (SN) is a distributed-computing architecture where each update request is satisfied by a single node such as a processor, memory or storage unit. The goal is to reduce contention among nodes. Nodes do not share memory. An alternative architecture share everything. Here all requests are satisfied through random combinations of nodes. Multiple nodes can try to access and update the same data simultaneously, therefore it may cause contention. SN prevents single points of failure and allows the system to continue working despite failures. A shared-nothing system divides its data among many nodes. Remote Direct Memory Access (RDMA): It is the technology for memory access on a remote machine without getting the operating system involved.

Shared-Nothing architecture:

A Shared-Nothing Architecture (SN) is a distributed-computing architecture where each update request is satisfied by a single node such as a processor, memory or storage unit.

The goal is to reduce contention among nodes.

Nodes do not share memory. An alternative architecture share everything. Here all requests are satisfied through random combinations of nodes.

Multiple nodes can try to access and update the same data simultaneously, therefore it may cause contention.

SN prevents single points of failure and allows the system to continue working despite failures.

A shared-nothing system divides its data among many nodes.

Remote Direct Memory Access (RDMA):

It is the technology for memory access on a remote machine without getting the operating system involved.
