Here is where In-memory technology has gained significant traction over the years

It is exciting to experience that, accessing data from the in-memory database eliminates the seek time when querying the data, providing faster and more predictable performance. 

Applications that need fast response time such as telecommunications networks, and mobile advertising networks, most often resort to the use main-memory databases. 

In-memory technology has gained significant traction over the years, especially in the data analytics space, majorly due to the multi-core processors capable of addressing large memory and also due to availability of less expensive RAM.
