It's made life very easy. Now, a lot of things are very automated. 

The product is very well-designed. It is easy to use, and it is very cost-effective.  

Well, I've been at two different companies and mostly I'll relate to my experience at HLI, Human Longevity, in San Diego. We used it for genomics. Genomics is a perfect use case for big data. We manage literally terabytes of data using some of the tools that are included with EMR like Spark and Hive. What we were able to do with these EMR tools - EMR is a collection of things - was to essentially set up a genomic data warehouse of people's samples and their sequenced DNA. And then we were able to quickly and easily pair that with annotation data which essentially just tells you what your genome means, like what that sequence, or what certain sections of those characters, means. That was just all very, very easy and it allowed everyone to know where, for instance, the most recent versions of certain data lived at all times, which is really important.

Less expensive than in-house hosting, much more scalable when needed to process larger volumes of data.

It's helped to automate processes. It's also provided quick deployment, and faster processing.
