  2. What is Shared Nothing architecture? • It is a distributed architecture in which each node is independent and self sufficient, and there is no single point of contention across the system. • None of the nodes share processing, memory, or storage resources.

  4. Shared DiskArchitectureExample

  5. Properties of Shared Nothing • Scalability • A pure Shared Nothing system can scale almost infinitely simply by adding nodes in the form of inexpensive computers, since there is no single bottleneck to slow the system down • Data partitioning • Data is typically partitioned among many nodes on different databases • This can lead to performance issues when/if data on many nodes needs to be operated on. • No single point of failure

  6. Who uses Shared Nothing? • The web • Shared Nothing Architecture is popular in web development due to its lost cost of entry and scalability • Data warehousing • Shared Nothing Architecture allows for large databases with low cost, high performance, and high scalability.
