Dear doctor
I chose the following quotation hoping illustrate the question
"A distributed cache is a system that pools together the random-access memory (RAM) of multiple networked computers into a single in-memory data store used as a data cache to provide fast access to data. While most caches are traditionally in one physical server or hardware component, a distributed cache can grow beyond the memory limits of a single computer by linking together multiple computers–referred to as a distributed architecture or a distributed cluster–for larger capacity and increased processing power.
Distributed caches are especially useful in environments with high data volume and load. The distributed architecture allows incremental expansion/scaling by adding more computers to the cluster, allowing the cache to grow in step with the data growth.
A distributed cache pools the RAM of multiple computers into a single in-memory data store used as a data cache to provide fast access to data.
With a distributed cache, you can have a large number of concurrent web sessions that can be accessed by any of the web application servers that are running the system. This lets you load balance web traffic over several application servers and not lose session data should any application server fail."
