Database downtime can hurt or doom any company with anything to do with the internet. Load balancing : Traffic is distributed across multiple servers to prevent any one component from becoming overloaded. Load balancers can detect when a component is not responding and put traffic redirection in motion.

In both cases, when using virtually-synchronous replication, the process will require certification from each node and local (by node) write; as such, the number of writes is NOT distributed across multiple nodes but duplicated. It will also allow us to redirect read/write traffic to the primary and read-only traffic to all secondaries.

It helps assess how a site, web application, or API will respond to various traffic, without adding any additional infrastructure. Executing an internal test can tell you how well your application or site handles an increase in traffic, but it will never reflect real-world conditions.

Queueing theory is the mathematical study of waiting lines, both real and virtual. The internet may change, and web pages may grow and evolve, but user expectations are constant. Our everyday lives are filled with events – from sitting in traffic to standing in line at the grocery store – that challenge our need for flow.

For example, you can think of a cell phone network as a type of distributed system, consisting of a network of internet-connected devices that share resources workload. Peer-to-Peer.
