Video of 14.1. NoSQL Scaling Out / Up in Apache Hadoop course by CloudxLab Official channel, video No. 71 free certified online
Welcome to the session on NoSQL
In this session, we will learn What, why and how about NoSQL.
What does it mean by scale out and scale up?
Say, we have a cart with a single horse and we need to carry more than a horse can handle.
We can replace the horse with an elephant and carry a higher load. This approach is called scaling up or vertical scaling. We may not be able to carry load higher than an elephant can carry.
If we add more horses to the cart, it is called horizontal scaling or scaling out.
Basically, if we have to handle higher computing load and we choose to upgrade the hardware, we call it vertical scaling or scaling up.
But if we choose to move to a distributed architecture and add more computers to solve our problem we call it horizontal scaling or scaling out.
NoSQL databases are needed when we want to horizontally scale.
This Big Data Tutorial will help you learn HDFS, ZooKeeper, Hive, HBase, NoSQL, Oozie, Flume, Sqoop, Spark, Spark RDD, Spark Streaming, Kafka, SparkR, SparkSQL, MLlib, and GraphX from scratch. Everything in this course is explained with the relevant example thus you will actually know how to implement the topics that you will learn in this course.
Let us know in the comments below if you find it helpful.
