Hadoop Training in Pune
Hadoop is an Apache open source framework written in Java that allows distributed processing of large data sets across clusters of computers using simple programming models. A Hadoop frame-worked application works in an environment that provides distributed storage and computation across clusters of computers. Hadoop is designed to scale up from a single server to thousands of machines, each offering local computation and storage.
We have multiple branches in Pune with our training institutes at Deccan and Pimple Saudagar for the student convenience. Our training centers are advancly equipped with good infrastructure and ready to use for students. We keep updating our hadoop syllabus which give our student updated course knowledge.We try to provide Best Hadoop Training in Pune.
WHAT IS “BIGDATA”?
Bigdata is nothing but a large volume of data or a huge size of files. It can be in a structured form or may be unstructured. Mostly and widely Bigdata is known because it can be used to analyze the data for better business decisions and also to help them in making future business strategies. To understand Hadoop candidate should have the prerequisites as Java, SQL and little knowledge of LINUX, 3RI Technologies is offering the Big Data Hadoop Training in Pune with all above stated prerequisites. Ideally, there are 3 major aspects which make Bigdata so powerful-
- Volume:- Earlier Data collection was a tough task for any organization since data can be of a flat file, CSV file, pipe delimited, spreadsheets form, social media or maybe core business transactions. Hadoop makes life easy for these organizations who dealt with large data.
- Speed:- Typically it shows the rate by which you receive or transfer the data from one node to another. This we can understand by the simple example of Facebook where we comment, like and share any post and it gets reflected in the very next moment, which is nothing but the speed of Bigdata.
- Variety:- The very major advantage of Bigdata is that it can handle very many varieties of data as mentioned in Volume section, Bigdata can handle structured format, unstructured documents such as text, email, video, audio, or financial transaction data.
WHAT IS HADOOP?
Fundamentally Hadoop is an open source infrastructure framework that allows store and processes the huge size of data or Bigdata. Since it is based on a cluster system, it works in a Master-Slave Architecture. In Master-Slave Architecture, the large data can be stored and processed in parallel. Structured, semi-structured and unstructured of data can be analyzed, Components of Hadoop
- HDFS: Hadoop Distributed File System
- Map Reduce
- Hadoop Common
3RI Technologies provide all the topics in detail for Hadoop and Bigdata contents, from scratch as MapReduce, PIG, HIVE, FLUME, SQOOP etc in our Hadoop Training in Pune course.
ADVANTAGES FOR ENTERPRISES:
The most important and valuable takeaway from Hadoop Bigdata is a business can analyze their past data and make the business strategies for the future:
- Better Decision making
- Time to develop new products.
WHAT HADOOP DOES?
- It provides you cost effective storage solution for data.
- It provides easy to access a variety of data and analyze it quickly and effectively.
- It provides scalability in terms of storage.
- It is widely adopted now by different domains like healthcare, e-commerce, retail, BFSI, Supply Chain Management, Telecommunications, etc.
- Since it works on multiple unstructured nodes, there will be always a copy of data in case it failed on a particular node.
- Hadoop is a faster, cost-effective and fastest technology in terms of data storage and data analysis.
ADVANTAGES OVER RDBMS
RDBMS is more suitable for relational data as it works on tables. The main feature of the relational database includes an ability to use tables for data storage while maintaining and enforcing certain data relationships.
|Data Variety||Mainly for Structured data.||Used for Structured, Semi-Structured and Unstructured data|
|Data Storage||Average size data (GBs)||Use for large data set (Tbs and Pbs)|
|Querying||SQL Language||HQL (Hive Query Language)|
|Schema||Required on write (static schema)||Required on read (dynamic schema)|
|Speed||Reads are fast||Both reads and writes are fast|
|Use Case||OLTP (Online transaction processing)||Analytics (Audio, video, logs etc), Data Discovery|
|Data Objects||Works on Relational Tables||Works on Key/Value Pair|
|Hardware Profile||High-End Servers||Commodity/Utility Hardware|
Initially if you have a knowledge of RDBMS, it is good to learn HDFS. But, sometimes people are coming from configuration management, data analytics, freshers or from non-IT background, we teach them Oracle SQL(RDBMS) and then teach them HDFS in our Best Hadoop Training in Pune Course.
Because of its low-cost implementation Hadoop is attracting the business to adopt it more conveniently. As per a report by Allied Market Research, The market for Hadoop is projected to rise from a $1.5 billion in 2012 to an estimated $16.1 billion by 2020. Significantly observed that the DBMS industry has expanded from application and web into healthcare, retails, e-commerce, banking, hospitals, and government, etc. This expansion creates a huge demand for cost-effective platforms which can be scalable like Hadoop. The key to the success of Hadoop is nothing but the advantages it provides to end users:
- Resilience to failure
Importance of Big Data Analytics There is no doubt that Big Data analytics is a revolution in the field of Information Technology. Companies have realized its advantages and are enhancing their usages day by day. Since any business is based on users, this field is flourishing in Business to Consumer (B2C) applications. We can divide Big Data analytics into three divisions as:
- Prescriptive Analytics
- Predictive Analytics
- Descriptive Analytics.
Why Bigdata analytics is so important today? There are 4 mainly observed perspectives, due to which Bigdata is in huge demand nowadays.
- Data Science Perspective
- Business Perspective
- Real-time Usability Perspective
- Job Market Perspective
