Big data as a service – How does it work?
Oversigt: I dagens teknologiverden,,en,software som en service,,en,er en almindelig model,,en,Tjenesten, hvis den tilbydes abonnenterne efter behov,,en,Big data følger også servicemodellen,,en,Jeg vil tale om,,en, software as a service (SaaS) is a common model. The service if offered to the subscribers as per need basis. Big data is also following the service model. In this article, I will talk about the service model followed in big data technology domain.
Here is a description for some well-known service models for Big Data as a service
Rackspace:
Rackspace Hadoop clusters could run Hadoop on Rackspace managed dedicated servers, public cloud or private cloud.
OneMetal for cloud big data is provided by Rackspace for Apache Spark and Hadoop. It offers a fully managed bare-metal platform for in-memory processing.
