These issues are condensed into the “Three Vs” of managing big data: Volume, velocity, and variety. (more…)

What are Containers?

Scalability, high availability, containers, fault tolerance and eventual consistency. Tech terms can be confusing to those new to server administration or development. In the coming weeks, we’ll be breaking down common — yet potentially confusing — terms you will undoubtedly come across in your learning journey.

At a base level, someone new to containers might understand they “contain” an application, but how does it work? What are the benefits and use-cases? (more…)
