Spark (Structured) Streaming vs. Kafka StreamsGuido Schmutz
Independent of the source of data, the integration and analysis of event streams gets more important in the world of sensors, social media streams and Internet of Things. Events have to be accepted quickly and reliably, they have to be distributed and analyzed, often with many consumers or systems interested in all or part of the events. In this session we compare two popular Streaming Analytics solutions: Spark Streaming and Kafka Streams.
Spark is fast and general engine for large-scale data processing and has been designed to provide a more efficient alternative to Hadoop MapReduce. Spark Streaming brings Spark's language-integrated API to stream processing, letting you write streaming applications the same way you write batch jobs. It supports both Java and Scala.
Kafka Streams is the stream processing solution which is part of Kafka. It is provided as a Java library and by that can be easily integrated with any Java application.
This presentation shows how you can implement stream processing solutions with each of the two frameworks, discusses how they compare and highlights the differences and similarities.
Spark Streaming allows processing of live data streams in Spark. It integrates streaming data and batch processing within the same Spark application. Spark SQL provides a programming abstraction called DataFrames and can be used to query structured data in Spark. Structured Streaming in Spark 2.0 provides a high-level API for building streaming applications on top of Spark SQL's engine. It allows running the same queries on streaming data as on batch data and unifies streaming, interactive, and batch processing.

The Advantages of Using a Private Cloud Over a Virtual Private CloudWhizlabs
With the boom of virtual private Cloud, people have not forgotten the efficacy of a private cloud for serving specific purposes. The Private Cloud is a single cloud environment that is dedicated to run on individual infrastructure. It usually functions with off-site data centers or is carried out by managed private cloud service providers on the premises.
The reason why people still prefer private Cloud over the public and virtual Cloud is for its exclusivity and control. You do not have to share the hosted resources with anyone but keep it only to yourself. To know more please visit https://www.whizlabs.com/blog/the-advantages-of-using-a-private-cloud-over-a-virtual-private-cloud/
Virtual private cloud gives the users a private environment suitable for cloud computing that is contained within a public cloud. A virtual private cloud can be used for storing data, running codes, hosting websites, and everything else that you intend to do in any usual private cloud. As the public cloud computing environment is highly crowded, you will still get that private space within it to carry out your operations.

allows an application to run on Hadoop cluster, up to 100 times faster in
memory, and 10 times faster on disk.
▪ Runs Everywhere
Spark can run on multiple platforms without affecting the processing
speed. It can run on Hadoop, Kubernetes, Mesos, Standalone, and even
in the Cloud.
8. Apache Spark Features
▪ General Purpose
The spark is a powered by the plethora of libraries for machine learning i.e.
MLlib, DataFrames, and SQL along with Spark Streaming and GraphX. One is
allowed to use a combination of these libraries coherently in an application.
The feature of combining streaming, SQL, and complex analytics, and using in
the same application makes Spark a general-purpose framework.
▪ Advanced Analytics
Apache Spark is known to support ‘Map’ and ‘Reduce’ that has been
mentioned earlier. But along with MapReduce, it supports Streaming data,
SQL queries, Graph algorithms, and Machine learning. Thus, Apache Spark is a
great mean of performing advanced analytics.
9. Apache Spark Components
Apache Spark Ecosystem comprises of various Apache Spark components that are
responsible for the functioning of the Apache Spark. There are 5 components of Apache
Spark that constitute Apache Spark ecosystem.
▪ Spark Core
The main execution engine of the Spark platform is known as Spark Core. All the
working and functionality of Apache Spark depends on the Spark Core including
memory management, task scheduling, fault recovery, and others. It enables in-
memory processing and is responsible to define RDD (Resilient Distributed Dataset) by
an API that is the programming abstraction of Spark.
▪ Spark SQL and DataFrames
The Spark SQL is the main component of Spark that works with the structured data and
supports structured data processing. Spark SQL comes with a programming abstraction
known as DataFrames. Spark SQL enables developers to combine SQL queries with
manipulated programmatic data that are supported by RDDs in different languages.
11. Apache Spark Components
▪ Spark Streaming
This Spark component is responsible for the live stream data processing such as log
files created by production web servers. It provides API for the manipulation of data
streams, thus makes it easy to learn Apache Spark project. This component is also
responsible for throughput, scalability, and fault tolerance as that of the Spark Core.
▪ MLlib
MLlib is the in-built library of Spark that contains the functionality of Machine
Learning, known as MLlib. It provides various ML algorithms such as clustering,
classification, regression, collaborative filtering and supporting functionality. MLlib
also contains many low-level machine learning primitives.
▪ GraphX
GraphX is the library that enables graph computations. GraphX also provides an API
to perform graph computation by allowing users generate directed graph using
arbitrary properties of the edge and vertex.
12. Apache Spark Languages
Apache Spark is written in Scala. So, Scala is the native language
used to interact with the Spark Core. Besides, the APIs of Apache
Spark has been written in other languages, these are
▪ Scala
▪ Java
▪ Python
▪ R
As the framework of Spark is built on Scala, it can offer some great
features as compared to other Apache Spark languages. Using
Scala with Apache Spark provides you access to the latest features.
According to a Spark Survey on Apache Spark Languages, 71% of
Spark developers are using Scala, 58% are using Python, 31% are
using Java, while 18% are using R language.
14. Apache Spark History
Apache Spark introduction cannot actually begin without mentioning the
history of Apache Spark. So, let’s state in brief, Spark was first introduced
in the year 2009 in UC Berkeley R&D Lab, now AMP Lab by M. Zaharia.
And then Spark was open-sourced under BSD License in the year 2010.
In 2013, the Spark project was donated to Apache Software Foundation
and the BSD license turned into Apache 2.0. In 2014, Spark became a top-
level project of Apache Foundation, known as Apache Spark.
In 2015, with the effort of over 1000 contributors, Apache Spark became
one of the most active Apache projects as well as most active open source
project of big data. Till date,. Apache Spark version 2.3.0 has recently
been released on Feb 28th, 2018 which is the latest version of Apache
Spark.
16. Why You Should Learn Apache
SparkWith the generation of big data by businesses, it has become very
important to analyze that data to understand business insights. Spark is a
revolutionary framework on big data processing land. Enterprises are
extensively adopting Spark which in turn is increasing demand for Apache
Spark developers.
According to O'Reilly Data Science Salary Survey, the salary of developers
is a function of their Apache skills. Scala language and Apache Spark skills
give a good boost to your existing salary. Apache Spark developers are
known as the programmers who receive the highest salary in
development. With the increasing demand for Apache Spark developers
and their salary level, it is the right time for development professionals to
learn Apache Spark and thus help enterprises to perform analysis of data.
17. Why You Should Learn Apache

18. Do You Need Hadoop to Run
Spark?Spark and Hadoop are the most popular big data processing
frameworks. Being faster than MapReduce, Apache Spark has taken an
edge over the Hadoop in terms of speed. Also, Spark can be used for
the processing of different kind of data including real-time whereas
Hadoop can only be used for the batch processing.
Although Hadoop and Spark don’t do the same thing but can still work
together. Spark is responsible for the faster and real-data processing of
data in Hadoop. To achieve maximum benefits, one can run Spark in
the distributed mode using HDFS.
So, it is not the case that we always need Hadoop to run Spark. But if
you want to run Spark with Hadoop, HDFS is the main requirement to
run Spark in the distributed mode.
