Apache Hadoop Marries OpenStack Sahara
OpenStack Sahara for Hadoop: Why and How | Stratoscale http://ow.ly/XyQZd
This is a great article to use for reference from Statoscale.
It explains how Sahara is used to create Hadoop Clusters on OpenStack.
Sahara is a OpenStack project (formally known as Savanna) with its main purpose to simplify installing Hadoop,Spark and Storm clusters.Sahara can install and mange several clusters at the same time, add new and remove old nodes from the cluster.
Here is a great article about the difference between Hyper-Convergence and Convergence?
The Hyper-convergence of cloud computing infrastructure is now a reality. The growing success of OpenStack implementations in public and private clouds is testimony to the trend of Hyper-convergence.
Hyper-convergence simply means modular distributed systems running on commodity hardware that are by design massively scalable, fault tolerant and reliable.
Now a few questions come to the fore. How are Hyper-converged systems different from traditional converged systems? What is fostering Hyper-convergence trend in the age of multi-clouds (public,private and hybrid clouds)? What are the benefits of Hyper-converged systems? How is OpenStack enabling Hyper-convergence?
We will examine all these questions in this post.
Converged systems are a natural extension of traditional IT infrastructure, which previously existed and operated in silos. The converged systems combined two or more of these technologies to provide pre-engineered systems.
The pre-engineered converged systems are separate technology components engineered to work well when combined…
