Introduction Cloud computing is on the rise for a couple of reasons: it is flexible, relatively cheap compared to supporting in-house infrastructure, and it allows excellent automation of resource allocation, thus cutting costs even more. Cloud computing also allows horizontal scalability, which is crucial for many businesses in today’s digital age. When the amount of data to be processed grows year to year, one cannot rely on old-fashioned vertical scalability models buying more and more expensive servers. In this era of distributed computing, data should be spread across multiple cheaper a system called cluster where data can be stored reliably, processed and returned to the user when needed. Building such systems isn't an easy task, but luckily there are solutions that fit perfectly into cloud architecture. I'm talking about Apache Ignite.
