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.

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.
